Introduction to the validation project Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures in particular for sludge soils and biowastes It was created as in response to the European Commission Mandate M 330 given to CEN asking for the development and validation of those standards in support of forthcoming EU Directives such as

o The revision of the Sewage Sludge Directive 86278EEC o The Directive on the biological treatment of biodegradable waste o The initiative on a legal framework for soil monitoring in Europe

This mandate explicitly considers standards for the entire analytical procedure (ie sampling pre-treatment and analytical measurement methods for inorganic organic hygiene and biological parameters) These are grouped into classes according to their physicalchemical properties which in turn determine the methods needed to quantify the potential impact on human and animal health plant uptake soil function and groundwater quality As the materials generally feature a mixture of different types of contaminants it is important to provide an integrated answer covering evaluation of all relevant pollutants In order to fulfil the requirements of the aforementioned mandate the European Commissions Joint Research Centre (JRC) and its Directorate-General for Environment (DG ENV) together with the Technical Committees of the European Standardisation Committee (CEN TCs) concerned designed a pre-normative research initiative called Project HORIZONTAL and presented it to the Commission and the Environmental Authorities in the Member States After an extensive literature research and careful evaluation of the feasibility of a given horizontal standard the standards were drafted and finally validated in a European laboratory intercomparison The underlying statistical concept information about the materials used details about the participants measurement results obtained as well as the derived performance characteristics obtained for the determination of mercury in aqua regia and nitric acid digests by cold vapour atomic absorption spectrometry (CV-AAS) are described hereafter

11 Statistical concept underlying the validation According to the requirements of the work package concerning data handling amp interpretation of the project HORIZONTAL-ORG the respective validation intercomparisons have to be evaluated according to the principles laid down in ISO standard 5725-21994 In particular repeatability and reproducibility of the draft standard methods have to be determined The determination of trueness would require the availability of independent reference values for the materials investigated This however is not possible and was not requested in the frame of this work In the following the approach chosen is explained

111 Introduction to the statistical model The statistical model used in ISO 5725 for estimation of accuracy of a measurement method assumes that every test result is the sum of three components

eBmy ++= y test result m general mean B laboratory component of bias under repeatability conditions e random error occurring in every measurement under repeatability conditions

In the workprogram the quantification of term e is explicitly asked for (ie repeatability and reproducibility) The repeatability variance is measured directly as the variance of the error term e but the reproducibility depends on the sum of the repeatability variance and the between-laboratory variance

( )er var=σ 22rLR σσσ += with ( )BL var=σ

However soil biowaste and sludge are multi-phase materials ie they contain two or more distinct types of particles which are fundamentally different in their properties and composition As a consequence this introduces an important source of variation for the intercomparison exercise which needs to be considered ie the inherent heterogeneity of the materials Thus a contribution of variation between samples H is introduced to the general statistical model

HeBmy +++= Using ANOVA techniques the different variances are calculated and separated for the evaluation

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

enter their data in a structured form For authentication purposes a signed printout had to be submitted by mail The online data submission included a detailed questionnaire for additional information on the measurements

113 Statistical analysis Statistical analysis of data followed the requirements of ISO 5725-21994 and ISO 5725-51998 Appropriate tests for the homogeneity of variance detection of outliers and normal distribution were applied Statistical evaluation was done using an Excel Macro developed tested and successfully applied in other occasion by ECN Evaluation was executed jointly by JRC and ECN

12 Validation exercise for CV-AAS

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

Introduction to the validation project Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures in particular for sludge soils and biowastes It was created as in response to the European Commission Mandate M 330 given to CEN asking for the development and validation of those standards in support of forthcoming EU Directives such as

o The revision of the Sewage Sludge Directive 86278EEC o The Directive on the biological treatment of biodegradable waste o The initiative on a legal framework for soil monitoring in Europe

This mandate explicitly considers standards for the entire analytical procedure (ie sampling pre-treatment and analytical measurement methods for inorganic organic hygiene and biological parameters) These are grouped into classes according to their physicalchemical properties which in turn determine the methods needed to quantify the potential impact on human and animal health plant uptake soil function and groundwater quality As the materials generally feature a mixture of different types of contaminants it is important to provide an integrated answer covering evaluation of all relevant pollutants In order to fulfil the requirements of the aforementioned mandate the European Commissions Joint Research Centre (JRC) and its Directorate-General for Environment (DG ENV) together with the Technical Committees of the European Standardisation Committee (CEN TCs) concerned designed a pre-normative research initiative called Project HORIZONTAL and presented it to the Commission and the Environmental Authorities in the Member States After an extensive literature research and careful evaluation of the feasibility of a given horizontal standard the standards were drafted and finally validated in a European laboratory intercomparison The underlying statistical concept information about the materials used details about the participants measurement results obtained as well as the derived performance characteristics obtained for the determination of mercury in aqua regia and nitric acid digests by cold vapour atomic absorption spectrometry (CV-AAS) are described hereafter

11 Statistical concept underlying the validation According to the requirements of the work package concerning data handling amp interpretation of the project HORIZONTAL-ORG the respective validation intercomparisons have to be evaluated according to the principles laid down in ISO standard 5725-21994 In particular repeatability and reproducibility of the draft standard methods have to be determined The determination of trueness would require the availability of independent reference values for the materials investigated This however is not possible and was not requested in the frame of this work In the following the approach chosen is explained

111 Introduction to the statistical model The statistical model used in ISO 5725 for estimation of accuracy of a measurement method assumes that every test result is the sum of three components

eBmy ++= y test result m general mean B laboratory component of bias under repeatability conditions e random error occurring in every measurement under repeatability conditions

In the workprogram the quantification of term e is explicitly asked for (ie repeatability and reproducibility) The repeatability variance is measured directly as the variance of the error term e but the reproducibility depends on the sum of the repeatability variance and the between-laboratory variance

( )er var=σ 22rLR σσσ += with ( )BL var=σ

However soil biowaste and sludge are multi-phase materials ie they contain two or more distinct types of particles which are fundamentally different in their properties and composition As a consequence this introduces an important source of variation for the intercomparison exercise which needs to be considered ie the inherent heterogeneity of the materials Thus a contribution of variation between samples H is introduced to the general statistical model

HeBmy +++= Using ANOVA techniques the different variances are calculated and separated for the evaluation

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

enter their data in a structured form For authentication purposes a signed printout had to be submitted by mail The online data submission included a detailed questionnaire for additional information on the measurements

113 Statistical analysis Statistical analysis of data followed the requirements of ISO 5725-21994 and ISO 5725-51998 Appropriate tests for the homogeneity of variance detection of outliers and normal distribution were applied Statistical evaluation was done using an Excel Macro developed tested and successfully applied in other occasion by ECN Evaluation was executed jointly by JRC and ECN

12 Validation exercise for CV-AAS

121 Elements to be measured Mercury was selected for the validation exercise

122 Samples dispatched for the validation of CV-AAS After a preliminary rough screening the following materials were used for the validation round of CV-AAS bull Compost 2 A pollutant loaded compost material from Germany bull Sewage Sludge 1 A mixed sewage sludge from Essen Germany bull Sewage Sludge 2 A mixed municipal WWTP sludge from North Rhine

Westphalia Germany bull Soil 1 A sludge amended soil from Duumlsseldorf

124 Analytical program Of each of the three materials 2 bottles had to be analyzed and each bottle had to analyze independently three times As mentioned above analyses were to be done under repeatability conditions Results were to be reported referring to DRY MATTER content The choice how to apply dm correction was free for each participant

125 Timing and Submission of data Dispatch of samples was done on the 18th of October 2006 For users of the Online data submission system (MILC) User Registration was possible from 14th of November 2006 with opening of the MILC Data Submission on 1st of December 2006 The deadline for submission of results has been set for CV-AAS to the 31st of January 2007 After that no further submission was possible Alternatively the participants were allowed to submit data electronically as Excel sheet using simply Email All data were treated in a confidential way Any presentation hereafter will refer only to numerical data and it will not be possible to identify the originating laboratory Lab Codes displayed are NOT related to the order of laboratories hereafter In addition to the information provide a Helpdesk was implemented in order to give quick and individual response to the participants during and immediately after the validation study In case of doubt and suspected transcription errors further enquires were conducted by JRC

1 Introduction This report gives an overview on the available analytical information on the following raw materials to be used for the production of validation materials of the so-called Project HORIZONTAL

bull Four sludge materials from Duumlsseldorf Germany

bull An agricultural soil material from Reading United Kingdom

bull A compost material from Vienna Austria

bull A compost material from Korschenbroich Germany

bull A sludge-amended agricultural soil from Pavia Province Italy

bull A sludge-amended soil from Barcelona Spain

bull A sludge-amended soil from Essen Germany

bull A long-term sludge exposed soil from Hohenheim Germany

The following analytical information was gathered partly before and during the sampling of the raw materials to be used for the production of the HORIZONTAL validation materials The material were sampled by IES and shipped to IRMM in the course of the year 2005 The information gathered was then completed by various analytical screenings for PAHs and PCBs done by the Institute for Reference Materials and Measurements Geel Belgium for phthalates done by UBA Berlin Germany for PBDE done by IIQAB-CSIC Barcelona Spain for trace elements and some selected major and minor elements by the Institute for Environment and Sustainability Ispra Italy

The work compiled hereafter is based on the numerous additional efforts of the scientists working at various members of the consortium Project HORIZONTAL-Org and contributing organisations

This work is gratefully acknowledged

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

Introduction to the validation project Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures in particular for sludge soils and biowastes It was created as in response to the European Commission Mandate M 330 given to CEN asking for the development and validation of those standards in support of forthcoming EU Directives such as

o The revision of the Sewage Sludge Directive 86278EEC o The Directive on the biological treatment of biodegradable waste o The initiative on a legal framework for soil monitoring in Europe

This mandate explicitly considers standards for the entire analytical procedure (ie sampling pre-treatment and analytical measurement methods for inorganic organic hygiene and biological parameters) These are grouped into classes according to their physicalchemical properties which in turn determine the methods needed to quantify the potential impact on human and animal health plant uptake soil function and groundwater quality As the materials generally feature a mixture of different types of contaminants it is important to provide an integrated answer covering evaluation of all relevant pollutants In order to fulfil the requirements of the aforementioned mandate the European Commissions Joint Research Centre (JRC) and its Directorate-General for Environment (DG ENV) together with the Technical Committees of the European Standardisation Committee (CEN TCs) concerned designed a pre-normative research initiative called Project HORIZONTAL and presented it to the Commission and the Environmental Authorities in the Member States After an extensive literature research and careful evaluation of the feasibility of a given horizontal standard the standards were drafted and finally validated in a European laboratory intercomparison The underlying statistical concept information about the materials used details about the participants measurement results obtained as well as the derived performance characteristics obtained for the determination of mercury in aqua regia and nitric acid digests by cold vapour atomic absorption spectrometry (CV-AAS) are described hereafter

11 Statistical concept underlying the validation According to the requirements of the work package concerning data handling amp interpretation of the project HORIZONTAL-ORG the respective validation intercomparisons have to be evaluated according to the principles laid down in ISO standard 5725-21994 In particular repeatability and reproducibility of the draft standard methods have to be determined The determination of trueness would require the availability of independent reference values for the materials investigated This however is not possible and was not requested in the frame of this work In the following the approach chosen is explained

111 Introduction to the statistical model The statistical model used in ISO 5725 for estimation of accuracy of a measurement method assumes that every test result is the sum of three components

eBmy ++= y test result m general mean B laboratory component of bias under repeatability conditions e random error occurring in every measurement under repeatability conditions

In the workprogram the quantification of term e is explicitly asked for (ie repeatability and reproducibility) The repeatability variance is measured directly as the variance of the error term e but the reproducibility depends on the sum of the repeatability variance and the between-laboratory variance

( )er var=σ 22rLR σσσ += with ( )BL var=σ

However soil biowaste and sludge are multi-phase materials ie they contain two or more distinct types of particles which are fundamentally different in their properties and composition As a consequence this introduces an important source of variation for the intercomparison exercise which needs to be considered ie the inherent heterogeneity of the materials Thus a contribution of variation between samples H is introduced to the general statistical model

HeBmy +++= Using ANOVA techniques the different variances are calculated and separated for the evaluation

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

enter their data in a structured form For authentication purposes a signed printout had to be submitted by mail The online data submission included a detailed questionnaire for additional information on the measurements

113 Statistical analysis Statistical analysis of data followed the requirements of ISO 5725-21994 and ISO 5725-51998 Appropriate tests for the homogeneity of variance detection of outliers and normal distribution were applied Statistical evaluation was done using an Excel Macro developed tested and successfully applied in other occasion by ECN Evaluation was executed jointly by JRC and ECN

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

Introduction to the validation project Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures in particular for sludge soils and biowastes It was created as in response to the European Commission Mandate M 330 given to CEN asking for the development and validation of those standards in support of forthcoming EU Directives such as

o The revision of the Sewage Sludge Directive 86278EEC o The Directive on the biological treatment of biodegradable waste o The initiative on a legal framework for soil monitoring in Europe

This mandate explicitly considers standards for the entire analytical procedure (ie sampling pre-treatment and analytical measurement methods for inorganic organic hygiene and biological parameters) These are grouped into classes according to their physicalchemical properties which in turn determine the methods needed to quantify the potential impact on human and animal health plant uptake soil function and groundwater quality As the materials generally feature a mixture of different types of contaminants it is important to provide an integrated answer covering evaluation of all relevant pollutants In order to fulfil the requirements of the aforementioned mandate the European Commissions Joint Research Centre (JRC) and its Directorate-General for Environment (DG ENV) together with the Technical Committees of the European Standardisation Committee (CEN TCs) concerned designed a pre-normative research initiative called Project HORIZONTAL and presented it to the Commission and the Environmental Authorities in the Member States After an extensive literature research and careful evaluation of the feasibility of a given horizontal standard the standards were drafted and finally validated in a European laboratory intercomparison The underlying statistical concept information about the materials used details about the participants measurement results obtained as well as the derived performance characteristics obtained for the determination of mercury in aqua regia and nitric acid digests by cold vapour atomic absorption spectrometry (CV-AAS) are described hereafter

11 Statistical concept underlying the validation According to the requirements of the work package concerning data handling amp interpretation of the project HORIZONTAL-ORG the respective validation intercomparisons have to be evaluated according to the principles laid down in ISO standard 5725-21994 In particular repeatability and reproducibility of the draft standard methods have to be determined The determination of trueness would require the availability of independent reference values for the materials investigated This however is not possible and was not requested in the frame of this work In the following the approach chosen is explained

111 Introduction to the statistical model The statistical model used in ISO 5725 for estimation of accuracy of a measurement method assumes that every test result is the sum of three components

eBmy ++= y test result m general mean B laboratory component of bias under repeatability conditions e random error occurring in every measurement under repeatability conditions

In the workprogram the quantification of term e is explicitly asked for (ie repeatability and reproducibility) The repeatability variance is measured directly as the variance of the error term e but the reproducibility depends on the sum of the repeatability variance and the between-laboratory variance

( )er var=σ 22rLR σσσ += with ( )BL var=σ

However soil biowaste and sludge are multi-phase materials ie they contain two or more distinct types of particles which are fundamentally different in their properties and composition As a consequence this introduces an important source of variation for the intercomparison exercise which needs to be considered ie the inherent heterogeneity of the materials Thus a contribution of variation between samples H is introduced to the general statistical model

HeBmy +++= Using ANOVA techniques the different variances are calculated and separated for the evaluation

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

enter their data in a structured form For authentication purposes a signed printout had to be submitted by mail The online data submission included a detailed questionnaire for additional information on the measurements

113 Statistical analysis Statistical analysis of data followed the requirements of ISO 5725-21994 and ISO 5725-51998 Appropriate tests for the homogeneity of variance detection of outliers and normal distribution were applied Statistical evaluation was done using an Excel Macro developed tested and successfully applied in other occasion by ECN Evaluation was executed jointly by JRC and ECN

12 Validation exercise for CV-AAS

121 Elements to be measured Mercury was selected for the validation exercise

122 Samples dispatched for the validation of CV-AAS After a preliminary rough screening the following materials were used for the validation round of CV-AAS bull Compost 2 A pollutant loaded compost material from Germany bull Sewage Sludge 1 A mixed sewage sludge from Essen Germany bull Sewage Sludge 2 A mixed municipal WWTP sludge from North Rhine

2 Overview on property values

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

Introduction to the validation project Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures in particular for sludge soils and biowastes It was created as in response to the European Commission Mandate M 330 given to CEN asking for the development and validation of those standards in support of forthcoming EU Directives such as

o The revision of the Sewage Sludge Directive 86278EEC o The Directive on the biological treatment of biodegradable waste o The initiative on a legal framework for soil monitoring in Europe

This mandate explicitly considers standards for the entire analytical procedure (ie sampling pre-treatment and analytical measurement methods for inorganic organic hygiene and biological parameters) These are grouped into classes according to their physicalchemical properties which in turn determine the methods needed to quantify the potential impact on human and animal health plant uptake soil function and groundwater quality As the materials generally feature a mixture of different types of contaminants it is important to provide an integrated answer covering evaluation of all relevant pollutants In order to fulfil the requirements of the aforementioned mandate the European Commissions Joint Research Centre (JRC) and its Directorate-General for Environment (DG ENV) together with the Technical Committees of the European Standardisation Committee (CEN TCs) concerned designed a pre-normative research initiative called Project HORIZONTAL and presented it to the Commission and the Environmental Authorities in the Member States After an extensive literature research and careful evaluation of the feasibility of a given horizontal standard the standards were drafted and finally validated in a European laboratory intercomparison The underlying statistical concept information about the materials used details about the participants measurement results obtained as well as the derived performance characteristics obtained for the determination of mercury in aqua regia and nitric acid digests by cold vapour atomic absorption spectrometry (CV-AAS) are described hereafter

11 Statistical concept underlying the validation According to the requirements of the work package concerning data handling amp interpretation of the project HORIZONTAL-ORG the respective validation intercomparisons have to be evaluated according to the principles laid down in ISO standard 5725-21994 In particular repeatability and reproducibility of the draft standard methods have to be determined The determination of trueness would require the availability of independent reference values for the materials investigated This however is not possible and was not requested in the frame of this work In the following the approach chosen is explained

111 Introduction to the statistical model The statistical model used in ISO 5725 for estimation of accuracy of a measurement method assumes that every test result is the sum of three components

eBmy ++= y test result m general mean B laboratory component of bias under repeatability conditions e random error occurring in every measurement under repeatability conditions

In the workprogram the quantification of term e is explicitly asked for (ie repeatability and reproducibility) The repeatability variance is measured directly as the variance of the error term e but the reproducibility depends on the sum of the repeatability variance and the between-laboratory variance

( )er var=σ 22rLR σσσ += with ( )BL var=σ

However soil biowaste and sludge are multi-phase materials ie they contain two or more distinct types of particles which are fundamentally different in their properties and composition As a consequence this introduces an important source of variation for the intercomparison exercise which needs to be considered ie the inherent heterogeneity of the materials Thus a contribution of variation between samples H is introduced to the general statistical model

HeBmy +++= Using ANOVA techniques the different variances are calculated and separated for the evaluation

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

enter their data in a structured form For authentication purposes a signed printout had to be submitted by mail The online data submission included a detailed questionnaire for additional information on the measurements

113 Statistical analysis Statistical analysis of data followed the requirements of ISO 5725-21994 and ISO 5725-51998 Appropriate tests for the homogeneity of variance detection of outliers and normal distribution were applied Statistical evaluation was done using an Excel Macro developed tested and successfully applied in other occasion by ECN Evaluation was executed jointly by JRC and ECN

12 Validation exercise for CV-AAS

121 Elements to be measured Mercury was selected for the validation exercise

122 Samples dispatched for the validation of CV-AAS After a preliminary rough screening the following materials were used for the validation round of CV-AAS bull Compost 2 A pollutant loaded compost material from Germany bull Sewage Sludge 1 A mixed sewage sludge from Essen Germany bull Sewage Sludge 2 A mixed municipal WWTP sludge from North Rhine

Westphalia Germany bull Soil 1 A sludge amended soil from Duumlsseldorf

bull Soil 2 A sludge amended soil from Pavia A more detailed description of background concentrations can be found in Annex 2 to this report The samples were dispatched simultaneously to all participants using a private courier service

123 Draft standards to be followed The draft standards to be followed could be downloaded following this link which is situated on the website of the Project HORIZONTAL httpwwwecnnldocssocietyhorizontalAnalysis_mercury_for_validationpdf

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

Introduction to the validation project Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures in particular for sludge soils and biowastes It was created as in response to the European Commission Mandate M 330 given to CEN asking for the development and validation of those standards in support of forthcoming EU Directives such as

o The revision of the Sewage Sludge Directive 86278EEC o The Directive on the biological treatment of biodegradable waste o The initiative on a legal framework for soil monitoring in Europe

This mandate explicitly considers standards for the entire analytical procedure (ie sampling pre-treatment and analytical measurement methods for inorganic organic hygiene and biological parameters) These are grouped into classes according to their physicalchemical properties which in turn determine the methods needed to quantify the potential impact on human and animal health plant uptake soil function and groundwater quality As the materials generally feature a mixture of different types of contaminants it is important to provide an integrated answer covering evaluation of all relevant pollutants In order to fulfil the requirements of the aforementioned mandate the European Commissions Joint Research Centre (JRC) and its Directorate-General for Environment (DG ENV) together with the Technical Committees of the European Standardisation Committee (CEN TCs) concerned designed a pre-normative research initiative called Project HORIZONTAL and presented it to the Commission and the Environmental Authorities in the Member States After an extensive literature research and careful evaluation of the feasibility of a given horizontal standard the standards were drafted and finally validated in a European laboratory intercomparison The underlying statistical concept information about the materials used details about the participants measurement results obtained as well as the derived performance characteristics obtained for the determination of mercury in aqua regia and nitric acid digests by cold vapour atomic absorption spectrometry (CV-AAS) are described hereafter

11 Statistical concept underlying the validation According to the requirements of the work package concerning data handling amp interpretation of the project HORIZONTAL-ORG the respective validation intercomparisons have to be evaluated according to the principles laid down in ISO standard 5725-21994 In particular repeatability and reproducibility of the draft standard methods have to be determined The determination of trueness would require the availability of independent reference values for the materials investigated This however is not possible and was not requested in the frame of this work In the following the approach chosen is explained

111 Introduction to the statistical model The statistical model used in ISO 5725 for estimation of accuracy of a measurement method assumes that every test result is the sum of three components

eBmy ++= y test result m general mean B laboratory component of bias under repeatability conditions e random error occurring in every measurement under repeatability conditions

In the workprogram the quantification of term e is explicitly asked for (ie repeatability and reproducibility) The repeatability variance is measured directly as the variance of the error term e but the reproducibility depends on the sum of the repeatability variance and the between-laboratory variance

( )er var=σ 22rLR σσσ += with ( )BL var=σ

However soil biowaste and sludge are multi-phase materials ie they contain two or more distinct types of particles which are fundamentally different in their properties and composition As a consequence this introduces an important source of variation for the intercomparison exercise which needs to be considered ie the inherent heterogeneity of the materials Thus a contribution of variation between samples H is introduced to the general statistical model

HeBmy +++= Using ANOVA techniques the different variances are calculated and separated for the evaluation

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

enter their data in a structured form For authentication purposes a signed printout had to be submitted by mail The online data submission included a detailed questionnaire for additional information on the measurements

113 Statistical analysis Statistical analysis of data followed the requirements of ISO 5725-21994 and ISO 5725-51998 Appropriate tests for the homogeneity of variance detection of outliers and normal distribution were applied Statistical evaluation was done using an Excel Macro developed tested and successfully applied in other occasion by ECN Evaluation was executed jointly by JRC and ECN

12 Validation exercise for CV-AAS

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

Introduction to the validation project Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures in particular for sludge soils and biowastes It was created as in response to the European Commission Mandate M 330 given to CEN asking for the development and validation of those standards in support of forthcoming EU Directives such as

o The revision of the Sewage Sludge Directive 86278EEC o The Directive on the biological treatment of biodegradable waste o The initiative on a legal framework for soil monitoring in Europe

This mandate explicitly considers standards for the entire analytical procedure (ie sampling pre-treatment and analytical measurement methods for inorganic organic hygiene and biological parameters) These are grouped into classes according to their physicalchemical properties which in turn determine the methods needed to quantify the potential impact on human and animal health plant uptake soil function and groundwater quality As the materials generally feature a mixture of different types of contaminants it is important to provide an integrated answer covering evaluation of all relevant pollutants In order to fulfil the requirements of the aforementioned mandate the European Commissions Joint Research Centre (JRC) and its Directorate-General for Environment (DG ENV) together with the Technical Committees of the European Standardisation Committee (CEN TCs) concerned designed a pre-normative research initiative called Project HORIZONTAL and presented it to the Commission and the Environmental Authorities in the Member States After an extensive literature research and careful evaluation of the feasibility of a given horizontal standard the standards were drafted and finally validated in a European laboratory intercomparison The underlying statistical concept information about the materials used details about the participants measurement results obtained as well as the derived performance characteristics obtained for the determination of mercury in aqua regia and nitric acid digests by cold vapour atomic absorption spectrometry (CV-AAS) are described hereafter

11 Statistical concept underlying the validation According to the requirements of the work package concerning data handling amp interpretation of the project HORIZONTAL-ORG the respective validation intercomparisons have to be evaluated according to the principles laid down in ISO standard 5725-21994 In particular repeatability and reproducibility of the draft standard methods have to be determined The determination of trueness would require the availability of independent reference values for the materials investigated This however is not possible and was not requested in the frame of this work In the following the approach chosen is explained

111 Introduction to the statistical model The statistical model used in ISO 5725 for estimation of accuracy of a measurement method assumes that every test result is the sum of three components

eBmy ++= y test result m general mean B laboratory component of bias under repeatability conditions e random error occurring in every measurement under repeatability conditions

In the workprogram the quantification of term e is explicitly asked for (ie repeatability and reproducibility) The repeatability variance is measured directly as the variance of the error term e but the reproducibility depends on the sum of the repeatability variance and the between-laboratory variance

( )er var=σ 22rLR σσσ += with ( )BL var=σ

However soil biowaste and sludge are multi-phase materials ie they contain two or more distinct types of particles which are fundamentally different in their properties and composition As a consequence this introduces an important source of variation for the intercomparison exercise which needs to be considered ie the inherent heterogeneity of the materials Thus a contribution of variation between samples H is introduced to the general statistical model

HeBmy +++= Using ANOVA techniques the different variances are calculated and separated for the evaluation

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

enter their data in a structured form For authentication purposes a signed printout had to be submitted by mail The online data submission included a detailed questionnaire for additional information on the measurements

113 Statistical analysis Statistical analysis of data followed the requirements of ISO 5725-21994 and ISO 5725-51998 Appropriate tests for the homogeneity of variance detection of outliers and normal distribution were applied Statistical evaluation was done using an Excel Macro developed tested and successfully applied in other occasion by ECN Evaluation was executed jointly by JRC and ECN

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

European Commission EUR 23009 ENndash Joint Research Centre ndash Institute for Environment and Sustainability Title Project HORIZONTAL Validation Report on CV AAS Author(s) E Sobiecka H van der Sloot H Hovind B M Gawlik Luxembourg Office for Official Publications of the European Communities 2007 ndash 50 pp ndash 210 x 297 cm EUR ndash Scientific and Technical Research series ndash ISSN 1018-5593 ISBN 978-92-79-07409-7 Abstract Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures in particular for sludge soils and biowastes In the context of this standardization project a series of draft technical specification were designed upon an extensive desk study fine-tuned after expert consultations and finally validated in international intercomparisons exercise This report summarises the work performed within the validation study of the draft standard for the determination of mercury in aqua regia and nitric acid digests in soils sludge and treated bio-waste using by cold vapour atomic absorption spectrometry (CV AAS) It further explains the underlying statistical concept for the calculation of reproducibility and repeatability from intercomparisons data In addition all single values results of the statistical evaluation as well as background information on the validation materials used are described and explained

The mission of the JRC is to provide customer-driven scientific and technical support for the conception development implementation and monitoring of EU policies As a service of the European Commission the JRC functions as a reference centre of science and technology for the Union Close to the policy-making process it serves the common interest of the Member States while being independent of special interests whether private or national

11 Statistical concept underlying the validation According to the requirements of the work package concerning data handling amp interpretation of the project HORIZONTAL-ORG the respective validation intercomparisons have to be evaluated according to the principles laid down in ISO standard 5725-21994 In particular repeatability and reproducibility of the draft standard methods have to be determined The determination of trueness would require the availability of independent reference values for the materials investigated This however is not possible and was not requested in the frame of this work In the following the approach chosen is explained

111 Introduction to the statistical model The statistical model used in ISO 5725 for estimation of accuracy of a measurement method assumes that every test result is the sum of three components

eBmy ++= y test result m general mean B laboratory component of bias under repeatability conditions e random error occurring in every measurement under repeatability conditions

In the workprogram the quantification of term e is explicitly asked for (ie repeatability and reproducibility) The repeatability variance is measured directly as the variance of the error term e but the reproducibility depends on the sum of the repeatability variance and the between-laboratory variance

( )er var=σ 22rLR σσσ += with ( )BL var=σ

However soil biowaste and sludge are multi-phase materials ie they contain two or more distinct types of particles which are fundamentally different in their properties and composition As a consequence this introduces an important source of variation for the intercomparison exercise which needs to be considered ie the inherent heterogeneity of the materials Thus a contribution of variation between samples H is introduced to the general statistical model

HeBmy +++= Using ANOVA techniques the different variances are calculated and separated for the evaluation

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

enter their data in a structured form For authentication purposes a signed printout had to be submitted by mail The online data submission included a detailed questionnaire for additional information on the measurements

113 Statistical analysis Statistical analysis of data followed the requirements of ISO 5725-21994 and ISO 5725-51998 Appropriate tests for the homogeneity of variance detection of outliers and normal distribution were applied Statistical evaluation was done using an Excel Macro developed tested and successfully applied in other occasion by ECN Evaluation was executed jointly by JRC and ECN

12 Validation exercise for CV-AAS

121 Elements to be measured Mercury was selected for the validation exercise

122 Samples dispatched for the validation of CV-AAS After a preliminary rough screening the following materials were used for the validation round of CV-AAS bull Compost 2 A pollutant loaded compost material from Germany bull Sewage Sludge 1 A mixed sewage sludge from Essen Germany bull Sewage Sludge 2 A mixed municipal WWTP sludge from North Rhine

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

112 Requirements for precision experiment

Layout of the experiment A suite of 10 to 12 different materials (soil sludge and biowaste) has been made available for the intercomparison exercise For each parameter investigated at least 10 to laboratories should be nominated to participate The same laboratories should be used for different parameters as far as possible Due to the complexity of analysis and the respective workload to the laboratories it was decided to propose three materials for the validation of the CV-AAS draft standard Each laboratory received two bottles of each material and was be requested to perform 6 independent analyses per material1 (3 per bottle) using the respective draft standard methods The 6 analyses per material should be carried out under repeatability conditions (ie same operator2 same equipment within a short period of time) As far as possible also the different materials should be measured under repeatability conditions however changes of eg operator or equipment are permitted but must be reported Likewise different materials can be analysed on different days if necessary Equipment used in the experiment needed to be checked prior to the experiment according to the requirements of the draft standard The results of these checks have to be documented Similarly date and time of each measurement had to be recorded for verification of repeatability conditions An appropriate timeframe for the entire exercise has been set and was to be respected

Recruitment of the laboratories Each sub-workpackage leader of HORIZONTAL was asked to select the laboratories using the information from section 52 of ISO 5725-21994 and provide the signed questionnaires (see also Annex 1) The workpackage leaders were responsible for providing the laboratories with the draft standard method and explaining the context of this exercise

Preparation and use of the materials Materials used for the exercise were prepared according to the general requirements for reference materials as laid down in ISO Guide 34 Materials were accompanied by instructions for use

Reporting of results Online submissions of results using an internet-based IT platform as well as XLS-Spreadsheets were used In case of online data submission the participating laboratories received a unique and confidential login and password in due time enabling them to

1 Independent analysis means analysis of independent test portions applying the entire analytical scheme to this test portion from eg extraction to quantification For instance it does not mean replicate injections of aliquots into a GC-MS instrument 2 Operator in this context may also consist of a fixed team of persons eg one person performing extraction one clean-up one quantification

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

1 Introduction This report gives an overview on the available analytical information on the following raw materials to be used for the production of validation materials of the so-called Project HORIZONTAL

bull Four sludge materials from Duumlsseldorf Germany

bull An agricultural soil material from Reading United Kingdom

bull A compost material from Vienna Austria

bull A compost material from Korschenbroich Germany

bull A sludge-amended agricultural soil from Pavia Province Italy

bull A sludge-amended soil from Barcelona Spain

bull A sludge-amended soil from Essen Germany

bull A long-term sludge exposed soil from Hohenheim Germany

The following analytical information was gathered partly before and during the sampling of the raw materials to be used for the production of the HORIZONTAL validation materials The material were sampled by IES and shipped to IRMM in the course of the year 2005 The information gathered was then completed by various analytical screenings for PAHs and PCBs done by the Institute for Reference Materials and Measurements Geel Belgium for phthalates done by UBA Berlin Germany for PBDE done by IIQAB-CSIC Barcelona Spain for trace elements and some selected major and minor elements by the Institute for Environment and Sustainability Ispra Italy

The work compiled hereafter is based on the numerous additional efforts of the scientists working at various members of the consortium Project HORIZONTAL-Org and contributing organisations

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

1 Introduction This report gives an overview on the available analytical information on the following raw materials to be used for the production of validation materials of the so-called Project HORIZONTAL

bull Four sludge materials from Duumlsseldorf Germany

bull An agricultural soil material from Reading United Kingdom

bull A compost material from Vienna Austria

bull A compost material from Korschenbroich Germany

bull A sludge-amended agricultural soil from Pavia Province Italy

bull A sludge-amended soil from Barcelona Spain

bull A sludge-amended soil from Essen Germany

bull A long-term sludge exposed soil from Hohenheim Germany

The following analytical information was gathered partly before and during the sampling of the raw materials to be used for the production of the HORIZONTAL validation materials The material were sampled by IES and shipped to IRMM in the course of the year 2005 The information gathered was then completed by various analytical screenings for PAHs and PCBs done by the Institute for Reference Materials and Measurements Geel Belgium for phthalates done by UBA Berlin Germany for PBDE done by IIQAB-CSIC Barcelona Spain for trace elements and some selected major and minor elements by the Institute for Environment and Sustainability Ispra Italy

The work compiled hereafter is based on the numerous additional efforts of the scientists working at various members of the consortium Project HORIZONTAL-Org and contributing organisations

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

Subsequent screening led to the information displayed hereafter It should be stressed that the data were obtained as SCREENING information on the UNTREATED or partially treated raw materials Therefore the final target values which are relevant for the validation intercomparison can be different

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

1 Introduction This report gives an overview on the available analytical information on the following raw materials to be used for the production of validation materials of the so-called Project HORIZONTAL

bull Four sludge materials from Duumlsseldorf Germany

bull An agricultural soil material from Reading United Kingdom

bull A compost material from Vienna Austria

bull A compost material from Korschenbroich Germany

bull A sludge-amended agricultural soil from Pavia Province Italy

bull A sludge-amended soil from Barcelona Spain

bull A sludge-amended soil from Essen Germany

bull A long-term sludge exposed soil from Hohenheim Germany

The following analytical information was gathered partly before and during the sampling of the raw materials to be used for the production of the HORIZONTAL validation materials The material were sampled by IES and shipped to IRMM in the course of the year 2005 The information gathered was then completed by various analytical screenings for PAHs and PCBs done by the Institute for Reference Materials and Measurements Geel Belgium for phthalates done by UBA Berlin Germany for PBDE done by IIQAB-CSIC Barcelona Spain for trace elements and some selected major and minor elements by the Institute for Environment and Sustainability Ispra Italy

The work compiled hereafter is based on the numerous additional efforts of the scientists working at various members of the consortium Project HORIZONTAL-Org and contributing organisations

This work is gratefully acknowledged

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

Subsequent screening led to the information displayed hereafter It should be stressed that the data were obtained as SCREENING information on the UNTREATED or partially treated raw materials Therefore the final target values which are relevant for the validation intercomparison can be different

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

1 Introduction This report gives an overview on the available analytical information on the following raw materials to be used for the production of validation materials of the so-called Project HORIZONTAL

bull Four sludge materials from Duumlsseldorf Germany

bull An agricultural soil material from Reading United Kingdom

bull A compost material from Vienna Austria

bull A compost material from Korschenbroich Germany

bull A sludge-amended agricultural soil from Pavia Province Italy

bull A sludge-amended soil from Barcelona Spain

bull A sludge-amended soil from Essen Germany

bull A long-term sludge exposed soil from Hohenheim Germany

The following analytical information was gathered partly before and during the sampling of the raw materials to be used for the production of the HORIZONTAL validation materials The material were sampled by IES and shipped to IRMM in the course of the year 2005 The information gathered was then completed by various analytical screenings for PAHs and PCBs done by the Institute for Reference Materials and Measurements Geel Belgium for phthalates done by UBA Berlin Germany for PBDE done by IIQAB-CSIC Barcelona Spain for trace elements and some selected major and minor elements by the Institute for Environment and Sustainability Ispra Italy

The work compiled hereafter is based on the numerous additional efforts of the scientists working at various members of the consortium Project HORIZONTAL-Org and contributing organisations

21 Sludge materials from Duumlsseldorf Germany

The various sewage sludge materials originate from various installations in the North Rhine Westphalia and were produced and sampled by staff from the Landesumweltamt (LUA) NRW under the responsibility from Dr K Furtmann

In total four sludge materials (Sludge A and D from a major municipal WWTP Sludge B from a municipal WWTP with industrial input and Sludge C from a municipal WWTP with high PCB-Content) were obtained and will be blended to two final materials Before sampling the following analytical data for a typical sample were received

Subsequent screening led to the information displayed hereafter It should be stressed that the data were obtained as SCREENING information on the UNTREATED or partially treated raw materials Therefore the final target values which are relevant for the validation intercomparison can be different

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below

22 Agricultural soil material from Reading United Kingdom

The material was proposed by the University of Reading (S Nortcliff) and was sampled from a site called ldquoFrogmore Farmrdquo which was featured in the ldquoMetalsrdquo Report for HORIZONTAL This site is close to Reading with soils developed on flintyloamy periglacial materials over Chalk has a long and well documented history of sludge application The focus of the work of Nortcliff et al undertook at this site and the monitoring and control at the site (by Thames Water and the subsequent subsidiary bodies dealing with sludge application to soil) was on metals (and metal loads) with no analysis or indeed any form of investigation in to organics in the broadest sense

The analytical information produced in the context of the screening of the raw material is displayed below
