Quality Assurance/Quality Control Procedures for the State Automatic Monitoring
System for Ambient Air Quality in the Republic of Macedonia
State Automatic Monitoring System for Ambient Air Quality (SAMSAAQ) is consisted by:
Air Quality Calibration LaboratoryState Air Quality Monitoring Network (17th monitoring stations and 10 LVS and HVS samplers)Air Quality data Management/collection System (Airviro)
STRUCTURE OF THE SAMSAAQ
The Quality System is established, implemented and maintained by Division for Air Quality Monitoring and includes the following documents:
Quality manual,
SOPs,
Registers,
Forms,
Report,
QA/QC procedures,
Plans,
Lists,
Data base,
Reporting,
Records etc;
All policies, systems, programs, procedures and instruction are documented to enable the SAMSAAQ to assure the quality of generated results.

THE STANDARD OPERATING PROCEDURES
The Standard Operating Procedures (SOPs) describe in details all processes and activities that take places in the Calibration laboratory, Monitoring network and Data management system. They are divided in different sections:
Section A: General (5 SOPs); Section C for Calibration methods in the Calibration
laboratory (7 SOPs); Section D for the Analysis methods (11 SOPs); Section E for Data analysis and report (3 SOPs); Section F for Field measurements (2 SOPs) and Section G for Data management (3 SOPs).

SOP-G3 Data Reporting
Uncertainty calculations have been performed for each of the calibration concentration prepared by different calibration methods and they are presented at each of the SOP-C1 to C4.
In addition the uncertainty of the analysis methods are prepared for the laboratory measurements and for field measurements.
Uncertainty budget
Internal audit was performed at the measuring site and in laboratory.
The Audit questionnaire was fulfilled and Audit report issued.
Internal audit identified nonconformities and the corrective actions should be follow and immediately realized in order to be able to fulfill the data quality objectives for the measurements.
Internal audit
The data quality objectives for the air quality measurements at the measurement stations can be easily became unsatisfactory due to the lack of:
spare parts; certified calibration gas standards; regular costs for maintenance and service of
the measuring instruments; employees; specialized trainings.
Data quality objectives
All prepared SOPs concerning all relevant activities of the system are in use;
The uncertainty budget for the air quality measurements was built up;
QA/QC procedures are in full operation;
The air quality web portal was developed where Air quality data are presented in real time: http://airquality.moepp.gov.mk/
Participation to the interlaboratory comparison exercises organized by EC/JRC and by WHO;
Participation to the meetings of AQUILA group.
