Air Pollution

Definition

“The introduction of chemicals , particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms or cause damage to the natural environment or built environment, into the atmosphere”.

“… a gas (or a liquid or solid dispersed through ordinary air) released in a big enough quantity to harm the health of people or other animals, kill plants or stop them growing properly, damage or disrupt some other aspect of the environment (such as making building crumble or cause other kind of nuisance (reduced visibility … or an unpleasant odor)”.

3

Classification of Pollutants

– Primary Pollutants, are directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide from a motor vehicle, or sulfur dioxide released from factories;

– Secondary Pollutants, are not emitted directly, They form in the air when primary pollutants react or interact e.g. ground level ozone.

– Some pollutants may be both.

4

Forms of Pollutants (Dust and gas)– Gases produced from combustion processes (carbon monoxide-CO;

carbon dioxide-CO2 ; and oxides of nitrogen).• Sources: power stations, heating plants, industrial processes, and

transportation;

– Sulphur dioxide (SO2) – released into the atmosphere as a result of burning fossil fuels containing sulphur.

• Sources: coal fired power stations and other industrial sources;

– Particulates of lead and other heavy metals arise from various activities, including combustion processes in motor vehicles, metal processing industries, and waste incineration;

– Volatile organic compounds (VOCs)• Sources: vehicle exhaust gases (either as unburned fuels or as

combustion products), evaporation of solvents and motor fuels;

5

– Chlorofluorocarbons (CFCs).• Sources: used in aerosol sprays, solvents, and as refrigerants in

fridges, freezers and air-conditioning units;

– Methane.• Sources: emitted during the production and transportation of coal,

natural gas oil, decomposition of organic wastes in landfills, and from herds and cattle;

– PM10 – small airborne particulate matter, the particles of which are .mץ10>

• Sources: emission from diesel engines;

– Various complex pollutants produced by the incomplete combustion of fuels – carcinogenic or highly toxic pollutants at small levels; dioxins, furans, polyaromatic hydrocarbons (PAHs), polycholrinated biphenyls (PCBs)

6

Classification of Sources of Air pollution

– Anthropogenic sources (human activity)• Stationery sources, e.g. power plants, manufacturing facilities, waste

incinerators;

• Mobile sources, motor vehicles, marine vessels, aircraft;

• Chemicals, dust and controlled burn practices in agriculture and forestry management;

• Fumes, from paint, hair spray, varnish, aerosol and other solvent;

• Waste deposition in landfills;

• Military, e.g. nuclear weapons, toxic gases, germ warfare;

7

– Natural sources

• Dust from natural sources (desert area);

• Smoke and carbon monoxide from wildfire;

• Volcanic activity;

• Methane (emitted by the digestion of food by animals);

• Vegetation (in some regions, emits environmentally significant amount of VOCs on warmer days);

• Radon gas from radioactive decay within the Earth’s crust.

8

• Effects of Air and Atmospheric Pollutants

– Climate change, largely linked to emission of six greenhouse gases, namely, nitrous oxides, carbon dioxide, PFCs, methane, CFCs and ground-level ozone (extreme weather events and changes in seasons);

– Acid rain, arises when sulphur dioxide and nitrogen oxides mix with water vapour to form very weak sulphuric acid and nitric acid solutions in rainfall (linked to killing of fish, birds and trees and cause damage to buildings).

– Health effects, principally affects the respiratory and cardiovascular system;

Consequences of Impact on Health Difficulty in breathing, wheezing, coughing, aggravation of existing

respiratory and cardiac conditions, pulmonary exacerbations, vascular dysfunction, increased thrombus formation, brain damage, cancer, and increased cardiovascular morbidity and mortality.

9

• WHO estimates that 2.4 million people die annually from causes directly attributable to air pollution;

• Epidemiological studies suggest that more than 500,000 Americans (310,000 Europeans) die annually from cardiopulmonary diseases linked to breathing fine particle air pollution;

• Empirical evidence has shown a strong correlation between pneumonia related deaths and air pollution from motor vehicles;

• Worldwide, more threats are linked to air pollution than automobile accidents;

10

• Objectives of Air Quality Management

– Air quality management policies and strategies should be set to maximize net benefits to society, consistent with maintaining a reasonable degree of fairness;

– Ongoing systematic efforts to reduce exposures should be taken until further reductions are not justifiable and efficient for cost-benefit reasons and societal support. Hot spots and geographical differences in air quality need to be identified and taken into account in exposure reduction strategies.

• Decision – Making Principles

– In location where air quality is poor and studies to characterize sources and impacts are in their infancy, uncertainties in the science should not delay the implementation of strategies to improve air quality;

– All policy (emission fees, emissions trading, voluntary programs, mandatory standard, etc) should be considered, including technological approaches and non-technological community-based behavioral solutions. There is also a need for a database of policy intervention case studies, including successes and failures.

11

• Tools and Capacities for Decision – Making

– Communication and consultation through an open and transparent multi-stakeholder process are important for establishing trust and support for air quality management decisions;

– Emissions inventories and monitoring networks need to be maintained and expanded as a basis for evaluating air quality on an ongoing basis. Emissions and monitoring data should be made publicly available;

– While improvements in institutional capacity in developing countries are undeniable, further improvements are needed to enhance the institutional capacity to carry out and enforce air quality policy.

12

• The Regulatory Challenge

– Air, unlike other environmental media, is intangible and not capable of being owned;

– It is a transient medium (uncontained and highly mobile);

– Often difficult to identify causal links between particular sources and effect of pollutants;

– Range of polluters and the sources of pollutant are varied and diverse;

– Raises the problem of uncertainly , risk and the application of a precautionary approach.

13

• Implication on Regulatory and Reduction Efforts

– The legal, scientific and economic complexity means that no single regulatory mechanism will suffice;

– Various types of mechanism must be used to deal with different facets of the same problem;

– All the significant sources such as energy production and consumption, transportation, manufacturing and agriculture are all interconnected (linked with industrialization & economic development)

14

• General Legal Controls

– Air quality standards• National Ambient Air Quality Standard• Air Quality Index

– Land use planning (zoning and transport infrastructure planning);

– Building regulations;
