This paper has been prepared in accordance with the Directive 96/62/EC on Ambient

Air Quality Assessment and Management and DGXI guidance as outlined in

document AAQ/95/1/2. It addresses meeting NO2 air quality objectives for the

protection of human health, ecosystems and the environment, risk assessment, present

and future air quality and the costs and benefit of setting objectives. It does not

address indoor air pollution, deposition or synergistic effects between NO2 and other

pollutants, or climatic effects of nitrogen-containing pollutants. As per the Annex I of

the Directive it focuses on NO2.

 

In determining limit values and, as appropriate, alert thresholds for NO2 the following

elements must be kept in mind:

· Abatement strategies for reducing effects of NOx may in some areas, lead to

increasing photochemical ozone concentrations.

· Parts of the population may be exposed to significant indoor and/or workplace NO2

pollution, but this is outside the scope of the Directive.
