Expert Group report on nitrogen dioxide

This is a report of the Air Quality Expert Group (AQEG).

This report provides a detailed analysis of nitrogen dioxide in the UK. It addresses:

• Emissions sources and their past and projected trends.
• Meteorological and chemical processes that affect ambient nitrogen dioxide concentrations.
• Measurement methods and networks.
• Modelling and mapping methods and their coupling with measurements at monitoring sites to predict future concentrations of nitrogen dioxide.
• Analysis of monitoring data and projections of future concentrations and likely exceedences of air quality objectives and limit values.

This report does not address health effects, indoor air pollution or effects on ecosystems or vegetation. The later was dealt with in the National Expert Group on Transboundary Air Pollution (NEGTAP) Report on Transboundary Air Pollution: Acidification, Eutrophication and Ground-Level Ozone in the UK, published in 2001.
