AIRBORNE PARTICULATE MATTER IN THE UNITED KINGDOM. THIRD REPORT OF THE QUALITY OF URBAN AIR REVIEW GROUP

This report reviews knowledge of the sources, chemical composition, physical properties, and concentrations of airborne particles, and examines the implications for control of particulate matter in UK urban air. It includes sections on: (1) the properties of airborne particulate material; (2) measurement methods; (3) sources and emissions of primary and secondary particulate matter; (4) concentrations and trends in particulate matter; (5) the chemical composition of airborne particles; and (6) effects of airborne particulate materials on health, visibility, cleanness, and climate change. Road transport is a significant source of primary particle emissions, especially in urban areas. It accounts for about a third of emissions of PM10 in the UK and over 80% of these emissions in London. Particle number concentration is greatly raised near a busy road, by a factor much greater than the rise in PM10 mass. The major sources of particulates on roads are vehicle exhaust emissions and aerosols from sea and deicing salts; their seasonal variations are indicated. 15 research recommendations are made, including further studies of particulate emissions from vehicles (from exhaust pipes and tyre and brake wear) and more roadside particle counts.
