ABSTRACT
Air pollution damages health, buildings and the environment. Pollution can be characterised by a long-range component, an intermediate-range component and a ‘local’ component.
In the urban environment, traffic pollution can account for up to 85 per cent of total emissions compared to a national average of 25 per cent.1
Pollutants resulting from traffic include CO, oxides of nitrogen (NOX), CO2, hydrocarbons and particles.
