Dispersion characteristic and Increment of traffic related particulate matter pollution in London

V Singh, R S Sokhi & J Kukkonen
Annual Aerosol Science Conference 2013

This paper discusses the dispersion characteristics and increment of traffic related PM10, PM2.5 and EC concentrations in the vicinity of the roads in London to determine the extent of exposure of people living near major roads. Citywide particulate matter (PM) concentrations have been modelled at high resolution with OSCAR system for year 2008. It has been estimated that the traffic contribution, for the people living in the vicinity (within 25m) of the busy roads, could be up to around 50 percent of the total PM10, PM2.5; and over 80 percent of the total EC concentration. It has been also found that the concentration of EC decreases much faster as compared to PM10 and PM2.5 with the distance from the road.

The Aerosol Society recognises the importance of our diverse community and believe that to produce the best quality science we must encourage a proactive and inclusive approach to equality. This can be achieved by developing and retaining a diverse range of talented people to achieve their full potential free from discrimination. We acknowledge our role in engaging with the wider aerosol science community to develop a fair and friendly environment by promoting equality, diversity and inclusion for all, recognising that we come from varying backgrounds and experiences.
