Relating Vehicle Generated Pollutants to Urban Stormwater QualityJanaka M A Gunawardena Masters by Research 2008 - 2010 
Faculty Faculty of Built Environment and Engineering Supervisor/s Prof Sobana Goonetilleke, Aspro Godwin Ayoko Thesis Abstract Although the pollutants on road surfaces are mostly from traffic sources, other significant sources include industrial and household emissions. Hence, to relate vehicle-generated pollutants to build-up, contributions from other sources have to be identified.
Vehicle-generated particles which have a relatively higher specific gravity will be deposited either on road or nearby areas within a very short time. The finer particulate matter will remain in the atmosphere for a longer time. Gases in the vehicular emissions can also undergo chemical reactions with other gases in the atmosphere and return after a time as different compounds or solutions. Therefore, significant effort is required to understand the linkage between pollutants in atmospheric and in ground phases. The primary objective of this research is to develop mathematical relationships between pollutants in atmospheric phase and ground phase. It aims to:
