Characterisation and Source Apportionment of Air Pollutants
Ravindra Khaiwal, Samantha Martin, Ranjeet S Sokhi
The air quality in urban areas is of great concern because of increasing emissions from motor vehicles. Pollutants such as fine aerosol particle (PM2.5, PM1.0, etc.), containing significant fraction of metals and organic compounds, can penetrate into lungs and, therefore, are more likely to increase respiratory and mutagenic diseases. Furthermore, these particles also play a significant role in global climate change and can be transported over long distances by prevailing winds. In order to develop strategies for the prevention, control and abatement of air pollutants improved knowledge is required on the nature, source and extent of pollution.
Together with our partner organisations, our group is investigating the sources and chemical composition of particulate matter (PM10 and PM2.5). We also focus on source apportionment of non-exhaust pollutants using tunnel studies. These details are provided in following links-
