Source apportionment of suspended particulate matters in a clean area of Delhi: A note

Source apportionment of suspended particulate matters was carried out at Jawaharlal Nehru University, an extremely clean location of Delhi, using chemical mass balance receptor model. The results reveal that diesel vehicles are the major contributors followed by the industrial source. Paved road dust, gasoline vehicles and solid waste contribute 10.2%, 6.2% and 5.8%, respectively. The contribution of soil and crustal dust was minimal. The contributions of most of the sources are generally variable, except the contribution of diesel vehicles.
