Abstract
In this present paper we studied about the analysis, concentration, and correlation of particulate matter. Concentration of a dozen of elements namely Cd, Cr, Cu, Mn, Ni, Pb, Zn, Fe, Ca, K, Na and Al were quantified. Sampling was done on nuclear polycabonate filters. For principal component analysis (PCA) of elements and mass concentration data, three main sources were identified as PM2.5 and PM2.5-10 concentration. They are resuspended crustal dust, industrial emissions and vehicles exhaust. The effect of weather conditions was also studied. It was found that pollution in summer was higher than those in winter. The PM2.5/PM2.5-10 ratio in summer was found to be in the range of 0.35 - 0.9 whereas the same ratio in winter was 0.20 - 0.50.
