Abstract

Total suspended particulates (TSP) and mass size distribution of aerosols were monitored by using a high-volume air sampler and a low-volume 9-stage Anderson sampler, respectively during March-April 1998 at Pune and during 5-9 January 1998 at Thiruvananthapuram. All these samples were extracted for water-and acid-soluble components using the standard extraction method. The water-soluble extracts were analysed for Cl, SO4, NO3, NH4, Na, K, Ca and Mg and acid-soluble extracts for Al, Fe, Mn, Cu, Zn, Pb, Cd, Ni and Sb. The concentration of TSP varied from 67 to 185 μg/m3 with an average of 122 μg/m3 at Pune and from 35 to 73 μg/m3 with an average of 57 μg/m3 at Thiruvananthapuram. The mass size distribution of aerosols showed bimodal distribution having one peak in coarse mode and the other in fine mode at both the locations. The results of the study are presented here.
