Investigating the nature and sources of non-water soluble sulfate sulfur in fine particles over a National Park in Central India
Abstract
Sulfate aerosol is ubiquitous in the lower troposphere and isan important constituent of fine particles (PM2.5).Sulfateaerosol scatters visible light and influences cloud formation, thus affecting climate. In general, water soluble sulfate sulfur(WSS) is a major contributor (if not the only one) to total particle sulfur (S). In this study, the relationships between PM2.5WSS and total S are examined. Ambient PM2.5 particles over a National Park in Bhopal, Central India were collected every other day between 01January 2012 and 31 December 2013 on various filter substrates. WSS was quantified using ion chromatography while total S was measured by ED-XRF. A preliminary examination of the relationships between WSS and S suggests the existence of significant amounts of non-WSS over the study location. Further, these relationships varied from season-to-season. This study will focus on identifying the nature and sources of non-WSS and its contribution to PM2.5 at the study location.
