Sulphur atmospheric deposition in areas with different anthropogenic loads in Belarus

This article presents some results of an investigation of sulphur atmospheric deposition in areas with different anthropogenic loads in Belarus. Through sampling and chemical analysis of precipitation, new data about sulphate concentrations in precipitation and atmospheric deposition of sulphur in different conditions, including regional background conditions, a large industrial city and a zone affected by point source of sulphur emission, were obtained. Comparison of the chemical composition of precipitation at three sampling locations has shown that the local emission of sulphur compounds has a minor influence on local sulphur deposition. This data points to the dominant role of transboundary transfer of sulphur in contamination and acidification of the environment in Belarus.
