Significant drop in SO2 levels in India in last decade: IIT KGP

There has been a significant in Sulphur Dioxide (SO2) levels in India in the last decade as compared to the previous three decades, a study conducted by IIT Kharagpur has found. The reduction in emission and concentration of SO2 has been due to environmental regulation and the adoption of effective control technologies such as 'scrubber' and 'flue gas desulphurisation', the study conducted by a team of researchers from the Centre for Oceans, Rivers, Atmosphere and Land Sciences (CORAL) of the institute stated.The study represents temporal changes in SO2 concentrations across India in the last four decades (1980-2020), an institute spokesperson said.While thermal power plants contributed 51 per cent to SO2 concentration, the construction se.....
