Much before air pollution emerged as a critical health and environment issue in India, we developed state-of-the-art capacities for studying air quality. Our research focusses on a range of issues, including ambient air quality and apportionment of contributing sources , indoor air quality assessment for urban and rural households, regional scale assessment, impacts on health and agriculture, and capacity building of stakeholders for better management. Our research and analyses have been taken into account by policy makers for improvements in various standards and policies.
