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.

The surging particulate matter (PM) from stubble burning only adds to Delhi's woes as it already has the dubious distinction of being a non-attainment city, primarily because PM concentration has not stayed within the limits of the national ambient air quality standards in the last five years. The most worrisome aspect is that the burgeoning city is home to nearly 19 million people, and high exposure to poor air quality every year makes more and more people sick and vulnerable.
