The laboratory is part of the Indian Institute of Tropical Meteorology and was opened by the Union Minister of State for Science and Technology.
It measures fine particulate matter (particles smaller than a human hair) and other pollutants to determine their sources and toxicity.
Data from the lab helps the Commission for Air Quality Management plan and evaluate pollution‑control measures such as reducing vehicle emissions and limiting stubble burning.
It can analyse gases, fine particulate matter, metals, and other toxic elements to identify contributions from vehicles, industry, biomass burning, construction dust, and regional transport.
Combined with the Air Quality Warning and Integrated Decision Support System for Emissions, the lab provides real‑time data and 72‑hour forecasts to guide targeted actions under the Graded Response Action Plan.
