Delhi-NCR Gets India's First Air Pollution Source Lab

Delhi-NCR now has a specialised laboratory that can trace the sources of air pollution, a capability that the government says is unprecedented in the region.

Union Minister of State for Science and Technology (Independent Charge) Dr. Jitendra Singh inaugurated the Advanced Atmospheric Chemistry and Aerosol Toxicity Analysis Laboratory (AATL) on Saturday. The facility was described as the first of its kind for air pollution analysis in the Delhi-NCR area.

The ceremony was held at the Delhi branch of IITM. Officials present included Dr. T. Sreenivasa Kumar, Secretary of the Ministry of Earth Sciences, Dr. A. Suryachandra Rao, Director of IITM, and Dr. Mahapatra, Director General of the India Meteorological Department.

The laboratory is designed to help scientists separate the contributions of multiple pollution sources. These include vehicle emissions, industrial activity, biomass and crop residue burning, construction, and road dust. It will also help identify pollutants arriving from surrounding regions.

By estimating how much each source contributes, the facility aims to give authorities a clearer picture of which activities are responsible for deteriorating air quality at any given moment. This, officials said, will help them decide where interventions are likely to be most effective.

The lab is fitted with advanced instruments that analyse the chemical structure of atmospheric gases and aerosols. This covers fine particulate matter (PM2.5), metals, toxic elements, and other constituents.

The facility was set up under 'Mission Mausam', which was announced by Prime Minister Narendra Modi. The mission's goal is to strengthen the scientific understanding of atmospheric pollution and provide solid evidence for managing air quality in Delhi-NCR.

Dr. Singh explained that the region was chosen due to strong public concern over air pollution. He said the facility will move air quality assessment beyond simply reporting pollution levels. Instead, it will examine pollutant composition, sources, relative contributions, and possible health impacts. It will also deliver real-time information and early forecasts to enable prompt action.

Dr. Singh further noted that India has made significant progress in air quality forecasting and analysis over the past 10 to 12 years. He called the new facility an important milestone, as it will reveal not just the amount of pollution in the atmosphere but also its makeup and origin.
