Aerosol Toxicity Analysis Laboratory
The Union Minister of State for Science and Technology and Earth Sciences recently inaugurated the Integrated Atmospheric Chemistry and Aerosol Toxicity Analysis Laboratory (AATAL) for the Delhi-NCR region. The facility is designed to strengthen scientific understanding of air pollution and support more targeted measures to improve air quality.
About Integrated Atmospheric Chemistry and AATAL
AATAL is a specialised facility established under Mission Mausam to identify the sources, composition and potential health effects of air pollution.
Unlike relying only on the Air Quality Index (AQI), the laboratory is intended to provide detailed information about the pollutants present in the atmosphere and their likely sources. This can help authorities design interventions based on the specific causes of pollution.
Features of AATAL
The facility can analyse a wide range of atmospheric pollutants, including gases, aerosols, PM2.5, metals, toxic elements and other particulate matter.
Its source-analysis capabilities can help distinguish pollution arising from vehicle emissions, industries, biomass and crop-residue burning, construction activities, road dust and pollutants transported from neighbouring regions.
AATAL will also study the chemical characteristics of pollutants, helping researchers better understand their potential toxicity and implications for human health.
Integration with AIRWISE
AATAL has been integrated with AIRWISE (Air Quality Warning and Integrated Decision Support System for Emissions) developed by the Indian Institute of Tropical Meteorology (IITM).
AIRWISE combines air-quality observations, forecasts and source-apportionment information. It can provide pollution forecasts at a 400-metre spatial resolution for up to 72 hours, helping authorities identify areas where air quality may deteriorate.
Significance of AATAL
The facility can support the Commission for Air Quality Management (CAQM) and other agencies in identifying pollution hotspots, selecting source-specific interventions and evaluating their effectiveness.
By combining real-time atmospheric analysis, source identification and forecasting, AATAL represents a move towards science-based and targeted air-pollution management in Delhi-NCR.
FAQs - AATAL
