The level of tiny particulate matter in the city’s air is several times the safe limit, a study of air pollution data between 2000 and 2012 says. Suspended Particulate Matter (SPM) — a mix of dust, chemicals, soot, pollen and other organic substances — can enter the lungs and causes respiratory ailments.

The study compared Environment Status Reports (ESR) from the Brihanmumbai Municipal Corporation (BMC) between 2006 to 2012 and National Environmental Engineering Research Institute (NEERI) data for the city from 2000 to 2006.

The analysis showed that SPM concentration increased from 2000, with a significant increase since 2006. As against the safe limit of 140 microgrammes per cubic metre (µg/m3), Mumbai recorded SPM levels at 1,056 µg/m3 in 2007-08 — seven times the safe limit. By 2012, levels increased to 1,853 µg/m3, 13 times the safe limit. BMC’s pollution data for 2015-16, taken from the System of Air Quality Weather Forecasting and Research (SAFAR), which collects pollution data from 10 locations in the city, recorded PM10 (pollutants smaller than 10 microns in diameter) and PM2.5 levels were above permissible limits at all locations.

The study, Changing Air Quality and its Impact: A case study of Mumbai, was published by the International Journal of Scientific Research last week. Narinder Kaur, assistant professor, Smt MMK College of Commerce and Economics, Bandra, who did the analysis, said,“Continuous emissions of harmful pollutants, especially SPM, are responsible for rising discomfort, and increasing airborne diseases in Mumbai,” said Kaur. “Open burning of municipal solid waste on the streets and landfill sites needs to be stopped immediately to improve the city’s air quality.”
