CSE report: State has highest number of stations that do not comply with PM 2.5

Only 13% of India's cities and towns have air quality monitoring stations, according to a report by the Centre for Science and Environment. Maharashtra has the highest number of monitoring stations that do not meet pollution mapping criteria, and only 12% of cities comply with national air quality standards. This leaves nearly half of the country's population outside the air quality monitoring grid. The report highlights concerns over the performance of monitoring stations, particularly for key pollutants like PM2.5 and ozone. Efforts are being made to increase the number of monitoring stations in Maharashtra and other districts.

State plans major upgrade to manual air quality monitoring network

A total of 205 new manual monitoring devices, including 123 low-volume dust samplers for measuring PM2.5, and 82 high-volume samplers for monitoring PM10 -- are proposed to be deployed in more than two dozen cities; including Mumbai, which will get nine new manual monitoring stations

Mumbai, India - November 01, 2020: Installations of low-cost sensor-based air quality monitoring equipment has been completed across 15 locations in Mumbai for the first-of-its kind study in India using this technology to accurately measure harmful pollutant concentration in the air, according to the Maharashtra Pollution Control Board (MPCB). The sensors measure ambient air quality based on light scattering technology using much smaller equipment as compared to existing air quality measuring technology. The readings from the equipment were relayed to MPCB and IIT-Kanpur servers from in Mumbai, India, on Sunday, November 01, 2020. (HT PHOTO)
