The truth about air pollution in Delhi -Chandra Bhushan

There is an irony being played out in Delhi. While the national capital is reeling under one of its worst spells of air pollution, the Delhi government is bringing out a series of advertisements claiming that the pollution levels are down by 25%.

The advertisements mention that the levels of PM 2.5—particulate matter of size less than 2.5 microns—have reduced from 154 microgrammes per cubic meter (µg/m3) during 2012-2014 to 115 µg/m3 during 2016-2018. If this claim is valid, then we are on the right path, and we should continue with the current action plan to control air pollution. If it is not, then we should seriously change track and develop a new blueprint.

To understand the exact situation of pollution in the city, one has to understand the status of air pollution monitoring. Delhi has the largest number of air quality monitors in the country—47 monitoring stations, to be precise. Out of these, 10 are manual monitors, and 37 are continuous monitors. Four agencies own these monitors—the Central Pollution Control Board (CPCB) has 13 monitors, Delhi Pollution Control Committee (DPCC) has 24, India Meteorological Department (IMD) has 7 monitors, and the National Environmental Engineering Research Institute (NEERI) has 3.
