CPCB Report - Air Pollution in Indian Cities

@ Times of India - The capital lost a dubious crown on Friday with the country's pollution watchdog saying it is not India's most polluted city, perhaps not even the second worst. But Central Pollution Control Board's (CPCB) data for the September 2015-January 2016 period clearly shows that Delhi's air is far from healthy. CPCB has published air quality indices (AQI) for 24 cities that help in comparing pollution levels at a glance with a colour code and a numerical value. In India, AQIs are determined based on the concentrations of seven pollutants, including PM2.5 (fine, respirable particles), sulphur dioxide (SO2), nitrogen dioxide (NO2) and carbon monoxide (CO).
