The Central Pollution Control Board has spoken. And it took away the crown of India’s most polluted city from Delhi. That’s right. The national capital could be the second, but its air is not the worst anymore, according to The Times of India.
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).
