Union government has launched the National Air Quality Index (AQI) for monitoring the quality of air in major urban centres across the country on a real-time basis and enhancing public awareness for taking mitigative action. The AQI has been at present launched for 10 cities — Delhi, Agra, Kanpur, Lucknow, Varanasi, Faridabad, Ahmadabad, Chennai, Bangalore and Hyderabad. The index considers eight pollutants — PM10, PM2.5, NO2, SO2, CO, O3, NH3 and Pb). The likely health implications of the six categories would also be provided with a colour code. Reference
