Concerns have risen about air pollution in Indian cities. A recent report by the World Health Organization (WHO) states that of the 20 most polluted cities in the world, 13 are in India, with Delhi at the top.
Central Pollution Control Board (CPCB) currently monitors air quality in eight locations of Delhi – ITO, Shadipur, Dwarka, Anand Vihar, Mandir Marg, R. K. Puram, Punjabi Bagh and IHBAS. Five key pollutant levels are reported: PM2.5, SO2, NO2, CO and O3. Here information from the monitoring stations is displayed to give real-time data on 24-hour particulate levels and potential health impacts.
System of Air Quality and Weather Forecasting And Research (SAFAR) monitors real-time air pollution data in your location. Five chief pollutants are monitored: fine particulate matter (PM2.5), particulate matter of diameter 10 microns or less (PM10), NO2, CO and O3. SAFAR currently monitors air quality in ten locations of Delhi-NCR – Gurgaon, Dheerpur, Pitampura, Delhi University, Pusa, Airport (T3), Lodhi Road, Noida, Mathura Road and Aya Nagar.
