      • The Air Quality Index is acquired by measuring emissions of eight major pollutants present in the air: Particulate matter (PM2.5 and PM10), Ozone (O3), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Lead (Pb) and Ammonia (NH3) emissions<\/strong>.<\/li>\n\n\n\n
      • Readings are noted every hour<\/strong>. Each country has their air quality indexes based on its air quality standards.<\/li>\n<\/ul>\n\n\n\n

        • The government agencies are responsible for communicating to the public about the health hazards and how to keep a check on them.<\/li>\n\n\n\n
        • Under the\u00a0Swachh Bharat Abhiyan, the National Air Quality Index was launched in September 2014 in New Delhi to measure India\u2019s air quality index.<\/strong>\n
            \n
          • National Air Quality Index<\/strong>: Launched in 2014<\/strong> with outline \u2018One Number \u2013 One Color -One Description\u2019<\/strong> for the common man to judge the air quality within his vicinity.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • The\u00a0Central Pollution Control Board (CPCB) <\/strong>has formed an expert group of medical professionals, air quality experts, academia, advocacy groups, and SPCBs. Also, a technical study was awarded to IIT Kanpur.\n
              \n
            • In 2014, the IIT Kanpur <\/strong>and the expert group recommended an AQI scheme for India.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
            • Six cities of India- New Delhi, Kolkata, Mumbai, Pune, and Ahmedabad<\/strong> have a continuous monitoring system that records data in real-time.<\/li>\n\n\n\n
            • There are six categories of AQI:<\/strong>\n
                \n
              • Good (0-50)<\/li>\n\n\n\n
              • Satisfactory (50-100)<\/li>\n\n\n\n
              • Moderately polluted (100-200)<\/li>\n\n\n\n
              • Poor (200-300)<\/li>\n\n\n\n

              • The colour-coded AQI index<\/strong> was launched in India in 2014, and it helps the public and the government understand the condition of the air and what subsequent measures are to be taken to combat the situation, based on its severity.<\/li>\n<\/ul>\n\n\n\n
