Overall air quality is in critical zone at Alopibagh for 45 per cent of the time period followed by Johnstonganj. Crossing Mahalakshmi talkies and Bharat Yantra Nigamshows critical air quality for more than 60 per cent of the time period which calls for urgent action to prevent them from entering the critical zone. Overall air quality of Prayagraj is range bound with air pollutants improve during the monsoon season. However, improvement in air quality has reduced in the last two years as fall in air pollutants is less in 2018 and 2019 monsoon compared to previous two years. The findings of the paper will help the administration, municipal corporation and various stake holders of the city to take targeted measures locality wise towards pollution control depending upon pollutants concentration and exposure area – wise. It will also raise public awareness about pollutant levels in their area.}, number = {74}, doi = {10.12944/CWE.15.3.19} }
