空气污染是仅次于全球死亡率的第五大风险因素。不断增长的人口规模通过需求渠道推动工业活动，快速城市化和化石燃料燃烧带来的车辆污染对清洁空气构成了严重威胁。在Prayagraj市正在研究的一些主要空气污染物是二氧化氮(NO2)、颗粒物(PM10)和二氧化硫(SO2)。城市区域污染概况。研究了Rambagh, Johnstonganj, Alopibagh, Crossing Mahalakshmi talkies和Bharat Yantra Nigam。Crossing Mahalakshmi talkial和Alopibagh地区的PM10暴露严重，暴露时间最长，在250 - 400 μ g/m3范围内。Alopibagh, Johnstonganj和Rambagh显示了二氧化氮的临界水平，表明这些地区的车辆移动较高。从趋势上看，2016年冬季初Rambagh、Johnstonganj和Alopibagh的SO2含量均在12µg/m3以上。类似的现象在2019年冬季的Bharat Yantra Nigam和Crossing Mahalakshmi电台也看到了。季风的到来往往会降低室外环境空气中的污染物含量。 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.
