This paper presents the evaluation of air quality in different districts of Haryana. Geo-spatial techniques were used to estimate gaseous and particulate pollutant's spatial and temporal variation during complete nationwide lockdown period and same month of previous year 2019 (March to May). Data of six fixed pollutants were collected from Central Pollution Control Board (CPCB). In this context, the data of air pollutants (PM, PM, O, NOx, SO, and CO) were analyzed for 2019 and 2020. The Spatio-temporal distribution of the Air Quality Index (AQI) clearly depicts difference in lockdown and unlock period. The result was showed that the air quality was very poor to satisfactory in 2019 and an improvement was observed from satisfactory to good in 2020 due to COVID-19 lockdown. On the basis of result, it will be concluded that automobile and industry are the major contributor in increase the pollutant concentration.
本研究评估了哈里亚纳邦不同地区的空气质量。利用地理空间技术，估算了在全国封锁期间和前一年（2019 年 3 月至 5 月）同月气态和颗粒污染物的时空变化。从中央污染控制委员会（CPCB）收集了六种固定污染物的数据。在这方面，分析了 2019 年和 2020 年的空气污染物（PM、PM、O、NOx、SO 和 CO）数据。空气质量指数（AQI）的时空分布清楚地表明了封锁和解锁期之间的差异。结果表明，2019 年空气质量较差到满意，由于 COVID-19 封锁，2020 年空气质量从满意改善到良好。根据结果可以得出结论，汽车和工业是导致污染物浓度增加的主要因素。
