Abstract

This paper presents the evaluation of the air quality in different districts of Haryana. Geo-spatial techniques were used to estimate the spatial and temporal variation (2019-2020) of gaseous and particulate pollutants. Data of six fixed pollutants were collected from Central Pollution Control Board (CPCB). In this context, data of the air pollutant (PM10, PM2.5, O3, NOx, SO2 and CO) were analyzed seasonally for 2019 and 2020. The spatio-temporal distribution of the air quality index (AQI) clearly depicted changes indifferent meteorological and crop seasons in 2019 and 2020. The result showed that the air quality was very poor in winter and the post-monsoon seasons in 2019 and slightly improved in 2020 due to COVID 19 lockdown and satisfactory air quality was observed in the monsoon and the pre-monsoon seasons for both years. It was also observed that the air quality was poor in the rabi seasons (October to March) as compared to the kharif seasons (April to September) in 2019 and 2020. The study suggested that the air quality can be improved by the best management of straw waste instead of burning, along with reducing major pollutant sources like automobiles.

印度哈里亚纳邦季节空气质量指数的时空变化

本文对哈里亚纳邦不同地区的空气质量进行了评价。利用地理空间技术估算了2019-2020年大气和颗粒物污染物的时空变化。6种固定污染物的数据来自中央污染控制委员会(CPCB)。在此背景下，对2019年和2020年的空气污染物(PM10、PM2.5、O3、NOx、SO2和CO)数据进行了季节性分析。空气质量指数(AQI)的时空分布清晰地反映了2019年和2020年不同气象季节和作物季节的变化。结果表明，2019年冬季和季风后季节的空气质量非常差，2020年由于新冠肺炎疫情的封锁，空气质量略有改善，季风和季风前季节的空气质量都很好。还观察到，与2019年和2020年的丰收季节(4月至9月)相比，斋月季节(10月至3月)的空气质量较差。该研究表明，通过对秸秆垃圾进行最佳管理而不是焚烧，以及减少汽车等主要污染源，可以改善空气质量。
