论文摘要
这项研究探讨了五种主要的空气污染物（二氧化氮（NO2），二氧化硫（SO2），颗粒物（PM2.5，PM10），一氧化碳（CO））和印度的COVID-19发生率之间的关联。在2019年和2020年获得了COVID-19确认的病例，地区和城市规模的空气污染浓度和气象变量（温度，风速，表面压力）。使用插值将基于位置的空气污染观测转换为栅格表面。据报道，迄今为止的死亡和阳性病例在孟买发现最高（436和11394），其次是艾哈迈达巴德（321和4991），浦那（129和2129），加尔各答（99和783）（99和783），印多尔（83和1699）瓦多达拉（31和400），钦奈（23和2647），博帕尔（22和652），塔那（21和1889）。与其他研究不同，这项研究并未发现在地区一级的空气污染与COVID-19的事件之间存在任何实质性关联。考虑到确认案例的数量，pM2.5的确定系数（R2）值分别为pm2.5、0.002，pM10和SO2的0.002，CO的0.001，NO2的0.0002。这表明在印度，空气污染与共同-19的事件（均为已确认的案件和死亡）之间绝对没有显着关联。也观察到死亡人数相同的关联。对于COVID-19S确认的病例，五种污染物中没有一个表现出任何具有统计学意义的关联。此外，除了风速外，气候变量与COVID-19的发生率没有任何统计学意义的关联。
This study explored the association between the five key air pollutants (Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Particulate Matter (PM2.5, PM10), and Carbon Monoxide (CO)) and COVID-19 incidences in India. The COVID-19 confirmed cases, air pollution concentration and meteorological variables (temperature, wind speed, surface pressure) for district and city scale were obtained for 2019 and 2020. The location-based air pollution observations were converted to a raster surface using interpolation. The deaths and positive cases are reported so far were found highest in Mumbai (436 and 11394), followed by Ahmedabad (321 and 4991), Pune (129 and 2129), Kolkata (99 and 783), Indore (83 and 1699), Jaipur (53 and 1111), Ujjain (42 and 201), Surat (37 and 799), Vadodara (31 and 400), Chennai (23 and 2647), Bhopal (22 and 652), Thane (21 and 1889), respectively. Unlike the other studies, this study has not found any substantial association between air pollution and COVID-19 incidences at the district level. Considering the number of confirmed cases, the coefficient of determination (R2) values estimated as 0.003 for PM2.5, 0.002 for PM10 and SO2, 0.001 for CO, and 0.0002 for NO2, respectively. This suggests an absolute no significant association between air pollution and COVID-19 incidences (both confirmed cases and death) in India. The same association was observed for the number of deaths as well. For COVID-19 confirmed cases, none of the five pollutants has exhibited any statistically significant association. Additionally, except the wind speed, the climate variables have no produced any statistically significant association with the COVID-19 incidences.
