新型冠状病毒病（COVID-19）继续挑战整个世界。自2019年底首次在中国发现以来，这种疾病已经从一个国家传播到另一个国家，造成许多人死亡。为防止与COVID-19相关的进一步发病率和死亡率，大多数国家在全国范围内实施封锁。虽然物理距离和封锁有助于遏制这种新型冠状病毒的传播，但却给各国带来了巨大的经济损失。由于封锁对改善各国的空气质量产生了积极影响。在目前的研究中，我们从多个角度分析了10个热带和亚热带国家，包括空气污染、对各国在COVID-19封锁期间的健康影响和经济损失的评估和评价。这些国家包括巴西、印度、伊朗、肯尼亚、马来西亚、墨西哥、巴基斯坦、秘鲁、斯里兰卡和泰国。经验证的简化气溶胶反演算法（SARA）分箱模型用于2019年1月至2020年5月所有国家直径小于2.5 μm（PM2.5）的颗粒物的中分辨率成像光谱仪（MODIS）整理的数据。PM2. 5的浓度结果显示，所有国家的空气污染在2020年封城后大幅减少。通过转换气溶胶光学厚度获得的2020年泰国的最高平均浓度为121.9微克/立方米，墨西哥的最低浓度为36.27微克/立方米。由于发现几乎所有国家的空气污染在2020年4月和5月都有所减少，因此将其与去年同期的相应值进行比较，以计算因封锁而减少的健康负担。本研究估计，由于减少空气污染外部性，累计节省约1009亿美元，约占累计经济损失4359亿美元的25%。在线版本包含补充材料，可通过10.1007/s11356-021-13813-w获得。
A novel coronavirus disease (COVID-19) continues to challenge the whole world. The disease has claimed many fatalities as it has transcended from one country to another since it was first discovered in China in late 2019. To prevent further morbidity and mortality associated with COVID-19, most of the countries initiated a countrywide lockdown. While physical distancing and lockdowns helped in curbing the spread of this novel coronavirus, it led to massive economic losses for the nations. Positive impacts have been observed due to lockdown in terms of improved air quality of the nations. In the current research, ten tropical and subtropical countries have been analysed from multiple angles, including air pollution, assessment and valuation of health impacts and economic loss of countries during COVID-19 lockdown. Countries include Brazil, India, Iran, Kenya, Malaysia, Mexico, Pakistan, Peru, Sri Lanka, and Thailand. Validated Simplified Aerosol Retrieval Algorithm (SARA) binning model is used on data collated from moderate resolution imaging spectroradiometer (MODIS) for particulate matters with a diameter of less than 2.5 μm (PM2.5) for all the countries for the month of January to May 2019 and 2020. The concentration results of PM2.5 show that air pollution has drastically reduced in 2020 post lockdown for all countries. The highest average concentration obtained by converting aerosol optical depth (AOD) for 2020 is observed for Thailand as 121.9 μg/m3 and the lowest for Mexico as 36.27 μg/m3. As air pollution is found to decrease in the April and May months of 2020 for nearly all countries, they are compared with respective previous year values for the same duration to calculate the reduced health burden due to lockdown. The present study estimates that cumulative about 100.9 Billion US$ are saved due to reduced air pollution externalities, which are about 25% of the cumulative economic loss of 435.9 Billion US$.
