论文摘要
空气污染是对人类健康的威胁，特别是因为它加剧了呼吸系统疾病。意大利武汉和意大利伦巴第的Covid-19-19-爆发与高水平的空气污染引起人们对颗粒物质和其他污染物在感染中的潜在作用以及新肺部疾病更为严重的结果的关注。空气污染和共同19的结果都是由人类流动性和经济活动驱动的，导致回归估算中的虚假相关性。我们使用来自比利时，巴西，德国，意大利，英国和美国的地区级面板数据，以估计空气污染水平每日变化对COVID-19-19的感染和死亡的影响。使用热反演产生的空气污染的随机变化，我们排除了流动性和经济活动的变化正在推动结果。我们发现，在前三周中，空气污染水平1％导致每周增加1.5％。在四个星期内，空气污染的1％症状导致COVID-19死亡增加5.1％。这些结果表明，减少空气污染的短期措施可以帮助减轻病毒的健康损害。
Air pollution is a threat to human health, in particular since it aggravates respiratory diseases. Early COVID-19 outbreaks in Wuhan, China and Lombardy, Italy coincided with high levels of air pollution drawing attention to a potential role of particulate matter and other pollutants in infections and more severe outcomes of the new lung disease. Both air pollution and COVID-19 outcomes are driven by human mobility and economic activity leading to spurious correlations in regression estimates. We use district-level panel data from Belgium, Brazil, Germany, Italy, the UK, and the US to estimate the impact of daily variation in air pollution levels on COVID-19 infections and deaths. Using random variation in air pollution generated by thermal inversions, we rule out that changes in mobility and economic activity are driving the results. We find that a 1%-increase in air pollution levels over the three preceding weeks leads to a 1.5% increase in weekly cases. A 1%-increase in air pollution over four weeks leads to 5.1% more COVID-19 deaths. These results indicate that short-term measures to reduce air pollution can help mitigate the health damages of the virus.
