In recent decades, environmental pollution has become a significant international public problem in developing and developed nations. Various regions of the USA are experiencing illnesses related to environmental pollution. This study aims to investigate the association of four environmental pollutants, including particulate matter (PM2.5), carbon monoxide (CO), Nitrogen dioxide (NO), and Ozone (O), with daily cases and deaths resulting from SARS-CoV-2 infection in five regions of the USA, Los Angeles, New Mexico, New York, Ohio, and Florida. The daily basis concentrations of PM2.5, CO, NO, and O were documented from two metrological websites. Data were obtained from the date of the appearance of the first case of (SARS-CoV-2) in the five regions of the USA from 13 March to 31 December 2020. Regionally (Los Angeles, New Mexico, New York, Ohio, and Florida), the number of cases and deaths increased significantly along with increasing levels of PM2.5, CO, NO and O ( < 0.05), respectively. The Poisson regression results further depicted that, for each 1 unit increase in PM2.5, CO, NO and O levels, the number of SARS-CoV-2 infections significantly increased by 0.1%, 14.8%, 1.1%, and 0.1%, respectively; for each 1 unit increase in CO, NO, and O levels, the number of deaths significantly increased by 4.2%, 3.4%, and 1.5%, respectively. These empirical estimates demonstrate an association between the environmental pollutants PM2.5, CO, NO, and O and SARS-CoV-2 infections, showing that they contribute to the incidence of daily cases and daily deaths in the five different regions of the USA. These findings can inform health policy decisions about combatting the COVID-19 pandemic outbreak in these USA regions and internationally by supporting a reduction in environmental pollution.
近几十年来，环境污染已成为发展中国家和发达国家的一个重大国际公共问题。美国的各个地区都出现了与环境污染有关的疾病。本研究旨在调查美国五个地区（洛杉矶、新墨西哥州、纽约、俄亥俄州和佛罗里达州）的四种环境污染物（细颗粒物 PM2.5、一氧化碳 CO、二氧化氮 NO 和臭氧 O）与每日 SARS-CoV-2 感染病例和死亡人数之间的关系。PM2.5、CO、NO 和 O 的日基础浓度从两个气象网站记录。数据从美国五个地区（洛杉矶、新墨西哥州、纽约、俄亥俄州和佛罗里达州）首次出现 SARS-CoV-2 病例之日（2020 年 3 月 13 日至 12 月 31 日）获取。在区域（洛杉矶、新墨西哥州、纽约、俄亥俄州和佛罗里达州），随着 PM2.5、CO、NO 和 O 水平的升高，病例和死亡人数呈显著增加趋势（<0.05）。泊松回归结果进一步表明，PM2.5、CO、NO 和 O 水平每增加 1 个单位，SARS-CoV-2 感染的病例数分别显著增加 0.1%、14.8%、1.1%和 0.1%；CO、NO 和 O 水平每增加 1 个单位，死亡人数分别显著增加 4.2%、3.4%和 1.5%。这些经验估计表明，PM2.5、CO、NO 和 O 等环境污染物与 SARS-CoV-2 感染之间存在关联，表明它们导致了美国五个不同地区每日病例和每日死亡人数的增加。这些发现可以为美国这些地区和国际上的卫生政策决策提供信息，以支持减少环境污染，从而抗击 COVID-19 大流行的爆发。
