BACKGROUND AND PURPOSE
In late 2019, a novel infectious disease (COVID-19) was identified in Wuhan China, which turned into a global pandemic. Countries all over the world have implemented some sort of lockdown to slow down its infection and mitigate it. This study investigated the impact of the COVID-19 pandemic on air quality during 1st January to 30th April 2020 compared to the same period in 2016-2019 in ten Iranian cities and four major cities in the world.
METHODS
In this study, the required data were collected from reliable sites. Then, using SPSS and Excel software, the data were analyzed in two intervals before and after the corona pandemic outbreak. The results are provided within tables and charts.
RESULTS
The current study showed the COVID-19 lockdown positively affected Iran's air quality. During the COVID-19 pandemic, the four-month mean air quality index (AQI) values in Tehran, Wuhan, Paris, and Rome were 76, 125, 55, and 60, respectively, which are 8 %, 22 %, 21 %, and 2 % lower than those during the corresponding period (83, 160, 70, and 61) from 2016 to 2019.
CONCLUSIONS
Although the outbreak of coronavirus has imposed devastating impacts on economy and health, it can have positive effects on air quality, according to the results.
背景与目的
2019年末，中国武汉发现一种新型传染病（COVID-19），随后演变成全球大流行。世界各国都实施了某种形式的封锁措施，以减缓其传播并减轻影响。本研究调查了2020年1月1日至4月30日期间COVID-19大流行对伊朗十个城市和世界四个主要城市空气质量的影响，并与2016 - 2019年同期进行比较。
方法
在本研究中，所需数据从可靠站点收集。然后，使用SPSS和Excel软件，对新冠疫情爆发前后两个时间段的数据进行分析。结果以表格和图表形式呈现。
结果
当前研究表明，COVID-19封锁对伊朗空气质量产生了积极影响。在COVID-19大流行期间，德黑兰、武汉、巴黎和罗马四个月的平均空气质量指数（AQI）值分别为76、125、55和60，分别比2016年至2019年同期（83、160、70和61）低8%、22%、21%和2%。
结论
根据研究结果，尽管冠状病毒的爆发对经济和健康造成了毁灭性影响，但它可能对空气质量产生积极影响。
