The COVID-19 pandemic, which has reached 4 million global cases as of March 10, 2020, has become a worldwide problem. Turkey is one of the most affected (9 in the world) country with 139 771 cases. An intermittent curfew policy that differ for three age groups, and an intercity travel ban varying within the country have been implemented. The effects of changes in social life and industrial activity in terms of environmental pollution are not yet known. The short-term effects on PM, PM, SO, NO, NO, NO, O and CO concentrations measured at 51 air quality measurement stations (AQMS) in 11 cities in March - April period of 2020 were statistically compared with that of the previous year. While PM (9/14 AQMS) and PM (29/35 AQMS) concentrations were not significantly affected, NO (12/24 AQMS), NO (20/29 AQMS), NO (17/25 AQMS) concentrations were decreased, SO concentrations at half of the AQMSs (11/25) did not show a significant change. There were stations at which higher pollutant concentrations were measured in the study period in 2020 compared to that of 2019. Excess risks associated with PM and PM were estimated to be variable, albeit with a small difference. In conclusion, the heterogeneous actions taken in response to the COVID-19 pandemic resulted in mixed effects on ambient air quality.
截至2020年3月10日，新冠疫情全球病例已达400万，成为一个全球性问题。土耳其是受影响最严重的国家之一（全球排名第9），有139771例病例。该国实施了针对三个年龄组的间歇性宵禁政策以及国内不同地区的城际旅行禁令。社会生活和工业活动变化对环境污染的影响尚不清楚。对2020年3月至4月期间在11个城市的51个空气质量监测站（AQMS）测量的PM、PM、SO、NO、NO、NO、O和CO浓度的短期影响与上一年进行了统计比较。虽然PM（9/14个AQMS）和PM（29/35个AQMS）浓度没有受到显著影响，但NO（12/24个AQMS）、NO（20/29个AQMS）、NO（17/25个AQMS）浓度下降，一半的AQMS（11/25）的SO浓度没有显著变化。2020年研究期间，有一些站点测量到的污染物浓度高于2019年。与PM和PM相关的超额风险估计各不相同，尽管差异很小。总之，为应对新冠疫情采取的不同行动对环境空气质量产生了混合影响。
