Abstract

This study analyzed the trends in change and influencing factors based on particulate matter data from subway stations in 2019 and 2021 (before and during COVID-19). The measurements were based on subway stations on the Seoul Metro from lines 1 to 9. To confirm the changes in particulate matter concentrations before and after COVID-19, the trends of PM₁₀ and PM_2.5 concentrations in subway stations in 2019 and 2021 were analyzed. A correlation analysis was subsequently performed for a comparison of the factors influencing changes in the particulate matter concentrations. Overall, both PM₁₀ and PM_2.5 concentrations decreased during the outbreak compared to before the COVID-19 outbreak, with rates of 20.7% and 22.8%, respectively. In conclusion, the PM₁₀ and PM_2.5 concentrations in the Seoul Metro subway stations during COVID-19 were reduced. The reduction in PM₁₀ and PM_2.5, during the COVID-19 period, was the result of government policies such as telecommuting recommendations, subway congestion forecasting systems, and increased ventilation.

首尔地铁站点新冠疫情发生前和期间PM10和PM2.5浓度的影响因素

本研究基于2019年和2021年(新冠疫情前和期间)地铁站颗粒物数据，分析了变化趋势及影响因素。这些测量是基于首尔地铁1号线至9号线的地铁站进行的。为了确认新冠肺炎前后颗粒物浓度的变化，分析了2019年和2021年地铁车站PM10和PM2.5浓度的变化趋势。随后进行了相关性分析，比较了影响颗粒物浓度变化的因素。总体而言，与疫情爆发前相比，疫情期间PM10和PM2.5浓度均有所下降，降幅分别为20.7%和22.8%。由此可见，新冠疫情期间首尔地铁各车站的PM10和PM2.5浓度有所下降。在新冠肺炎期间，PM10和PM2.5的减少是政府政策的结果，如远程办公建议、地铁拥堵预测系统和增加通风。

期刊介绍： Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health. It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes. International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals. Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements. This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
