Abstract

Pollution exposure in public areas of apartment buildings has not yet been clarified. Focusing on apartment buildings, this study monitored and analyzed environmental pollutants on both sides of the corridors at different floors and heights from August to September 2023. It was found that at a distance of 9.4 m from the window, the concentration of most environmental pollutants is relatively lower across all floors (except for ozone). Specifically, these pollutants are below average levels: PM: 8.9% (14th floor) to 16.8% (1st floor), noise: 1.4% (14th floor) to 3.3% (1st floor), and TVOC: -7.1% (14th floor) to 30% (1st floor). In contrast, the ozone concentration is above average level, ranging from 47.0% (14th floor) to 84.7% (1st floor). Additionally, the research confirmed that the pollution levels on the side with open window were generally higher than on the side without open window. Monitoring of environmental pollutions at four different heights in the corridor showed that PM and TVOC pollution were more serious at heights of 0.6 m and 1.8 m, and ozone pollution was more serious at a height of 1.4 m. Specifically, these pollutants are above average levels: PM: 5.0% (14th floor) to 8.6% (1st floor), TVOC: 10.0% (14th floor) to 10.5% (1st floor), ozone: 91.5% (14th floor) to 100.3% (1st floor). This pattern of pollution distribution remained consistent across different floor levels. This study provides crucial references for improving the environmental quality of public areas in apartment buildings. The vertical distribution of different pollutants offers valuable insights for enhancing the environmental quality of other types of public spaces and advancing urban planning standards, which is of great significance for improving the health of urban residents.

公寓走廊环境污染物分布及不同高度居民污染物暴露风险差异
公寓公共区域的污染暴露尚未得到澄清。本研究以公寓楼为研究对象,于2023年8月至9月对不同楼层和高度走廊两侧的环境污染物进行了监测和分析。研究发现,在距离窗户9.4 m处,所有楼层的大多数环境污染物浓度相对较低(臭氧除外)。具体来说,这些污染物低于平均水平:PM: 8.9%(14楼)至16.8%(1楼),噪音:1.4%(14楼)至3.3%(1楼),TVOC: -7.1%(14楼)至30%(1楼)。相比之下,臭氧浓度高于平均水平,从47.0%(14楼)到84.7%(1楼)。此外,研究证实,开窗一侧的污染水平普遍高于不开窗一侧。走廊4个不同高度的环境污染监测结果显示,0.6 m和1.8 m高度PM和TVOC污染较为严重,1.4 m高度臭氧污染较为严重。具体来说,这些污染物高于平均水平:PM: 5.0%(14楼)至8.6%(1楼),TVOC: 10.0%(14楼)至10.5%(1楼),臭氧:91.5%(14楼)至100.3%(1楼)。这种污染分布模式在不同楼层之间保持一致。本研究为改善公寓楼公共区域的环境质量提供了重要的参考。不同污染物的垂直分布为提高其他类型公共空间的环境质量和提高城市规划标准提供了有价值的见解,对提高城市居民的健康水平具有重要意义。

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.
