Table 1 Summary of relevant past the characteristics of PM concentration distribution and the relationship between PM concentration and health risk.
Study area (place) | Pollutant types | Key observations | Author (year) |
|---|---|---|---|
Chile | PM2.5 | Personal PM exposure concentration and its influencing factors of commuters with different transportation modes | Suárez, L. et al. (2014) |
Iran | PM2.5/PM10 | Concentrations of annual PM exceeding the WHO air quality guideline, and an unacceptably high risk for human health | Yunesian, M. et al. (2019) |
China | PM2.5 | Short-term exposure to ambient PM2.5 was significantly associated with an increased risk of daily outpatient visits for ulcerative colitis, and related to gender and age | Duan, R. et al. (2021) |
Iran | PM10 | The average PM10 concentration was higher in summer. Higher exposure levels in female | Ahmadi, S. et al. (2021) |
Iran | PM | Most of particles were inorganic in nature, and PM may have different physicochemical characteristics in different areas | Sajjadi, S. A. et al. (2018) |
Iran | PM2.5/PM10 | The PM concentration was higher in the warm season than in the cool season, and the number of colonies increased with the increase in PM concentration | Amarloei, A. et al. (2020) |
India | PM1/PM2.5/PM10 | PM concentrations are accompanied by spatial shifts that are related to the frequency of human activity | Sahu, V. et al. (2018) |
India | PM2.5/PM10 | The number of hospitalizations for respiratory problems shows a positive correlation with PM concentrations, and PM10 has 2 times more impact on human health than PM2.5 | Gupta, A. et al. (2019) |
China | PM2.5 | The spatial distribution of PM2.5 concentration in Xi’an and the building distribution does not match | Sun, X. et al. (2020) |
