应用


  • Pediatric respiratory health in sparsely populated areas: Research demonstrates that seasonal extreme temperatures and short-term increases in fine particulate matter significantly impact pediatric respiratory health in the intermountain western United States, underscoring the need for tailored environmental health strategies in rural settings (Landguth et al., 2024).

  • Oxidative potential of PM2.5 in urban environments: A study identifies major source categories of PM2.5 oxidative potential in wintertime Beijing, utilizing online dithiothreitol-based field measurements to enhance understanding of air pollution dynamics and health risks in heavily populated urban areas (Cheung et al., 2024).

  • Impact of fine particulate matter on COVID-19: Analysis in Bangkok during 2020-2021 links fine particulate matter and meteorological factors with the daily confirmed cases of COVID-19, offering insights into the complex interactions between air quality and public health crises (Sangkham et al., 2023).

  • Global assessment of air quality risks: A comprehensive study provides a global status and risk assessment of PM2.5 and O3 pollution based on the new WHO air quality guidelines, proposing pathways to achieve better and healthier air quality worldwide (Liu et al., 2024).

  • Personal exposure monitoring in elderly populations: This research focuses on the personal exposure of elderly residents to fine and coarse particulate matter in Hong Kong, employing exposure assessment models to evaluate individual health risks associated with urban air pollution (Lui et al., 2024).
