Bridge between Precision PM2.5 Exposure Study and Healthy Life of Citizens: A Mini-review

Air pollution poses a significant health risk to residents. To better address the health and well-being needs of the population, more in-depth research on air pollution is essential. This article focuses on key issues in refined PM2.5 exposure research, including the development of high-precision PM2.5 distribution maps, the estimation of indoor PM2.5 exposure, and the variations in health risks among different populations exposed to PM2.5. Refined PM2.5 exposure research primarily involves three factors: the creation of accurate PM2.5 maps, the assessment of indoor PM2.5 exposure, and the categorization of different population groups. By thoroughly analyzing existing research, this article proposes future research directions and optimization strategies, with the goal of providing valuable insights for furthering refined PM2.5 exposure studies.
