An Analysis of High PM2.5 Concentration Air Pollution in Subway Stations in China

Abstract

The PM2.5 air pollution in China has attracted much attention from the world. It has been proven that one of the sources of PM2.5 air pollution comes from motor vehicle exhausts. Therefore, the development and utilization of the subway is an effective way to solve air pollution issues and alleviate traffic problems. However, information about PM2.5 air pollution in the subway is mainly based on media reports and has some limitations. Therefore, this study combines the research from different fields, such as environmental science, engineering, systems science, and journalism, and uses measurement analysis to theoretical research. This article is a summary of the preliminary research content.
