In China, there have been studies conducted on the relationship between PM2.5 and physical health. Gong et al. (2022) utilized the fluctuations in air pollution caused by trade shocks, specifically the global financial crisis of 2007-2008, to investigate the long-term effects of regular exposure to PM2.5. Their findings demonstrate a significant and economically meaningful increase in all-cause and cardiorespiratory mortality associated with three-year averaged pollution levels. These results are consistent with the existing literature, which indicates that higher levels of ambient air pollution contribute to higher mortality rates. Previous studies by Chen et al. (2013), He et al. (2016), and Ebenstein et al. (2017) have also examined the impact of particulate matter, including total suspended particulates (TSP) and particles smaller than ten microns (PM10), on mortality. However, the health literature suggests that PM2.5 has a more substantial adverse effect on health due to its smaller size, increased toxicity, ability to penetrate deeper into the lungs, and longer suspension in the air compared to larger particles (Pope and Dockery, 2006)
