The economic loss of public health from PM2.5 pollution in the Fenwei Plain

At present, the concentration of PM2.5 in the Fenwei Plain has become the second highest in China, ranking second to the Beijing–Tianjin–Hebei region. At the same time, China began to monitor and control the PM2.5 concentration in the Fenwei Plain, but the data indicated that the concentration of PM2.5 in the Fenwei Plain rose instead of falling. PM2.5 concentrations in 6 cities from the Fenwei Plain ranked highest among the 20 cities in 2018 in China, and PM2.5 pollution can cause some health economic loss. Based on this background, the exposure–response model is used to estimate the impact of PM2.5 pollution on the health economic loss in the Fenwei Plain, and PM2.5 concentration in 2020, 2025, and 2030 is also predicted based on the setting of three scenarios: baseline scenario, emission reduction scenario, and enhanced emission reduction scenario. Then, according to the estimated results, the paper provides suggestions for reducing public health loss in the Fenwei Plain in the future.
