Abstract:
Objective:To accurately estimate the health burden and corresponding economic loss attributed to PM 2.5 pollution in the Beijing-Tianjin-Hebei (BTH) area in China in 2015. Method:By using satellite-retrieved PM 2.5 concentration data and population data provided by NASA (the spatial resolution was 1 km×1 km), this study estimated excess mortality attributed to long-term PM 2.5 exposure in BTH area in 2015 based on Global Exposure Mortality Model (GEMM). Besides, Value of Statistic Life (VSL) method was used to evaluate the corresponding health economic loss. Result:In BTH area, the population-weighted average PM 2.5 concentration during 2012-2014 was 46.25 μg/m 3, and 56.6% of total population lived in the area where annual average PM 2.5 concentration exceeded Grade Ⅱ of National Ambient Air Quality Standard in China (35 μg/m 3); The PM 2.5-related premature deaths amounted to 193.8 thousand (95 %CI: 140.9 thousand-233.3 thousand), Beijing, Tianjin, Baoding, Shijiazhuang, and Handan were the top five cities with high incidences of PM 2.5-related premature deaths; The corresponding health economic loss was about 35.934 billion (95 %CI: 26.099 billion - 43.255 billion) RMB, accounting for 0.70% (95 %CI: 0.51%-0.85%) of the area’s GDP in 2015, Beijing, Tianjin, Baoding, Shijiazhuang, and Cangzhou were the top five cities with high health economic loss. Conclusions:PM 2.5 pollution has caused severe disease and economic burden in BTH area. Its spatial distribution suggested that it is particularly necessary to develop the air pollution prevention and control policies for key cities.
