High-resolution mapping of premature mortality induced by atmospheric particulate matter in China

Air pollution, measured by the concentration of airborne particulate matter with diameter below 2.5 ?m (PM2.5), is known to cause globally adverse health effects leading premature mortality, yet high-resolution spatial distribution deaths lacking due absence detailed data for calculation mortality. Here, we mapped impact PM2.5 on mortality at high resolution in 2018 using global exposure model, then carried out statistical analysis provincial-level administrative divisions. Results show that threshold 35 ?g/m3 exceeded Xinjiang Uygur Autonomous Region, and mideastern, highly urbanized industrial regions Tianjin, Hebei, Shandong, Henan, Jiangsu, Hubei, Anhui, Shanghai. Premature China amounted 1.44 million, including 510,847 from ischemic heart disease, 471,487 cerebrovascular 220,837 chronic obstructive pulmonary 131,321 lung cancer, 103,658 lower respiratory infection. was higher men, 879,521 persons accounting 61%, than women, 558,629 persons. In divisions, were mainly concentrated North Plain, highest per capita Shandong. Our finer data, together age- sex-specific population have improved estimation impacts exposure.
