Spatial variation of multiple air pollutants and their potential contributions to all-cause, respiratory, and cardiovascular mortality across China in 2015–2016

摘要: Abstract Association of serious air pollution with adverse health effects in China has become a matter public concern. However, many studies that focused on single pollutant or city have rarely reflected the overall potential contribution to unfavorable outcomes. Therefore, our study estimated spatial variation particulate (PM2.5 and PM10) gaseous pollutants (SO2, NO2, CO, O3). Moreover, an additive approach was conducted evaluate their contributions mortality across 2015–2016 using exposure-response coefficients. The results showed cities relatively high PM2.5 PM10 concentrations were mainly distributed North Plain (NCP). average annual NCP 75.0 ± 14.7 131.2 ± 21.6 μg m−3. six ranged from 6.5% (95% confidence interval (CI): 5.4–7.5%) 25.7% CI: 22.2–28.9%) all-cause mortality, 4.7–8.3%) 24.9% 18.6–30.9%) respiratory 7.0% 5.3–8.6%) 29.5% 24.3–34.5%) cardiovascular mortality.
