Inequalities in PM2.5 and SO2 Exposure Health Risks in Terms of Emissions in China, 2013–2017

Exploring the health risks of diseases attributed to PM2.5 and SO2 exposure analyzing differences in their distribution over emissions can provide useful insights for decision-makers reduce premature mortality due exposure. This study used exposure-response functions, risk inequality curve (HRICU, based on Lorenz curve), coefficient (HRICO, Gini coefficient) estimate population China from 2013 2017 a full-coverage, high-precision concentration emission dataset. The was explored terms pollutant emissions. results showed that (1) mortalities cardiovascular disease (CVD) respiratory (RD) decreased by 21% 54%, respectively, 2017. (2) At national scale, HRICO value were lower than 0.10 0.20, respectively. (3) More 20% provinces had values above 0.1 or SO2. near borders generally higher PM2.5, while province with most severe inequity appeared Xinjiang Uygur Autonomous Region, Ningxia Hui Hainan Province.
