摘要: High concentration of surface ozone (O-3) will cause health risks to people. In order to analyze the spatiotemporal characteristics of O-3 and assess O-3 exposure and health risks for different age groups in China, we applied multiple methods including standard deviation ellipse, spatial autocorrelation, and exposure-response functions. Results show that O-3 concentrations increased in 64.5% of areas in China from 2013 to 2018. The central plain urban agglomeration (CPU), Beijing-Tianjin-Hebei (BTH), and Yangtze River Delta (YRD) witnessed the greatest incremental rates of O-3 by 16.7%, 14.3%, and 13.1%. Spatially, the trend of O-3 shows a significant positive autocorrelation, and high trend values primarily in central and east China. The proportion of the total population exposed to high O-3 (above 160 mu g/m(3)) increased annually. Compared to 2013, the proportion of the young, adult, and old populations exposed to high O-3 increased to different extents in 2018 by 26.8%, 29.6%, and 27.2%, respectively. The extent of population exposure risk areas in China expanded in size, particularly in north and east China. The total premature respiratory mortalities attributable to long-term O-3 exposure in six urban agglomerations were about 177,000 in 2018 which has increased by 16.4% compared to that in 2013. Among different age groups, old people are more vulnerable to O-3 pollution, so we need to strengthen their relevant health protection of them.
