Abstract:

Objective To analyze the impact of inhalable particles(PM10),fine particles(PM2.5) and ozone(O3) on resident mortality in a region of southeast Shanxi Province from 2020 to 2022 though the information of air pollution and resident mortality,providing scientific basis for epidemiological research on air pollutants in the area as well as the formulation of the corresponding prevention and control strategies. Methods Explore the effects of air pollutants on the health of different subgroups of population by descriptive epidemiological methods and correlation analysis,and the exposure response relationship of the impact of air pollutants on total population mortality was analyzed using a generalized additive model. Results PM2.5 and PM10 were significantly positively correlated with non-accidental mortality and cardiovascular disease mortality in male(r=0.442,0.491,both P<0.05;r=0.462,0.473,both P<0.05),and significantly positively correlated with respiratory disease mortality in female(r=0.421,0.341,both P<0.05). PM2.5 and PM10 were significantly positively correlated with cardiovascular disease mortality,non-accidental mortality and respiratory disease mortality in the elderly population aged 65 and above,and the strongest correlation was with the respiratory disease mortality(r=0.443,0.462,both P<0.05). The results of generalized additive model revealed that daily average concentrations of atmospheric pollutants PM2.5 and O3 increased by 10 μg/m3 caused the 1.782%(95%CI:0.411%-3.173%),1.482%(95%CI:0.182%-2.791%) increase in the risk of non-accidental death,and the 2.652%(95%CI:0.822%-4.513%) and 2.033%(95%CI:0.312%-3.783%) increase in the risk of cardiovascular system death. Conclusion From 2020 to 2022,the air pollution level in a region of southeast Shanxi Province has improved.The increase in PM2.5 and O3 concentrations increased the risk of non-accidental mortality death and cardiovascular disease death among residents,and O3 had a lagged effect on residents' health.
