Abstract:Objective To explore the relationship of atmospheric fine particulate matter (PM2.5) pollution with death due to circulatory system diseases in residents in Shenyang City from 2014 to 2017. Methods We analyzed the characteristics of PM2.5 pollution, meteorological features and death level of circulatory system diseases in residents in Shenyang City from 2014 to 2017. The generalized linear model was used to analyze the impact of atmospheric PM2.5 on death of circulatory system diseases in the residents. Results The number of deaths caused by circulatory system diseases was positively correlated with barometricpressure and concentration levels of PM2.5, PM10, SO2 and O3-8h, with the correlation coefficients of 0.284, 0.178, 0.155, 0.244 and 0.118, respectively, but negatively correlated with temperature and NO2, with the correlation coefficients of -0.327 and -0.234, respectively. In the single-pollutant model, the ER values of deaths from circulatory system diseases in entire population, women and the elderly were 0.24% (95%CI: 0.06%-0.42%), 0.40% (95%CI: 0.13%-0.67%) and 0.23% (95%CI: 0.03%-0.43%) with rise of 10 μg/m3 for PM2.5 concentration on the day of the test. In the dual-pollutant model, PM2.5 combined with PM10 had the biggest impact on the number of deaths due to circulatory system diseases in entire population. When the mixed pollutants increased by 10 μg/m3, the ER value of deaths from circulatory system diseases in entire population was 0.48% (95%CI: 0.07%-0.89%). In the multi-pollutant model, the mixed pollutants, including PM2.5+PM10+NO2+SO2+O3, PM2.5+PM10+NO2+O3, PM2.5+ PM10+SO2+O3 and PM2.5+PM10+O3, had the biggest impact on deaths from circulatory system diseases. When the concentration of the four mixed pollutants increased by 10 μg/m3, the ER values of deaths from circulatory system diseases in entire population were 0.57% (95%CI: 0.16%-0.99%), 0.57% (95%CI: 0.16%- 0.98%), 0.57% (95%CI: 0.16%-0.99%) and 0.57% (95%CI: 0.16%-0.98%), respectively. Conclusions The mortality rate of circulatory system diseases was elevated along with the increased concentration of PM2.5. The combination of PM2.5 and other pollutants had the greatest impact on the number of deaths owing to circulatory system diseases.
