Abstract:
Objective To investigate the effects of air pollution on non-accidental death of residents in Yancheng City. Methods Data of daily air pollutions (PM2.5, PM10, NO2, SO2 and O3), average temperature, average relative humidity, and daily death information during 2014-2019 were collected. The time series semi parametric generalized additive model was used to analyze the impact of short-term exposure of air pollutants on non-accidental death in Yancheng City. Results The average daily non-accidental deaths of the entire population, respiratory system, and circulatory system were 154, 25, and 51, respectively. With the increase of 10 µg/m3 SO2, the risk of the estimated non-accidental death and respiratory death was increased by 1.19% (95%CI: 0.26%-2.12%) and 2.37% (95%CI: 0.65%-4.12 %), respectively. With the increase of 10 µ g/m3 NO2, the risk of the estimated non-accidental death, circulatory system death and respiratory death was increased by 1.50%（95%CI:0.94%-2.05%）, 1.11%（95%CI:0.08%-2.16%）, and 1.53%（95%CI:0.71%-2.36%）, respectively. With the increase of 10 µg/m3 O3, the risk of the estimated non-accidental death, circulatory system death and respiratory death was increased by 0.64%（95%CI: 0.25%-1.04%）, 0.81%（95%CI: 0.04%-1.58%）, and 0.78%（95%CI: 0.18%-1.37%）, respectively. Conclusion The short-term exposure of air pollutants affects the non-accidental death of the residents in Yancheng, and there are lag effects, of which NO2, SO2 and O3 have a greater impact.
