摘要
目的 分析菏泽市大气污染物(PM_(2.5)、SO_(2)、NO_(2)和O_(3))对居民逐日总死亡、非意外死亡、循环系统疾病死亡、呼吸系统疾病死亡的影响。方法 收集2019—2020年菏泽市逐日大气污染物(PM_(2.5)、SO_(2)、NO_(2)和O_(3))资料、气象资料和常住居民死亡资料,采用广义相加模型(GAM)的时间序列分析方法研究大气污染物与人群死亡的关联性。结果 菏泽市大气中PM_(2.5)浓度每升高10μg/m^(3),在Lag0天人群日均总死亡、非意外死亡、循环系统疾病死亡和呼吸系统疾病死亡超额风险分别为0.95%、0.96%、0.82%和0.92%;SO_(2)浓度每升高10μg/m^(3),在Lag0天呼吸系统死亡超额风险为15.33%;NO_(2)浓度每升高10μg/m^(3),在Lag0天人群日均死亡、非意外死亡、循环系统疾病死亡和呼吸系统疾病死亡超额风险分别为3.67%、3.71%、3.34%和4.24%;O_(3)浓度每升高10μg/m^(3),在Lag1天呼吸系统死亡超额风险为1.31%。结论 菏泽市大气污染物(PM_(2.5)、SO_(2)、NO_(2)、O_(3))对常住人群死亡效应存在显著影响。
Objective To analyze the effect of air pollutants(particulate matter 2.5[PM_(2.5)], sulfur dioxide[SO_(2)], nitrogen dioxide[NO_(2)]and Ozone[O_(3)]) on the daily total, non-accidental, circulatory, and respiratory mortality of inhabitants in Heze, China.Methods Daily levels of ambient pollutants(PM_(2.5), SO_(2), NO_(2) and O_(3)), meteorological data, and mortality data of residents in Heze during 2019—2020, were collected for descriptive analysis. The generalized additive model(GAM) of time series analysis was used for estimating the relationship between air pollutants and population mortality. Results With an increase of 10 μg/m^(3) of PM_(2.5), the excess risks(ERs) of the averages of daily total mortality, non-accidental mortality, circulatory mortality, and respiratory mortality on Lag0 day were 0.95%, 0.96%, 0.82%, and 0.92%, respectively. With an increase of 10 μg/m^(3) of SO_(2), the ER of respiratory mortality on Lag0 day was 15.33%. With an increase of 10 μg/m^(3) of NO_(2), the ERs of the averages of daily mortality, non-accidental mortality, circulatory mortality, and respiratory mortality on Lag0 day were 3.67%, 3.71%, 3.34%, and 4.24%, respectively. Howerver, for every 10 μg/m^(3) increase in concentration of O_(3), the ER of respiratory mortality on Lag1 was 1.31%.Conclusion Ambient pollutants(PM_(2.5), SO_(2), NO_(2) and O_(3)) have significant effect on the mortality of residents in Heze.
