上海市A城区大气PM_(10)、PM_(2.5)污染与居民日死亡数的相关分析

Study on relationship between ambient PM_( 10),PM_(2.5) pollution and daily mortality in a district in Shanghai

目的 探讨大气颗粒物污染对人群健康的影响。方法 采用Poisson广义相加模型对上海市A城区大气PM1 0 、PM2 5的日平均污染浓度与居民日死亡数进行相关回归分析 ,并控制了时间长期趋势、气象、季节、一周日效应混杂因素的影响。结果 当大气PM1 0 、PM2 5浓度上升 10 μg m3时 ,总死亡数分别上升 0 5 3%(0 2 2 %～ 0 85 % )、0 85 % (0 32 %～ 1 39% )。结论 大气粗细颗粒物污染具有潜在的急性人群健康危害。

Objective Explore the adverse impact of ambient particulate matter pollution on human health.Methods Generalized additive model(GAM) extended poisson regression was used to examined the exposure-response relationship between ambient PM 10, PM 2.5 pollution and daily mortality in a district in Shanghai. Regression analyses was used for analysis with adjustment for controlling time trends, weather, season, the day of the week. Results A 10μg/m+3 increase in PM 10, and PM 2.5 were associated with 0.53%(0.22%-0.85%), 0.85%(0.32%-1.39%) increase in total daily mortality respectively.Conclusion Ambient particulate pollution has potential acute adverse health effects on human.
