目的评价2004-2008年广州市大气污染短期暴露与居民死亡风险的相关性.方法采用时间序列方法,对主要大气污染物可吸入颗粒物(PM10)、二氧化氮(NO2)和二氧化硫(SO2)与每日死亡率相关性进行Poisson回归分析.结果模型分析结果表明,通过控制年龄、性别、时间、星期几效应和气象因素,发现PM10、NO2和SO2这3种大气污染物暴露与超额死亡风险存在正相关关系.广州市3种大气污染物在过去48 h的暴露浓度每上升10 μg/m3所对应的总死亡的超额风险分别为0.94％(0.79～ 1.09)、1.55％(1.31 ～ 1.78)和1.09％(0.91 ～ 1.27).研究结果表明,大气污染物暴露与心血管系统疾病或呼吸系统疾病死亡的关联显著,对老年人和女性的影响更为显著.结论广州市主要大气污染短期暴露与居民的超额死亡风险显著相关.

Objective To study the associations between daily mortality and the status of exposure to air pollution.Methods A time-series analysis was conducted to assess the relations between acute mortality and exposure to respiratory particulate matter (PM10),sulfur-dioxide (SO2) and nitrogen dioxide (NO2) in urban residents of Guangzhou (2004-2008),using Poisson regression.Results Through controling the factors as temperature,relative humidity,age,gender and time,significant increases were observed in all-cause mortality of 0.94％ (0.79-1.09) for PM10,1.55％(1.31-1.78) for NO2,and 1.09％ (0.91-1.27) for SO2,per 10 μg/m3,when increase of the lagging 2-day average concentrations of air pollution was seen,in Guangzhou.Stronger effects of exposure to air pollution were found on cardiovascular and respiratory mortality,as well as in elderly( ≥65 years) and female population.Conclusion Our results suggested that exposure to ambient pollution was significantly associated with the increase of excess risks,on total and cardio-respiratory mortality in the residents of Guangzhou.
