摘要
目的综合分析国内外大气细颗粒物(PM2.5)短期暴露与人群死亡关系的流行病学资料,以获取大气PM2.5-居民死亡的暴露-反应关系。方法在联机检索文献的基础上,对多篇文献的综合评价采用Meta分析的方法进行,定量确定PM2.5-居民每日死亡的暴露-反应关系。结果建立了居民短期接触大气PM2.5污染的暴露-反应关系,即大气PM2.5浓度每升高100μg/m3,居民死亡发生增加的百分比为12.07%(95%可信区间:8.31%～15.82%)。结论本研究建立的暴露-反应关系,可用于我国及各城市大气细颗粒物污染的健康危险度评价工作。
Objective To do the epidemiological analysis based on the data of air fine particulate matter PM2.5 and daily mortality and to estimate the exposure-response relationship. Methods Based on the online search of relevant studies with the same endpoint meta-analysis was used to do the comprehensive assessment to determine the exposure-response relationship. Results The exposure-response relationship between short-term exposure to ambient PM2.5 and the increased percentage of daily mortality was found as the concentration of air fine particulate increased a certain degree(100 μg/m3) the daily mortality of residents increased by 12.06%(95%CI 8.31%-15.82%). Conclusion The exposure-response relationship recommended in the present paper can be applied to the health risk assessment of air fine particulate matter in various cities of China.
