摘　　要：采用简化泊松回归比例危险模型,利用本研究组对国内污染物暴露-急性发病关系系数研究的meta分析结果,评价了珠江三角洲地区9个城市市区归因于可吸入颗粒物污染的健康影响,结合发病的单位经济价值数据,对健康影响进行了货币化。结果表明,珠江三角洲地区可吸入颗粒物污染对居民健康造成的影响不容忽视。对于粒径小于10μm的颗粒物(PM10)污染,参考浓度分别选取中国标准(40μg/m3)及世界卫生组织(WHO)大气质量指导值(20μg/m3),急性健康效应经济损失总量分别为1.99亿元和2.72亿元,相当于该地区2006年生产总值的0.09‰(0.07‰～0.11‰)和0.13‰(0.10‰～0.15‰)。可吸入颗粒物的急性健康效应中PM2.5的贡献在90%以上。The acute health effect due to inhalable particulate matter in the nine cities of the Pearl River Delta（PRD） was evaluated using simplified Poisson regression model.This work consulted the domestic epidemiologic studies and the metaanalysis result of exposure-response functions for health effects by the authors＇ team.Based on the unit economic value of each health effect endpoints,subsequent economic cost was estimated.Data citing was also more rigorous,this study mainly used results of domestic research and meta analysis results for exposure-response coefficients,in order to reflect current situation of PRD.The total economic cost caused by airborne particulate matter with aerodynamic diameters less than 10 μm（PM10） was estimated as approximately 0.199 billion RMB and 0.272 billion RMB for reference concentration of 40 μg /m3 and 20 μg /m3 respectively,which accounted for 0.09‰（0.07‰-0.11‰） and 0.13‰（0.10‰-0.15‰） gross domestic product（GDP） of PRD in 2006 respectively.Concerning acute health effect,PM2.5 contributed over 90% among inhalable particles.
