摘　　要：介绍了室内外空气颗粒物吸入暴露的评价方法,选择PM2.5作为检测评价的对象,初步评价了上海市某区不同年龄段人员的PM2.5暴露水平。结果表明:(1)成人和老人的全年日平均PM2.5吸入暴露量均较高,并且成人的全年日平均PM2.5吸入暴露量变化曲线和儿童相似。(2)老人室内PM2.5吸入暴露量要明显高于室外,其主要原因是老人在室内时间较长。儿童和成人的室外PM2.5吸入暴露量高于室内。(3)不同人员的年平均PM2.5吸入暴露量的排序为成人>老人>儿童,其年平均PM2.5吸入暴露量分别为1.141、1.046、0.935mg。The inhalation exposure assessment method was introduced in this paper.The fine particulate matter （PM2.5） was used to assess the exposure levels of different age groups of people in Yangpu District of Shanghai.Results showed that：（1） the 24-hour average PM2.5 inhalation exposure dose of typical adult and old people was higher,and the variation of PM2.5 inhalation exposure dose of adults was similar to that of children.（2） The indoor PM2.5 inhalation exposure dose of old people was much higher than the outdoors,because they stay much of time at home.Conversely,the typical adult and child had lower exposure risk at home than outdoor.（3） The annual mean PM2.5 inhalation exposure dose of different ages people followed the order of adult＞old people＞children,their PM2.5 inhalation dose were 1.141,1.046 and 0.935 mg,respectively.
