摘要
采用被动采样装置采集并测定北京地区38个家庭采暖期和非采暖期室内空气中的7种气态多环芳烃(PAHs)的含量.结果表明,室内气态PAHs以2、3环组分为主,7种气态PAHs的总平均浓度为100 ng/m3左右.根据实测的PAHs浓度、不同年龄段人群室内平均停留时间及其相应的呼吸速率,计算得到室内成年人(包括老人)对7种气态PAHs的潜在总暴露速率在采暖期和非采暖期分别为66 ng/h和58 ng/h;而未成年人的潜在总暴露速率则分别为56 ng/h和50 ng/h.
heating and non-heating seasons, by the passive air samplers. The total average concentration of the gaseous PAHs was around 100 ng/m^3 , and the dominant components were those with 2 or 3 rings. The inhalation exposure of PAHs by the residents was calculated based on the concentrations of PAHs acquired, average house-staying time and respiratory rates at different ages. The calculated results indicated that, the potential total exposure rates of the seven gaseous PAHs for the adults （ including senior people） during the heating and non-heating periods were 66 ng/h and 58 ng/h, respectively; while those for juvenile people were 56 ng/h and 50 ng/h, respectively.
