摘　　要：多环芳烃(Polycyclic aromatic hydrocarbons, PAHs)是一类常见的室内空气污染物,在室内空气中多以气载相(气相+颗粒相)形式存在。人体可通过呼吸和皮肤接触对气载相PAHs形成暴露,部分PAHs的人体暴露可严重危害人体健康。由于人一生中绝大部分时间在室内环境中度过,室内气载相PAHs浓度水平对人体暴露及其健康风险至关重要。本文总结了已有文献中不同国家及地区室内PAHs气载相浓度实测结果,反映了不同国家及地区建筑室内PAHs气载相浓度水平,预测我国PAHs气载相浓度现状。此外,本文还通过浓度对比,分析了国家、地区间的室内PAHs气载相浓度差异及其影响因素,包括污染源、季节变化和通风量,以期对室内气载相PAHs的控制方法提供思路。Polycyclic aromatic hydrocarbons(PAHs) are ubiquitous contaminants in indoor environments, mainly existed in the form of airborne phase(gas phase + particle phase). People can be exposed to airborne PAHs through inhalation and dermal sorption, which may lead to adverse health effects. Due to the majority of human life spent in indoor environments, indoor airborne PAHs concentration is crucial to human exposure and its health risk. In this study, we summarized the measured results of indoor PAHs airborne concentrations in different countries and regions from published papers, reflecting the indoor PAHs level and predicting the current status of indoors PAHs in China. In addition, we also analysed the differences of indoor airborne PAHs concentration between studies and their influencing factors, including pollution sources, seasonal variations and building ventilation, in order to guide the selection of controlling strategies for indoor airborne PAHs.
