采用同时测定 39 种气态和颗粒状多环芳烃 (PAH) 的高灵敏度分析方法，测定了日本清水市室内和室外空气中的 PAH 成分。在室内和室外空气中，气态PAH浓度夏季高于冬季，颗粒状PAH浓度冬季高于夏季。相关分析表明，室内PAH成分，特别是气态PAH成分，与室外PAH成分存在显着差异。室内气态 PAH 浓度受到驱虫剂和热源的显着影响。室内颗粒物 PAH 浓度受到吸烟、房屋的年龄和类型（木材）以及室外 PAH 浓度的显着影响。通过使用基于苯并[a]芘 (BaP) 效力的毒性当量因子来估计与致癌 PAH 相关的吸入风险。室内PAH混合物的致癌性以萘为主，其次是BaP和二苯并[a,h]蒽。
A highly sensitive analytical method for the simultaneous determination of 39 gaseous and particulate polycyclic aromatic hydrocarbons (PAHs) was used to determine the PAH composition of indoor and outdoor air in Shimizu, Japan. In both indoor and outdoor air, gaseous PAH concentrations were higher in summer than in winter, whereas particulate PAH concentrations were higher in winter than in summer. Correlation analysis indicated that indoor PAH compositions, especially the gaseous PAH composition, differed significantly from outdoor PAH compositions. Gaseous PAH concentrations indoors were significantly affected by insect repellents and heating sources. Particulate PAH concentrations indoors were significantly affected by cigarette smoking, the age and type (wood) of the house, and outdoor PAH concentrations. Inhalation risk associated with carcinogenic PAHs was estimated by using toxic equivalency factors based on the potency of benzo[a]pyrene (BaP). The carcinogenicity of the indoor PAH mixture was dominated by naphthalene followed by BaP and dibenz[a,h]anthracene.
