- 摘要：采集并测定了杭州市8户家庭中具有代表性的多环芳烃.测得居民室内空气中12种PAHs平均浓度为1.91-29.08μg/m3,BaP浓度为5～19ng/m3,污染十分严重.受季节及通风条件等的影响,室内空气中PAHs浓度变化较大.居民室内空气中萘主要来源于卫生球的挥发,其余PAHs主要来自燃烧,而BaP主要来自室内吸烟.
- Abstract：The concentrations of polycyclic aromatic hydrocarbons (PAHs) in indoor air of eight homes in Hangzhou were studied to identify the sources and measure the amounts of twelve PAHs in the summer and autumn The samples were collected from kitchens, living rooms, bedrooms and balconies of the homes and analyzed by HPLC The average levels of total PAHs in indoor air were between 1.91μg/m3 and 29.08μg/m3, and average concentration of the BaP was 5～19ng/m3 The PAHs pollution in the indoor air was serious The variations of season and ventilation affected the level of indoor air In the indoor air, the main source of naphthalene was mothball that was used as antiseptic, and the others were from combustion As far as the benzo(a)pyrene was concerned, the main source was the environmental tobacco smoking
