在中国北方典型城市太原，采集了126名健康志愿者在采暖期和非采暖期的多环芳烃（PAHs）吸入暴露样品，并进行了分析。城市居民采暖季和非采暖季PAH暴露水平分别为690（540-1051）和404（266-544）ng/m3，农村居民分别为770（504-1071）和312（201-412）ng/m3。因此，农村居民暴露于较低的PAH污染相比，城市居民在非采暖季节。在供暖季节，城市和农村居民的个人PAH吸入暴露水平相当，部分原因是农村地区家庭烹饪和取暖的住宅固体燃料消耗率很高。太原市农村和城市居民因多环芳烃暴露而导致的终生癌症风险增量分别为3.36 × 10（-5）和2.39 × 10（-5），明显高于全国文献报道的平均水平，表明多环芳烃污染控制对保护人体健康的迫切性。
Personal inhalation exposure samples were collected and analyzed for polycyclic aromatic hydrocarbons (PAHs) for 126 selected volunteers during heating and non-heating seasons in a typical northern Chinese city, Taiyuan. Measured personal PAH exposure levels for the urban residents in the heating and non-heating seasons were 690 (540-1051) and 404 (266-544) ng/m(3), respectively, while, for the rural residents, they were 770 (504-1071) and 312 (201-412) ng/m(3), respectively. Thus, rural residents are exposed to lower PAH contamination in comparison with the urban residents in the non-heating seasons. In the heating season, personal PAH inhalation exposure levels were comparable between the urban and rural residents, in part owing to the large rate of residential solid fuel consumption in the rural area for household cooking and heating. The estimated incremental lifetime cancer risks (ILCR) due to PAH exposure in Taiyuan were 3.36x10(-5) and 2.39x10(-5) for the rural and urban residents, respectively, significantly higher than the literature-reported national average level, suggesting an urgent need of PAH pollution control to protect human health.
