中文摘要：

利用GC—MS对上海市玻璃表面有机膜中PAHs浓度进行了定量分析。结果表明随着楼层的增加，10层居民楼玻璃表面PAHs浓度出现先增加后减少的趋势，最高浓度出现在3层（736ng／m^2），最低在9层（346ng／m^2）：17层公寓楼PAHs浓度则是先减少后增加再减少的趋势，最高浓度出现在9层（2338ng／m^2），最低在16层（564ng／m^2）。TOC与PAHs相关性分析暗示除TOC外，玻璃表面PAHs富集可能还受控于其他因素。10层居民楼主要以3环和4环PAHs为主；而17层公寓楼则以4环为主。玻璃外表面PAHs浓度（555ng／m^2）远高于内表面（308ng／m^2）．外表面主要以Phe、Pyr、Chry、Fluo和F1为主：内外表面低环PAHs比值接近于1，高环比值基本上低于0．6。TEQ值虽然较低，但生态风险仍不能忽视。

英文摘要：

Concentration of polycyclic aromatic hydrocarbons （PAHs） in organic film on window glass surface were quantitatively analyzed by GC-MS. The results showed that with increasing floors, the density of PAHs on the residential buildings presented an increasing-decreasing trend, where the highest and lowest density appeared on the third floors and the ninth floors, respectively. While the density of PAHs of 17 floors apartment block showed a trend with first decreasing then increasing pattern, the highest and lowest density appeared on the ninth floor and the sixteenth floor, respectively. The analysis for the relations between TOC and PAHs suggests that the abundance of PAHs on the glass surface is also influenced by other factors apart from TOC. The 10 floors residential building mainly presented 3 rings and 4 rings PAHs, while the 17 floors apartment mainly presented 4 rings PAHs. The PAHs density on the outdoor glass surface was much higher than that in the indoor surface, and the outdoor glass surface mainly presented Phe, Pyr, Chry, Fluo and F1. The ratio of low rings PAHs on the indoor and outdoor surface was close to 1, while the ratio of high rings was almost less than 0.6. Although TEQ values were lower, but we still need to pay attention to the ecological risk of PAHs in organic film on glass surface.
