室内平面有机薄膜的研究对于评价有机污染物在室内环境中的迁移和去向具有重要意义。有限的研究表明，室内窗膜中多环芳烃(PAHs)的平衡状态与生长天数之间的关系。为了实现这一目标，收集了东北中国地区与膜生长天数相关的室内窗膜样品。采暖季(H季)窗膜中多环芳烃含量显著高于非采暖季(NH季)。多环芳烃的积累特征表明，多环芳烃浓度(ng/m(2)膜)随时间呈近线性增长。研究了两个季节不同积累阶段(1~11周)多环芳烃在气膜和窗膜之间的分配状况。膜中多环芳烃的平衡状态表明，目标多环芳烃的辛醇-空气分配系数(logK(OA))应近似为
The study of indoor organic film on planar surfaces has been shown to be important to assess the transport and fate of organic pollutants in indoor environments. Limited research showed the relationship between equilibrium status of polycyclic aromatic hydrocarbons (PAHs) and the growth days for indoor window films. To accomplish this goal, indoor window film samples were collected in relation to film growth days in Northeast China. PAHs were frequently detected in window films collected during heating season (H-season), with concentrations significantly higher than that of non-heating season (NH-season). Accumulation characteristics of PAH suggested that PAH concentrations (ng/m(2) film) were growing near-linearly with time. Partitioning status for PAHs between gas and window films under different accumulation stage from 1 to 11 weeks was investigated during the two seasons. The equilibrium status of PAHs in the films suggested that the octanol-air partition coefficient (logK(OA)) of the targeted PAHs should be approximately
