对2014-2015年建筑室内窗膜样品进行了6种邻苯二甲酸二酯（PAEs）的检测。线性回归分析表明，成膜质量与成膜生长时间（7 ~ 77 d）呈显著正相关。所有窗膜样品均检测到PAEs （n = 64）。在生长7 ~ 77 d的所有样品中，冬、夏窗膜样品中总6种PAEs （Sigma(6)PAEs）的中位数浓度分别为9900 ng/m(2)膜（2000 μ g/g膜）和4700 ng/m(2)膜（650 μ g/g膜）。在所分析的PAEs中，邻苯二甲酸二乙己酯（DEHP）为主要化合物（71 +/- 9.7%），其次是邻苯二甲酸二正丁酯（DBP; 20 +/- 7.4%）和邻苯二甲酸二异丁酯（DiBP; 5.1 +/- 2.2%）。PAEs之间的正相关关系表明它们的共同来源是窗膜样品。室温和相对湿度与PAEs浓度呈显著负相关（单位：ng/m(2)）。中国东北寒冷冬季通风不良显著影响窗膜中PAEs的浓度，表明冬季吸入暴露剂量较高。PAEs暴露的中位危害商（HQ）值低于1，表明通过三种暴露途径摄入PAEs被认为是可接受的。
Indoor window film samples were collected in buildings during 2014-2015 for the determination of six phthalate diesters (PAEs). Linear regression analysis suggested that the film mass was positively and significantly correlated with the duration of film growth (from 7 to 77 days). PAEs were detected in all window film samples (n = 64). For all the samples with growth days ranged from 7 to 77 days, the median concentrations of total six PAEs (Sigma(6)PAEs) in winter and summer window film samples were 9900 ng/m(2) film (2000 mu g/g film) and 4700 ng/m(2) film (650 mu g/g film), respectively. Among PAEs analyzed, di-2-ethyl-hexyl phthalate (DEHP) was the major compound (71 +/- 9.7%), followed by di-n-butyl phthalate (DBP; 20 +/- 7.4%) and diisobutyl phthalate (DiBP; 5.1 +/- 2.2%). Positive correlations among PAEs suggested their common sources in the window film samples. Room temperature and relative humidity were negatively and significantly correlated with PAEs concentations (in ng/m(2)). Poor ventilation in cold winter in Noreastern China significantly influenced the concentrations of PAEs in window film which suggested higher inhalation exposure dose in winter. The median hazard quotient (HQ) values from PAEs exposure were below 1, suggesting that the intake of PAEs via three exposure pathways was considered as acceptable.
