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 (∑6PAEs) in winter and summer window film samples were 9900 ng/m(2) film (2000 μg/g film) and 4700 ng/m(2) film (650 μg/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.
2014-2015 年期间，在建筑物中采集了室内窗膜样本，用于测定六种邻苯二甲酸酯（PAEs）。线性回归分析表明，膜质量与膜生长时间（从 7 天到 77 天）呈正相关且显著相关。所有窗膜样本（n=64）均检测到 PAEs。对于生长时间在 7 至 77 天之间的所有样本，冬季和夏季窗膜样本中总六种邻苯二甲酸酯（∑6PAEs）的中位数浓度分别为 9900ng/m(2)膜（2000μg/g 膜）和 4700ng/m(2)膜（650μg/g 膜）。在所分析的邻苯二甲酸酯中，邻苯二甲酸二（2-乙基己基）酯（DEHP）是主要化合物（71±9.7%），其次是邻苯二甲酸二丁酯（DBP；20±7.4%）和邻苯二甲酸二异丁酯（DiBP；5.1±2.2%）。PAEs 之间的正相关表明它们在窗膜样本中有共同的来源。室温与相对湿度与 PAEs 浓度呈负相关且显著相关（ng/m(2)）。中国东北地区冬季通风不良，导致窗膜中 PAEs 浓度显著升高，表明冬季吸入暴露剂量较高。通过三种暴露途径接触 PAEs 的危害商（HQ）中位数均低于 1，表明摄入 PAEs 被认为是可接受的。
