Abstract：
Phthalates are environmental endocrine disruptors that enter the human body through a variety of pathways and harm human health. The study aimed to explore the associations between phthalate concentrations in glass window films with dormitory characteristics, occupancy activities and habits, and environmental factors, of university dormitories. We surveyed these associations and measured the indoor environmental parameters of 144 dormitories from 13 universities in Beijing. Based on the results, we further explored the factors affecting phthalate concentrations using multivariate logistic regression. The results showed that phthalate concentrations in glass window films were associated with dormitory type, duration of occupancy, daily ventilation duration, window cleaning frequency, indoor relative humidity, light intensity, temperature, and particulate matter (PM10) concentration. To date, there have only been a few studies on the factors that influence phthalate concentrations in glass window films; therefore, further study is needed. Our findings determined the influence of external factors on the different types of phthalates in window films, which helps understand indoor phthalate pollution and evaluate human exposure based on phthalate concentrations in glass window films.
摘要：
邻苯二甲酸酯是环境内分泌干扰物,通过多种途径进入人体,危害人体健康。该研究旨在探讨玻璃窗膜中邻苯二甲酸酯浓度与宿舍特征之间的关系。占用活动和习惯，和环境因素，大学宿舍。我们调查了这些关联，并测量了北京13所大学144所宿舍的室内环境参数。根据结果,我们使用多变量逻辑回归进一步探讨了影响邻苯二甲酸酯浓度的因素.结果表明，玻璃窗膜中邻苯二甲酸酯的浓度与宿舍类型有关，占用时间，每日通风持续时间，窗户清洁频率,室内相对湿度,光强度,温度,和颗粒物(PM10)浓度。迄今为止,关于影响玻璃窗膜中邻苯二甲酸酯浓度的因素只有很少的研究；因此，需要进一步研究。我们的发现确定了外部因素对窗膜中不同类型邻苯二甲酸酯的影响，这有助于了解室内邻苯二甲酸盐污染，并根据玻璃窗膜中的邻苯二甲酸盐浓度评估人体暴露。
