Abstract

This study aimed to determine dust-phase phthalate levels in 112 dormitories of 14 universities during autumn and winter, investigate their potential sources, and estimate phthalate exposure via dust ingestion. Twelve phthalates were detected, among which di-(2-ethylhexyl) phthalate (DEHP) and dicyclohexyl phthalate (DCHP) were the most abundant, followed by di-isobutyl phthalate (DiBP) and di-n-butyl phthalate (DnBP). The median concentrations and contributions of DCHP and DEHP were the highest. The contributions of di-n-octyl phthalate and di-nonyl phthalate were higher in winter than in autumn. Potential sources included iron furniture, chemical fiber textiles, clothes, and personal care products. Medium-density fiberboard furniture is a potential sink for phthalates. In two seasons, DEHP, DCHP, DiBP, and DnBP were the main phthalates ingested by college students . The median oral exposure of ten phthalates was higher in females than in males. College students have a high risk of exposure to DEHP in dormitories.

中国北京大学宿舍的尘相邻苯二甲酸盐：污染特征、潜在来源和非膳食口服暴露。

这项研究旨在测定14所大学112间宿舍在秋冬季的尘埃相邻苯二甲酸盐含量，调查其潜在来源，并估算通过摄入尘埃接触邻苯二甲酸盐的情况。研究共检测到 12 种邻苯二甲酸酯，其中含量最高的是邻苯二甲酸二（2-乙基己基）酯（DEHP）和邻苯二甲酸二环己基酯（DCHP），其次是邻苯二甲酸二异丁酯（DiBP）和邻苯二甲酸二正丁酯（DnBP）。邻苯二甲酸二异丁酯（DiBP）和邻苯二甲酸二正丁酯（DnBP）的浓度中值和贡献率最高。邻苯二甲酸二正辛酯和邻苯二甲酸二壬酯的含量在冬季高于秋季。潜在来源包括铁制家具、化纤纺织品、衣物和个人护理产品。中密度纤维板家具是邻苯二甲酸盐的潜在来源。在两个季节中，DEHP、DCHP、DiBP 和 DnBP 是大学生摄入的主要邻苯二甲酸盐。女性口腔接触 10 种邻苯二甲酸盐的中位数高于男性。大学生在宿舍中接触 DEHP 的风险很高。

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
