摘要

目前,对邻苯二甲酸酯(PAEs)的研究主要集中在水、土壤和空气等单个环境介质上,缺乏对中国人群在多种环境介质中暴露PAEs相关健康风险的认识。因此,通过整合2010 - 2023年已发表的PAEs暴露数据,探索全国范围内PAEs污染分布格局,评估多媒介PAEs暴露介导的健康风险,量化中国PAEs健康风险的主要影响因素。共收集了32个省的3 457个PAEs暴露数据点。结果表明,邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二异丁酯(DIBP)和邻苯二甲酸二(2-乙基己基)酯(DEHP)是所有环境介质中的主要污染物。大气、水体和土壤中PAEs的中位数浓度和含量最高的分别是浙江(120 ng·m-3)、黑龙江(6 800 ng·L-1)和广西(0.298 mg·kg-1)。风险评估结果显示,全国各省PAEs介导的非致癌风险均低于1,但黑龙江、浙江、山西三省儿童因多媒介接触PAEs而面临致癌风险。DEHP被确定为导致paes相关健康风险的主要污染物(约占71%-72%),水体和饮用水摄入是最重要的暴露媒介和途径,分别占总风险的约48%-59%和49%-59%。本研究基于已建立的PAEs暴露数据库,揭示中国人群PAEs多媒介健康风险现状,有助于制定有针对性的人群PAEs暴露健康风险降低策略。

[Concentration Distribution and Health Risk Assessment of Phthalate Esters (PAEs) in Various Environmental Media in China].

Currently, research on phthalate esters (PAEs) mainly focuses on individual environmental media, such as water, soil, and air, lacking insights into the health risks associated with PAEs exposure across multiple environmental media for the Chinese population. Therefore, by integrating the published PAEs exposure data between 2010 and 2023, we explored the distribution pattern of PAEs contamination at the national scale, assessed the health risks mediated by multi-mediated PAEs exposure, and quantified the main contributing factors to the health risks of PAEs in China. A total of 3 457 PAEs exposure data points from 32 provinces were collected. The results indicated that dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), and di(2-ethylhexyl) phthalate (DEHP) were the predominant pollutants in all environmental media. Zhejiang (120 ng·m-3), Heilongjiang (6 800 ng·L-1), and Guangxi (0.298 mg·kg-1) exhibited the highest median concentrations and contents of PAEs in the atmosphere, water bodies, and soil, respectively. The risk assessment results revealed that the non-carcinogenic risks mediated by PAEs were below 1 for all provinces in China; however, children in Heilongjiang, Zhejiang, and Shanxi provinces faced carcinogenic risks due to exposure to PAEs across multiple media. DEHP was identified as the primary pollutant contributing to PAEs-related health risks (contributing approximately 71%-72%), with water bodies and drinking water intake being the most significant exposure media and pathways, contributing approximately 48%-59% and 49%-59% of the total risk, respectively. Based on the established PAEs exposure database, this study reveals the current status of multi-mediated health risks of PAEs in the Chinese population, which can help to develop targeted strategies to reduce the health risks of PAEs exposure in the population.
