中文摘要 |
目前,针对邻苯二甲酸酯(PAEs)的研究主要集中于水、土、气等单一环境介质,缺乏对中国人群多环境介质PAEs暴露健康风险的了解.因此通过整合2010~2023年间公开发表的PAEs暴露数据,探讨全国尺度下的PAEs污染分布格局,评估多介质PAEs暴露介导的健康风险,量化中国PAEs健康风险的主要贡献因子.共收集了32个省份的3 457条PAEs暴露数据,结果显示各介质中邻苯二甲酸二丁酯(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)均高于其它PAEs,是主要污染物.浙江(120 ng·m-3)、黑龙江(6 800 ng·L-1)和广西(0.298 mg·kg-1)分别是大气、水体和土壤PAEs中位浓度和含量最高的省份.风险评估结果显示,我国各省份PAEs介导的非致癌风险均小于1,但黑龙江省、浙江省和山西省儿童面临着PAEs多介质暴露导致的致癌风险.DEHP是导致PAEs健康风险的主要污染物(贡献率为71%~72%),水体和饮水摄入分别是最主要的暴露介质和暴露途径,分别贡献了总风险的48%~59%和49%~59%.基于建立的PAEs暴露数据库揭示了中国人群面临的PAEs多介质健康风险现状,有助于制定针对性策略以削减人群面临的PAEs暴露健康风险. |
英文摘要 |
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. |
