酸盐 (PAE) 是常见的室内污染物. 这项研究量化了PAE暴露和健康风险,发现儿童面临更高的暴露,主要是通过空气和皮肤接触,导致喘等重大疾病负担.
科学领域:
- 环境健康科学 环境健康科学
- 毒理学 毒理学 毒理学
- 风险评估 风险评估
背景情况:
- 酸盐 (PAE) 是在住宅环境中发现的无处不在的室内污染物.
- 多种同时暴露途径有助于显著的健康风险.
- 现有的评估往往缺乏全面的多媒体方法.
研究的目的:
- 开发和应用一种新的多媒体甲酸盐 (PAE) 暴露评估框架.
- 量化PAE暴露剂量,相关的健康风险和住宅环境中的疾病负担.
- 确定PAE吸收的主要暴露途径和介质.
主要方法:
- 将沉的尘埃,空气,饮用水和食物矩阵集成到多媒体暴露评估框架中.
- 利用蒙特卡洛模拟来估计暴露剂量,并比较儿童与成人.
- 进行了来源分配和健康风险评估,包括非致癌和致癌影响.
- 分析疾病负担以残疾调整寿命年 (DALYs) 为单位.
主要成果:
- 二甲基甲酸盐 (DEHP) 主导着沉积尘埃,而较低分子量PAE如迪布甲酸盐 (DBP) 在室内空气中最高.
- 儿童的PAE总暴露量比成年人高1.4-2.2倍,主要通过空气和皮肤吸收.
- 对儿童的DBP,DEHP和dIBP以及成年人的DBP确定了非致癌风险.
- 丁甲甲酸对儿童和成年人构成致癌风险.
- 对PAE的暴露与因喘和皮肤炎而损失的大幅度残疾调整寿命年有关.
结论:
- 开发的多媒体框架为PAE综合健康风险评估提供了定量基础.
- 研究结果强调了与室内PAE暴露相关的重大健康风险,特别是在儿童中.
- 结果为制定针对PAE的有针对性的暴露减轻策略和监管政策提供信息.
