The Consumer Product Safety Commission (CPSC) convened a Chronic Hazard Advisory Panel (CHAP) on Phthalates found in children's toys, and childcare products, and in products used by women of childbearing age. The CHAP conducted a risk assessment on phthalates and phthalate substitutes, and made recommendations to either ban, impose an interim ban, or allow the continued use of phthalates and phthalate substitutes in the above products. After a review of the literature, the evaluation included toxic end points of primary concern, biomonitoring results, extant exposure reconstruction, and epidemiological results. The health end points chosen were associated with the rat phthalate syndrome, which is characterized by malformations of the epididymis, vas deferens, seminal vesicles, prostate, external genitalia (hypospadias), and by cryptorchidism (undescended testes), retention of nipples/areolae, and demasculinization (~incomplete masculinization) of the perineum, resulting in reduced anogenital distance. Risk assessment demonstrated that some phthalates should be permanently banned, removed from the banned list, or remain interim banned. Biomonitoring and toxicology data provided the strongest basis for a mixture risk assessment. In contrast, external exposure data were the weakest and need to be upgraded for epidemiological studies and risk assessments. Such studies would focus on routes and sources. The review presents recommendations and uncertainties.
消费品安全委员会(CPSC)召集了一个慢性危害咨询小组(CHAP),该小组负责研究儿童玩具、儿童保育产品以及育龄妇女使用的产品中发现的邻苯二甲酸盐。CHAP对邻苯二甲酸盐及其替代品进行了风险评估,并就禁止、实施临时禁令或允许上述产品继续使用邻苯二甲酸盐及其替代品提出了建议。在查阅文献之后,评估内容包括主要关注的毒性终点、生物监测结果、现有暴露重建以及流行病学结果。所选择的健康终点与大鼠邻苯二甲酸盐综合征相关,其特征为附睾、输精管、精囊、前列腺、外生殖器(尿道下裂)畸形,隐睾(睾丸未降),乳头/乳晕保留,以及会阴区去男性化(~不完全男性化),导致肛门生殖器距离缩短。风险评估表明,一些邻苯二甲酸盐应被永久禁止、从禁止清单中删除或继续实施临时禁令。生物监测和毒理学数据为混合物风险评估提供了最有力的依据。相比之下,外部暴露数据最为薄弱,需要在流行病学研究和风险评估中加以完善。此类研究将聚焦于途径和来源。本综述提出了相关建议及存在的不确定性。
