Per- and poly-fluoroalkyl substances (PFAS) are a broad class of environmentally persistent chemicals that include thousands of potentially toxic synthetic organic molecules. Some PFAS have been shown to cause adverse health effects including decreased total cholesterol, birth weight, and reproductive success in laboratory animals; however, a lack of chronic toxicity data exists for PFAS in avian ecological receptors. The present study reports on the chronic toxicity of perfluorooctane sulfonic acid (PFOS) and a mixture of PFOS and perfluorohexane sulfonic acid (PFHxS) to northern bobwhite quail (Colinus virginianus) via oral exposure from drinking water. Female weight gain was adversely affected at an average daily intake (ADI) of 3.10 × 10-3  ± 0.15 × 10-3  mg PFOS:PFHxS (1.2:1) mixture × kg-1 body weight × d-1 . Successful liberation from the shell once pipped was adversely affected at an ADI of 2.45 × 10-3  ± 0.01 × 10-3  mg PFOS x kg-1 body weight × d-1 . These values are comparatively much lower than the current dietary avian toxicity reference value (TRV) derived from birds that were exposed via feed, suggesting the need for updated avian TRVs. Relationships between test chemical (PFOS) and test substance (PFOS:PFHxS) showed that PFOS and PFHxS have possible interacting effects in avian receptors and likely differing mechanisms of toxicity depending on chemical co-occurrence and dose. Both the single-chemical and mixture exposures produced similar and possibly additive toxicity values. Environ Toxicol Chem 2020;39:1101-1111. © 2020 SETAC.

全氟辛烷磺酸的慢性生殖毒性以及全氟辛烷磺酸和全氟己烷磺酸对北美洲白鹌鹑(Colinus virginianus)的简单混合物。

全氟烷基物质和多氟烷基物质(PFAS)是一类广泛的环境持久性化学品,其中包括数千种可能有毒的合成有机分子。研究表明,某些全氟辛烷磺酸对健康有不利影响,包括总胆固醇降低,出生体重下降和实验动物繁殖成功。然而,在禽类生态受体中缺乏关于PFAS的慢性毒性数据。本研究报告了全氟辛烷磺酸(PFOS)以及全氟辛烷磺酸和全氟己烷磺酸(PFHxS)混合物对饮用水中北方北方白鹌鹑(Colinus virginianus)的慢性毒性。女性平均日摄入量(ADI)为3.10×10-3±0.15×10-3 mg PFOS:PFHxS(1.2:1)混合物×kg-1体重×d-1时,女性体重增加受到不利影响。ADI的ADI为2.45×10-3±0.01×10-3 mg PFOS x kg-1体重×d-1时,对从壳中成功释放的不利影响。这些值相对低于当前通过饲料接触的禽类获得的饮食中禽毒性参考值(TRV),这表明需要更新的禽类TRV。测试化学物质(PFOS)与测试物质(PFOS:PFHxS)之间的关系表明,PFOS和PFHxS在禽类受体中可能具有相互作用的作用,并且取决于化学共存和剂量,其毒性机制可能不同。单一化学物和混合物的暴露均产生相似且可能附加的毒性值。Environ Toxicol Chem 2020; 39:1101-1111。©2020 SETAC。这些值相对低于当前通过饲料接触的禽类获得的饮食中禽毒性参考值(TRV),这表明需要更新的禽类TRV。测试化学物质(PFOS)与测试物质(PFOS:PFHxS)之间的关系表明,PFOS和PFHxS在禽类受体中可能具有相互作用的作用,并且取决于化学共存和剂量,其毒性机制可能不同。单一化学物和混合物的暴露均产生相似且可能附加的毒性值。Environ Toxicol Chem 2020; 39:1101-1111。©2020 SETAC。这些值相对低于当前通过饲料接触的禽类获得的饮食中禽毒性参考值(TRV),这表明需要更新的禽类TRV。测试化学物质(PFOS)与测试物质(PFOS:PFHxS)之间的关系表明,PFOS和PFHxS在禽类受体中可能具有相互作用的作用,并且取决于化学共存和剂量,其毒性机制可能不同。单一化学物和混合物的暴露均产生相似且可能附加的毒性值。Environ Toxicol Chem 2020; 39:1101-1111。©2020 SETAC。PFHxS)表明PFOS和PFHxS在禽类受体中可能具有相互作用的作用,并且取决于化学共存和剂量,其毒性机制可能不同。单一化学物和混合物的暴露均产生相似且可能附加的毒性值。Environ Toxicol Chem 2020; 39:1101-1111。©2020 SETAC。PFHxS)表明PFOS和PFHxS在禽类受体中可能具有相互作用的作用,并且取决于化学共存和剂量,其毒性机制可能不同。单一化学物和混合物的暴露均产生相似且可能附加的毒性值。Environ Toxicol Chem 2020; 39:1101-1111。©2020 SETAC。
