全氟羧酸（PFCAs），包括全氟辛酸（PFOA），是对人类健康构成风险的持久性有机污染物。然而，全氟辛烷磺酸的污染源和接触途径尚未得到探讨。在这项研究中，对个人护理产品中的PFCA浓度进行了定量。在24个在其国际化妆品成分命名法（INCI）标签中列出氟化化合物（如聚氟烷基磷酸酯（PAP））的样品中，21个含有全氟化学品（15个化妆品样品中的13个，9个防晒霜样品中的8个）。化妆品中全氟乙酸的总浓度从未检测到5.9微克/克（-1）不等，防晒霜中全氟乙酸的总浓度从未检测到19微克/克（-1）不等。我们还调查了化妆品和防晒霜中的PFCAs成分。分析了市售的用PAP处理过的配合剂云母和滑石，并检测到高浓度的PFCAs（用PAP处理过的滑石的总PFCAs为2.5 μ g g（-1），用PAP处理过的云母为35.0 μ g（-1））。据我们所知，这是第一份关于含有高浓度PFCAs的PAP的最终消费品污染的报告。(C)2013爱思唯尔有限公司保留所有权利。
Perfluorinated carboxylic acids (PFCAs), including perfluorooctanoic acid (PFOA), are persistent organic pollutants that pose human health risks. However, sources of contamination and exposure pathways of PFCAs have not been explored. In this study, PFCA concentrations were quantified in personal care products. Among 24 samples that listed fluorinated compounds, such as polyfluoroalkyl phosphate esters (PAPs), in their international nomenclature of cosmetic ingredients (INCI) labels, 21 contained PFCAs (13 of 15 cosmetic samples, and 8 of 9 sunscreen samples). The concentrations of total PFCAs ranged from not detected to 5.9 mu g g(-1) for cosmetics and from not detected to 19 mu g g(-1) for sunscreens. We also investigated components of PFCAs in cosmetics and sunscreens. Commercially available compounding agents, mica and talc, which were treated with PAPs were analyzed and high concentrations of PFCAs were detected (total PFCAs 2.5 mu g g(-1) for talc treated with PAPs, 35.0 mu g g(-1) for mica treated with PAPs). To the best of our knowledge, this is the first report on contamination of end consumer products containing PAPs with high concentrations of PFCAs. (C) 2013 Elsevier Ltd. All rights reserved.
