Little is known with regard to the occurrence of potentially toxic chemicals in textiles and clothes. In this study, 77 textiles and infant clothing pieces were analyzed for the determination of bisphenols including bisphenol A (BPA) and bisphenol S (BPS), benzophenones, bisphenol A diglycidyl ethers (BADGEs), and novolac glycidyl ethers (NOGEs). BPA and BPS occurred in 82% and 53% of the textile samples, respectively, and at mean concentrations of 366 and 15 ng/g, respectively. Benzophenone-3 (BP3) occurred in 70% of the samples at a mean concentration of 11.3 ng/g. Among 11 BADGEs and NOGEs analyzed, BFDGE was the predominant compound, with a mean concentration of 13.6 ng/g. Concentrations of target chemicals were assessed by fabric type, color, and uses. Socks contained the highest concentrations of BPA (mean: 1810 ng/g) with concentrations as high as 13 300 ng/g in a 97% polyester fabric marketed for infants. Calculated dermal exposure dose to BPA by infants via textiles was as high as 7280 pg/kg BW/d. This is the first study to report the occurrence of, and exposure to, BPA, BPS, BADGEs, and NOGEs in textiles and clothing.
目前对于纺织品和衣物中潜在有毒化学物质的存在知之甚少。在这项研究中，分析了 77 种纺织品和婴儿衣物，以测定包括双酚 A（BPA）和双酚 S（BPS）、二苯甲酮、双酚 A 二缩水甘油醚（BADGEs）和 novolac 缩水甘油醚（NOGEs）在内的双酚类物质。BPA 和 BPS 分别存在于 82%和 53%的纺织品样本中，浓度均值分别为 366 和 15ng/g。70%的样本中存在二苯甲酮-3（BP3），浓度均值为 11.3ng/g。在所分析的 11 种 BADGEs 和 NOGEs 中，BFDGE 是主要化合物，浓度均值为 13.6ng/g。根据织物类型、颜色和用途评估目标化学物质的浓度。袜子中 BPA 的浓度最高（均值：1810ng/g），在一种 97%聚酯纤维的袜子中浓度高达 13300ng/g，该纤维是为婴儿设计的。通过纺织品，婴儿皮肤接触 BPA 的剂量高达 7280pg/kg BW/d。这是首次报告在纺织品和衣物中存在 BPA、BPS、BADGEs 和 NOGEs 以及暴露于这些物质的研究。
