Organophosphate esters (OPEs) are used as flame retardants in a variety of consumer products including certain textiles. Little is known with regard to the occurrence of and dermal exposure to OPEs present in textiles/fabrics. In this study, concentrations and profiles of 20 OPEs were measured in 160 textile samples collected from the United States. The sum concentrations of 20 OPEs (∑₂₀OPE) in textiles ranged from 4.85 to 1.18 × 10⁶ ng/g (median: 228 ng/g). Significantly higher concentrations of ∑₂₀OPE were found in flame retardant-treated fabrics (n = 23; median: 8.18 × 10⁴ ng/g), especially those manufactured in the United States. Trace levels of OPEs were also detected in infant clothing. Triphenyl phosphate was the predominant compound (40.2% of total concentrations) found in flame retardant-treated textiles, followed by cresyl diphenyl phosphate (34.5%) and tris(1-chloro-2-propyl) phosphate (17.9%). The calculated dermal exposure doses in infants of major OPEs present in textiles were 5 orders of magnitude below the current reference doses. This study provides the first evidence of the occurrence of OPEs in textiles and clothing purchased in the United States.

从美国收集的婴儿服装和生纺织品中有机磷酸酯的发生和概况

有机磷酸酯（OPEs）在包括某些纺织品在内的各种消费产品中用作阻燃剂。关于存在于纺织品/织物中的OPE的发生和皮肤暴露，人们知之甚少。在这项研究中，在从美国收集的160个纺织品样品中测量了20种OPE的浓度和分布。纺织品中₂₀ OPE的总浓度（∑ ₂₀ OPE）为4.85至1.18×10 ⁶ ng / g（中位数：228 ng / g）。Σ的显著较高浓度₂₀ OPE在阻燃处理的织物（发现Ñ = 23;中位数：8.18×10 ⁴ng / g），尤其是在美国制造的产品。在婴儿服装中也检测到痕量的OPE。磷酸三苯酯是在阻燃剂处理过的纺织品中发现的主要化合物（占总浓度的40.2％），其次是磷酸甲苯基二苯酯（34.5％）和磷酸三（1-氯-2-丙基）酯（17.9％）。纺织品中主要OPE的婴儿经计算的皮肤暴露剂量比当前参考剂量低5个数量级。这项研究提供了在美国购买的纺织品和服装中出现OPE的第一个证据。
