Bisphenol compounds (BPs) are usually applied in the production of school supplies, however, little is known on the occurrence of BPs in school supplies. In this study, 15 BPs were detected in 121 samples of school supplies collected from commercial market. Among all compounds studied, BPA, BPF, and BPS were the dominant compounds in school supplies with the detection frequency of 93.15 %, 85.62 % and 82.53 %, respectively, and at median concentrations of 161, 23.64 and 14.11 ng g dw. The total concentrations of BPs varied among types of school supplies in the following order: paper (median: 1347 ng g dw) > fabric (521.4 ng g dw) > plastic (472.7 ng g dw) > rubber (352.4 ng g dw). Risk assessment of BPs in school supplies was evaluated by the estimated daily intake (EDI) via dermal absorption, and the median EDIs of ∑15 BPs were 156.78 ng d (11.27-37,042.37 ng d) and 432.75 ng d (32.44-91,624.22 ng d) for general and occupational people, respectively.
双酚化合物 (BPs) 通常应用于学校用品的生产中,但目前对于学校用品中 BPs 的存在情况知之甚少。在本研究中,从商业市场采集了 121 份学校用品样本,检测到了 15 种 BPs。在所研究的所有化合物中,BPA、BPF 和 BPS 是学校用品中主要的化合物,检出频率分别为 93.15%、85.62%和 82.53%,其浓度中位数分别为 161、23.64 和 14.11ng/g dw。BPs 的总浓度在不同类型的学校用品中依次为:纸张(中位数:1347ng/g dw)>织物(521.4ng/g dw)>塑料(472.7ng/g dw)>橡胶(352.4ng/g dw)。通过皮肤吸收估算的每日摄入量(EDI)对学校用品中 BPs 的风险进行了评估,∑15 种 BPs 的 EDI 中位数分别为 156.78ng/d(11.27-37042.37ng/d)和 432.75ng/d(32.44-91624.22ng/d),分别为一般人群和职业人群。
