随着双酚A（BPA）毒性作用的证据越来越多，其在商业产品中的应用逐渐被其他相关化合物（如双酚S（BPS））所取代。然而，对环境中BPS的发生知之甚少。在这项研究中，BPS在16种类型的纸和纸制品（n = 268）中进行了分析，包括热敏收据、纸币、传单、杂志、报纸、食品接触纸、飞机行李标签、印刷纸、厨房卷（即，纸巾）和卫生纸。所有热敏收据纸样本（n = 111）均含有浓度范围为0.0000138 - 22.0 mg/g（几何平均值：0.181 mg/g）的BPS。热敏收据纸中BPS的总体平均浓度与之前报告的同一组样本中BPA的浓度相似。热敏收据纸中BPS与BPA浓度呈显著负相关（r =-0.55，p < 0.0001）。在来自21个国家的87%的钞票样本（n = 52）中检测到BPS，浓度范围从低于定量限（LOQ）到6.26 μ g/g（几何平均值：0.029 μ g/g）。在14种其他纸产品类型（n = 105）中也发现了BPS，浓度范围为88%。据我们所知，这是第一份关于纸制品和钞票中出现BPS的报告。
As the evidence of the toxic effects of bisphenol A (BPA) grows, its application in commercial products is gradually being replaced with other related compounds, such as bisphenol S (BPS). Nevertheless, very little is known about the occurrence of BPS in the environment. In this study, BPS was analyzed in 16 types of paper and paper products (n = 268), including thermal receipts, paper currencies, flyers, magazines, newspapers, food contact papers, airplane luggage tags, printing paper, kitchen rolls (i.e., paper towels), and toilet paper. All thermal receipt paper samples (n = 111) contained BPS at concentrations ranging from 0.0000138 to 22.0 mg/g (geometric mean: 0.181 mg/g). The overall mean concentrations of BPS in thermal receipt papers were similar to the concentrations reported earlier for BPA in the same set of samples. A significant negative correlation existed between BPS and BPA concentrations in thermal receipt paper samples (r = -0.55, p < 0.0001). BPS was detected in 87% of currency bill samples (n = 52) from 21 countries, at concentrations ranging from below the limit of quantification (LOQ) to 6.26 mu g/g (geometric mean: 0.029 mu g/g). BPS also was found in 14 other paper product types (n = 105), at concentrations ranging from 88%). To our knowledge, this is the first report on the occurrence of BPS in paper products and currency bills.
