双酚类似物广泛应用于聚碳酸酯塑料和环氧树脂的制造中，中国对这些化合物的需求和生产能力正在迅速增长。双酚A（BPA）以外的双酚类似物在水环境中的存在和分布仍然知之甚少。本研究测定了太湖、辽河流域（包括辽河和浑河）水体和沉积物中的9种双酚类似物。LR和HR的水样中总双酚（Sigma BPs）浓度要高得多。BPA和双酚S（BPS）是主要的，在TL、LR和HR沃茨中，对Sigma BPs的总贡献分别为55%、75%和75%。这表明BPA和BPS是这些地区最广泛使用和生产的双酚。在沉积物中，BPA始终占优势，其次是TL和HR沉积物中的化合物双酚F（BPF），而BPS在LR沉积物中含量较高。首次计算了某些双酚的平均实地沉积物水分配系数（log K-oc），并确定BPF、BPAP、BPA、BPAF和BPS分别为4.7、4.6、3.8、3.7和3.5 mL/g。(C)2016爱思唯尔有限公司版权所有
Bisphenol analogues are widely used in the manufacture of polycarbonate plastics and epoxy resins, and the demand and production capacity of these compounds are growing rapidly in China. The occurrence and distribution of bisphenol analogues other than bisphenol A (BPA) in the aquatic environment is still poorly understood. In this study, nine bisphenol analogues were measured in water and sediment samples from Taihu Lake (TL), Liaohe River basin, including Liaohe River (LR) and Hunhe River (HR), China. Water samples from LR and HR contained much higher total bisphenols (Sigma BPs) concentrations. BPA and bisphenol S (BPS) were predominant with a summed contribution of 55, 75, and 75% to the Sigma BPs in TL, LR, and HR waters, respectively. This suggests that BPA and BPS were the most widely used and manufactured bisphenols in these regions. In sediment, BPA was always predominant, with the next abundant compound bisphenol F (BPF) in TL and HR sediment, but BPS in LR sediment. The average field sediment water partitioning coefficients (log K-oc) were calculated for the first time for certain bisphenols and were determined to be 4.7, 4.6, 3.8, 3.7, and 3.5 mL/g for BPF, BPAP, BPA, BPAF, and BPS, respectively.
