[Distribution Characteristics and Potential Risk of Bisphenol Analogues in Surface Water and Sediments of Lake Taihu].

In this study, seven bisphenol analogues were measured in water and sediment samples from Taihu Lake, and potential risk was evaluated. The results showed that BPF, BPS and BPA were the predominant components in water samples from Lake Taihu. In sediment, BPA was always predominant, followed by BPF and BPS, and there was a significant positive correlation between BPs and TOC content. In addition, the high concentration levels of BPF, BPS and BPA were distributed in the tributaries of Lake Taihu(S4-S10). The risk assessment of the target BPs showed that the combined risk quotients posed a low eco-toxicity to aquatic ecosystem, and there was no appreciable risk to human health from potential environmental exposure of drinking water.
