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.
本研究测定了太湖水体和沉积物样品中的七种双酚类似物，并评估了潜在风险。结果表明，BPF、BPS和BPA是太湖水体样品中的主要成分。在沉积物中，BPA始终占主导地位，其次是BPF和BPS，且双酚类物质与总有机碳含量之间存在显著正相关。此外，BPF、BPS和BPA的高浓度水平分布在太湖支流（S4-S10）。目标双酚类物质的风险评估表明，综合风险商数对水生生态系统造成的生态毒性较低，饮用水潜在环境暴露对人体健康没有明显风险。
