| 中文摘要 |
| 本研究对太湖表层水和沉积物中7种双酚A类似物（BPs）的浓度水平及分布特征进行了调查，并对其潜在的风险进行了评估.结果表明太湖表层水中双酚F（BPF）、双酚S（BPS）和双酚A（BPA）为主要的BPs组分；沉积物中BPA对BPs总浓度的贡献率最高，其次为BPF和BPS，且与沉积物中TOC含量具有显著的正相关；BPA、BPF和BPS在表层水和沉积物中的高浓度水平均分布在太湖入湖支流（采样点S4~S10）.风险评估表明BPs的联合毒性风险熵表现出低生态风险，且对人体不具有明显的健康风险. |
| 英文摘要 |
| 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. |
