Compared to Bisphenol A (BPA), current knowledge on the spatial distribution, potential sources and environmental risk assessment of other bisphenol analogues (BPs) remains limited. The occurrence, distribution and sources of seven BPs were investigated in the surface water and sediment from Taihu Lake and Luoma Lake, which are the Chinese shallow freshwater lakes. Because there are many industries and living areas around Taihu Lake, the total concentrations of ∑BPs were much higher than that in Luoma Lake, which is away from the industry-intensive areas. For the two lakes, BPA was still the dominant BPs in both surface water and sediment, followed by BPF and BPS. The spatial distribution and principal component analysis showed that BPs in Luoma Lake was relatively homogeneous and the potential sources were relatively simple than that in Taihu Lake. The spatial distribution of BPs in sediment of Taihu Lake indicated that ∑BPs positively correlated with the TOC content. For both Taihu Lake and Luoma Lake, the risk assessment at the sampling sites showed that no high risk in surface water and sediment (RQ < 1.0, and EEQ < 1.0 ng E/L).
与双酚 A（BPA）相比，目前对其他双酚类似物（BPs）的空间分布、潜在来源和环境风险评估的了解仍然有限。本研究调查了中国浅水湖泊太湖和骆马湖的表层水和沉积物中 7 种 BPs 的发生、分布和来源。由于太湖周围有许多工业和居民区，因此∑BPs 的总浓度远高于远离工业密集区的骆马湖。对于这两个湖泊，BPA 仍然是表层水和沉积物中占主导地位的 BPs，其次是 BPF 和 BPS。空间分布和主成分分析表明，骆马湖的 BPs 相对均匀，潜在来源比太湖简单。太湖沉积物中 BPs 的空间分布表明，∑BPs 与 TOC 含量呈正相关。对于太湖和骆马湖，采样点的风险评估表明，表层水和沉积物中没有高风险（RQ<1.0，EEQ<1.0ng E/L）。
