Bisphenol analogues (BPs) have been widely applied to industry as the substitutes for bisphenol A (BPA), which have been detected frequently in surface water, sediment, sewage and sludge. The presence of BPs in natural environment could pose risks to the aquatic ecosystem and human health. This study outlined the occurrence, toxicity of BPs in aquatic environment and manifested their potential ecological risk to the aquatic ecosystem throughout the world. As for occurrence, BPA was losing its dominance, while BPs were occupying a large part, especially for bisphenol S (BPS), bisphenol F (BPF) and bisphenol AF (BPAF). In some heavily polluted areas, BPs concentration reached µg/L in aquatic environment, which in the effluent of sewage plants was higher than that in the surface water. BPs content in sludge and sediment was more than that in the aqueous phase. All BPs other than BPS and Bisphenol P (BPP) had moderate toxicity. The current data supports that exposure to BPs may have adverse effects on dysfunction of endocrine system such as thyroid hormone concentration, enzyme activity, and even cell dysfunction, gene damage and chromosomal abnormalities. According to the risk quotient (RQ), BPF shows the highest ecological risk in China, Japan and South Korea, followed by BPA and BPS. The occurrence of bisphenols and their neurotoxicity on aquatic organisms merit further investigation.
双酚类似物（BPs）已被广泛应用于工业领域，作为双酚 A（BPA）的替代品，它们经常在地表水、沉积物、污水和污泥中被检测到。BPs 在自然环境中的存在可能对水生生态系统和人类健康构成风险。本研究概述了 BPs 在水生环境中的存在情况、毒性及其对水生生态系统的潜在生态风险。就存在情况而言，BPA 的主导地位正在丧失，而 BPs 则占据了很大一部分，特别是双酚 S（BPS）、双酚 F（BPF）和双酚 AF（BPAF）。在一些污染严重的地区，BPs 在水生环境中的浓度达到了 µg/L，而在污水处理厂的污水中，其浓度高于地表水。污泥和沉积物中的 BPs 含量高于水相。除 BPS 和双酚 P（BPP）外，所有 BPs 均具有中等毒性。目前的数据表明，接触 BPs 可能对内分泌系统功能障碍产生不利影响，如甲状腺激素浓度、酶活性，甚至细胞功能障碍、基因损伤和染色体异常。根据风险商数（RQ），BPF 在我国、日本和韩国的生态风险最高，其次是 BPA 和 BPS。双酚类物质的存在及其对水生生物的神经毒性值得进一步研究。
