Extensive use of bisphenol A and its analogues has caused increasing concern over the potential adverse health impacts of these chemicals. In this study, the presence and profiles of 13 bisphenols (BPs) were investigated in 52 municipal sewage sludge samples collected from 30 cities in China. Tetrabromobisphenol A was the most frequently observed analogue (geometric mean: 20.5 ng/g dw). Bisphenol A (4.69 ng/g dw), bisphenol S (3.02 ng/g dw), and bisphenol F (3.84 ng/g dw) were found with similar frequency. Other BP analogues such as tetrachlorobisphenol A, bisphenol AF, bisphenol E, and dihydroxybiphenyl were identified for the first time in sewage sludge in China. Significant correlations were found among BP concentrations, but no relationships were found with wastewater treatment plant characteristics. Profiles of the relative estradiol equivalents suggested that the estrogenic potential of BP mixtures may be associated with the occurrence and contributions of specific analogues.
双酚 A 及其类似物的广泛使用引起了人们对这些化学物质潜在健康影响的关注。本研究调查了 30 个中国城市的 52 个城市污水污泥样本中 13 种双酚（BPs）的存在和分布情况。四溴双酚 A 是最常被观察到的类似物（几何平均值：20.5ng/g dw）。双酚 A（4.69ng/g dw）、双酚 S（3.02ng/g dw）和双酚 F（3.84ng/g dw）的检出频率相似。其他 BPA 类似物，如四氯双酚 A、双酚 AF、双酚 E 和二羟基联苯，在中国首次在污水污泥中被发现。BPs 浓度之间存在显著相关性，但与污水处理厂特征无相关性。相对雌二醇当量的分布表明，BP 混合物的雌激素潜力可能与特定类似物的存在和贡献有关。
