The distribution and bioaccumulation of steroidal and phenolic endocrine disrupting chemicals (EDCs) were studied in various tissues of wild fish species from Dianchi Lake, China. In muscle tissue, 4-tert-octylphenol, 4-cumylphenol, 4-nonlyphenol and bisphenol A were detected in fish from each sampling site, with maximal concentrations of 4.6, 4.4, 18.9 and 83.5 ng/g dry weight (dw), respectively. Steroids (estrone, 17β-estradiol 17α-ethynylestradiol and estriol) were found at lower levels (<11.3 ng/g dw) and less frequently in muscle samples. The highest concentrations of steroids and phenols were found in liver, followed by those in gill and the lowest concentration was found in muscle. The field bioconcentration factors (BCFs) of phenols were calculated in fish species ranged from 18 to 97. Moreover, the measured tissue concentrations were utilized in order to estimate water concentration of steroids (4.4-18.0 ng/L). These results showed that steroidal and phenolic EDCs were likely ubiquitous contaminants in wild fish.
研究了中国滇池野生鱼类各组织中甾醇类和酚类内分泌干扰化学物质（EDCs）的分布和生物积累情况。在肌肉组织中，从每个采样点的鱼类中检测到 4-叔辛基苯酚、4-枯基苯酚、4-壬基苯酚和双酚 A，其最大浓度分别为 4.6、4.4、18.9 和 83.5ng/g 干重（dw）。甾醇（雌酮、17β-雌二醇、17α-乙炔基雌二醇和雌三醇）的浓度较低（<11.3ng/g dw），且在肌肉样本中较少见。类固醇和酚类的最高浓度出现在肝脏中，其次是鳃，而在肌肉中浓度最低。酚类的现场生物浓缩因子（BCF）在鱼类中的范围为 18 至 97。此外，还利用测量的组织浓度来估计类固醇在水中的浓度（4.4-18.0ng/L）。这些结果表明，甾醇类和酚类 EDC 很可能是野生鱼类中普遍存在的污染物。
