The estrogen pollution in the Tiaoxi River, which is the main source river for Taihu Lake, was investigated by chemical and bioassay analysis. Most estrogens species, except estrone, were not detected by the chemical analysis using liquid chromatography coupled with tandem mass spectrometry. The concentration of estrone in the samples ranged from ND (below the detection limit) to 17.25 ng/L. The estrogen activity in most water samples was also determined by the yeast estrogen screen. The 17β-estradiol equivalent in the intake of Taihu Lake was 17.60 ng/L and was present in all water samples. This study demonstrates that combining chemical and bioassay analysis is an effective way to detect environmental contamination by estrogen species. Furthermore, the results indicate that the risk of estrogen contamination in the Tiaoxi River should not be ignored.
采用化学分析和生物测定分析方法调查了太湖主要水源河 - 太滆运河的雌激素污染状况。化学分析采用液相色谱 - 串联质谱法，未检测到除雌酮以外的大多数雌激素物质。水样中雌酮的浓度范围为 ND（低于检测限）至 17.25ng/L。大多数水样中的雌激素活性也通过酵母雌激素筛选法测定。太湖进水的 17β-雌二醇当量为 17.60ng/L，存在于所有水样中。本研究表明，化学分析和生物测定分析相结合是检测环境中雌激素物质污染的有效方法。此外，研究结果表明，太滆运河的雌激素污染风险不容忽视。
