本文介绍了两种ESI/LC/MS与SPE技术相结合的方法 用于分析水中新出现的内分泌干扰物。方法 雌激素/激素的报告限值为0.5纳克/升，洗涤剂的报告限值为0.5微克/升 降解产物（壬基酚和辛基酚），其他几种降解产物为0.1 ug/L 酚类内分泌干扰物。另外两种洗涤剂降解产物， 壬基酚二乙氧基化物浓度为1 ug/L，壬基酚一乙氧基化物浓度为10 ug/L， 也可以半定量。平均回收率在70-130%之间 相对标准偏差小于20%。 包括16个参考文献和表格。

Two ESI/LC/MS methods coupled with SPE technology are described in this paper for the analysis of emerging endocrine disrupting chemicals in water. The method reporting limits were 0.5 ng/L for estrogens/hormones, 0.5 ug/L for detergent degradation products (nonylphenol and octylphenol), and 0.1 ug/L for several other phenolic endocrine disrupting chemicals. Two other detergent degradation products, nonylphenol diethoxylate at 1 ug/L and nonylphenol monoethoxylate at 10 ug/L, could also be semi-quantitated. The mean recoveries were in a range of 70-130% with a relative standard deviation of less than 20%. Includes 16 references, tables.
