壬基酚（NP）及其低级乙氧基化物，壬基酚单乙氧基化物（NPE 1）和壬基酚二乙氧基化物（NPE 2），在水生环境中的总浓度可超过10 μ g/L。它们是壬基酚聚乙氧基化物（NPE）的代谢产物，已发现具有弱雌激素活性。为了评估生物累积潜力并确定这些化学品造成的潜在风险，在密歇根州不同沃茨栖息的鱼类组织中测定了NP、NPE 1、NPE 2和壬基酚三乙氧基化物（NPE 3）的浓度。该方法包括使用极限蒸汽蒸馏和同时进行的液体提取来提取样品。所有地点和物种的NP浓度范围为
Nonylphenol (NP) and its lower ethoxylates, nonylphenol monoethoxylate (NPE1) and nonylphenol diethoxylate (NPE2), can be present in aquatic environments at total concentrations of more than 10 mug/L. They are metabolites of nonylphenol polyethoxylates (NPE) and have been found to be weakly estrogenic. To evaluate bioaccumulation potential and identify potential risks posed by these chemicals, concentrations of NP, NPE1, NPE2, and nonylphenol triethoxylate (NPE3) were determined in the tissues of fish inhabiting various waters in Michigan. This method involves extraction of samples using exhaustive steam distillation with concurrent liquid extraction. Concentrations of NP among all sites and species ranged from
