Abstract

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 μg/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 <3.3 to 29.1 ng/g, ww and varied little among sites. NPE₁ was detectable in some samples but at concentrations less than the method detection limit (16.8 ng/g). Concentrations of NPE₂ and NPE₃ in all samples were less than their respective MDLs of 18.2 and 20.6 ng/g.
