Associations between metabolites of aromatic compounds in bile and the occurrence of hepatic lesions in English sole (Parophrys vetulus) from Puget Sound, Washington

Statistical comparisons were made between the relative mean concentrations of metabolites of aromatic compounds in bile (as estimated by a high-performance liquid chromatography/fluorescence detection method) and idiopathic liver lesions in English sole (Parophrys vetulus) from eleven Puget Sound sites. A significant positive correlation was found between prevalences of neoplasms, foci of cellular alteration, megalocytic hepatosis and total hepatic lesions and the concentrations of metabolites of aromatic compounds. These findings provide further evidence of the putative relationship between aromatic compounds and serious idiopathic liver diseases in bottom-dwelling fish.
