In July 2000, 330 individuals of three flatfish species were collected from reference locations and nine sites surrounding the outfall of the Orange County (CA, USA) Sanitation District (OCSD) municipal wastewater discharge. Species included hornyhead turbot (Pleuronichthys verticalis), English sole (Pleuronectes vetulus), and bigmouth sole (Hippoglossina stomata). Livers of sampled animals were examined for the expression of vitellogenin (in males), cytochrome P450 1A (CYP1A), and DNA damage (comet assay). Biliary fluorescent aromatic compounds (FACs) were also measured. Comparisons with tissue and sediment contaminant residues, liver histopathology, and population estimates were assessed to determine whether relationships exist between levels of biological organization. The CYP1A results indicated exposure to planar aromatic hydrocarbons at one nearshore site. Regression analysis of all English sole CYP1A to total sediment polychlorinated biphenyls (PCBs) (r2 = 0.97; p < 0.05) indicated a significant correlation. Widespread exposure to estrogens was observed at all sites without correlation to the abundance of the three species examined. Fluorescent aromatic compounds demonstrated no correlation to CYP1A expression. Overall, histopathology and biochemical endpoints did not indicate significant adverse effects in fish at the OCSD outfall.
