| Abstract: | On March 19, 1984, more than 170000 gallons of oil were spilled into the Columbia River. We had recently developed analytical methods for estimating the exposure of fish to aromatic compounds by measuring the concentrations of metabolites of these contaminants in fish bile. The oil spill provided an opportunity to field test our methods in assessing the exposure of fish to petroleum aromatic compounds from the spilled oil. Our findings indicated that, within 5 days after the spill, mean concentrations of metabolites of aromatic compounds in the bile of white sturgeon (Acipenser transmontanus) captured 57 miles downstream from the spill were significantly higher than those of sturgeon caught upriver. |
