The accumulation of low molecular weight aromatic hydrocarbons of crude oil by coho salmon (Oncorhynchus kisutch) and starry flounder (Platichthys stellatus)


, : The accumulation of low molecular weight aromatic hydrocarbons of crude oil by coho salmon (Oncorhynchus kisutch) and starry flounder (Platichthys stellatus). Archives of Environmental Contamination and Toxicology 7(2): 237-244

Coho salmon (Oncorhynchus kisutch) and starry flounder (Platichthys stellatus) were exposed to 0.9±0.1 ppm of a water-soluble fraction (WSF) of Prudhoe Bay crude oil in flowing sea water. Both species accumulated a complex spectrum of low molecular weight aromatic hydrocarbons. Bioconcentration factors (ppm hydrocarbon based on dry weight of tissue/ ppm hydrocarbon in flow-through water) for most hydrocarbons in starry flounder muscle were substantially higher than for coho salmon muscle. After two weeks of exposure, for example, there were 17 ppm (dry weight of tissue) of C4- and C5-substituted benzenes in muscle of starry flounder (bioconcentration factor of 1,700) but only 1.5 ppm of these compounds occurred in muscle of coho salmon (bioconcentration factor of 150). Generally, alkylated aromatic hydrocarbons accumulated in tissues to a greater degree than unsubstituted derivatives. In both species, accumulations of substituted benzenes and naphthalenes in muscle increased in relation to the degree of alkylation. Complex mixtures of aromatic hydrocarbons were found in gills and liver of starry flounder. Accumulated hydrocarbons in coho salmon exposed for six weeks fell below limits of detection within a week when fish were transferred to clean water. Starry flounder exposed for two weeks retained substantial concentrations (7 to 26 ppm) of C2-C3-substituted naphthalene and C4-C5-substituted benzenes in muscle two weeks after the termination of exposure. Substantial variations were found in bioconcentration factors for individual hydrocarbons in both species. Thus the data reflect difficulties in relating specific sources of petroleum pollution to hydrocarbon profiles in tissues.
