| Popis: | Although fish readily take up hydrocarbons from the environment, substantial and rapid decreases in tissue oil concentrations occur once the animals are placed into clean water. This indicates the existence of a metabolic capacity for the removal of these lipophilic compounds from body tissues, shown in several species of fish (LEE et al. 1972, VARANASI et al. 1978). High levels of hydrocarbons are found in the bile of fish after exposure, and appear to be mainly due to the presence of metabolic products (ROUBAL et al. 1977, MELANCON & LECH 1978). Liver has also been reported to accumulate significant levels of petroleum hydrocarbons (LEE et al. 1972, KORN et al. 1976), including metabolic products (ROUBAL et al. 1977). This finding is consistent with the known role of the liver in the metabolism of petroleum hydrocarbons. The present study was undertaken to evaluate the dynamics of uptake and clearance, as well as tissue distribution, of petroleum hydrocarbons in the American eel, An guilla rostrata, following oral exposure to crude oil. Such analysis of hydrocarbon distribution and their release from tissues and body fluids may add to an understanding of the mechanisms by which fish clear petroleum hydrocarbons from their systems. Insofar as the metabolism of hydrocarbons results mainly in the conversion of the lipophilic compounds into water-soluble metabolites which can be excreted (ADAMSON 1967), a simple two-phase partitioning technique based on this principle was used to extract hydrocarbons from tissues and body fluids. |
