Hydrocarbon residues in tissues of sea otters (`enhydra lutris`) collected following the Exxon Valdez oil spill. Marine mammal study 6-16. Exxon Valdez oil spill state/federal natural resource damage assessment. Final report
Ten moderately to heavily oiled sea otters were collected in Prince William Sound during the Exxon Valdez oil spill and up to seven tissues from each were analyzed for hydrocarbons. Aliphatic and aromatic hydrocarbons were detected in all tissues. Concentrations of aromatic hydrocarbons in fat samples were an order of magnitude higher than in other tissues. The patterns of distribution of these hydrocarbons suggested crude oil as the source of contamination. However, there was variation among oiled otters in the concentrations of individual hydrocarbons, which may be due to differing proximate causes of mortality and varying lengths of time and sea otters survived following oil exposure. The concentrations of both aliphatic and aromatic hydrocarbons in the tissues of the ten oiled sea otters generally were higher than in tissues from 7 sea otters with no external oiling that were collected from prince William Sound in 1989 and 1990, or from 12 sea otters collected from an area in southeast Alaska which had not experienced an oil spill.
