OSTI ID:377350
In the weeks following the Exxon Valdez oil spill (EVOS) harbor seals, Phocavitulina richardsi, swam through oil and inhaled aromatic hydrocarbons as they breathed at the air/water interface. Concentrations of fluorescent aromatic compounds in bile clearly indicated that most seals from oiled areas had been exposed to hydrocarbons. Before the EVOS, harbor seals in Prince William Sound were declining at an average annual rate of 12% in both oiled and unoiled areas. Aerial surveys in 1989 indicated a 43% decline at oiled sites versus an 11% decline at unoiled sites. By 1992, there were still 34% fewer seals at oiled sites than before the spill.
