Liver and kidney concentrations of vanadium in oiled seabirds after the Erika wreck

Vanadium was measured by atomic absorption spectrophotometry in the liver and kidney of several oiled seabirds that were stranded on the French Atlantic coasts after the Erika wreck and died in wildlife care Centers. Estimated averages were 30 to 77 ng g(-1) wet weight (ww) in the liver and 52 to 72 ng g(-1) wet weight in the kidney. These concentrations were not higher in oiled birds than in dead birds found later, without visible traces of petroleum on beaches not affected by the Erika pollution. Vanadium hepatic and renal concentrations do not seem to be appropriate biomarkers for recent exposure to fuel in seabirds. (C) 2004 Elsevier B.V. All rights reserved.
