Content of Lead and Cadmium in Barred Hogfish, Bodianus Scrofa, Island Grouper, Mycteroperca Fusca, and Portuguese Dogfish, Centroscymnus Coelolepis, from Canary Islands, Spain

Concentration of lead and cadmium has been analyzed in Bodianus scrofa and Mycteroperca fusca captured in the Canary Islands coast. Concentration of Pb ranged from 2.53 to 306.40 and 4.97 to 792.00 microg kg(-1) respectively, while that of Cd ranged from 1.75 to 1854.50 and 6.78 to 656.00 microg kg(-1). The same metals have been analyzed in muscles, liver and skin of Centroscymnus coelolepis from Canary Islands, with contents of Pb and Cd ranged between 24.18-96.12 microg kg(-1) and 32.00-3266.58 microg kg(-1) respectively, and in the Azores Archipelago, with concentrations of Pb and Cd ranged as follow: 18.41-38.99 microg kg(-1) and 5.23-4179.87 microg kg(-1) respectively. Percentage of contribution of both metals to the PTWIs, has also been calculated for both fishes.
