| Abstract: | 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 μg kg−1 respectively, while that of Cd ranged from 1.75 to 1854.50 and 6.78 to 656.00 μg 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 μg kg−1 and 32.00–3266.58 μg kg−1 respectively, and in the Azores Archipelago, with concentrations of Pb and Cd ranged as follow: 18.41–38.99 μg kg−1 and 5.23–4179.87 μg kg−1 respectively. Percentage of contribution of both metals to the PTWIs, has also been calculated for both fishes. |
