The contamination of Sperm Whale Physeter macrocephalusand bottle‐nosed dolphin Tursiops truncatusby lead is less than detection limit, insignificant by cadmium and nickel, not very high by copper and quite high by zinc. On the other hand, the concentration of mercury, very low for Sperm Whale, is very high for bottle‐nosed dolphin.The pollution of Physeter macrocephalusis significantly lower than that of dolphin Stenella coeruleoalbaand probably that of other species of cetaceans living near the coast; this might be due to its pelagic life and its diet.The mercury pollution of Tursiops truncatus(especially that of one of the two subjects analyzed) is quite similar to that of Stenella coeruleoalba. This might be due to the fact that Tursiops truncatuscan live in the open sea just as well as close to the seashore. |
