| الوصف: | Mercury (total and organic), cadmium, lead, copper, iron, manganese, selenium and zincconcentrations were measured in different organs of 6 different cetacean species strandedin an area of extraordinary ecological interest (Cetaceans’ Sanctuary of the MediterraneanSea) along the coast of the Ligurian Sea (North-West Mediterranean). Stable-isotopes ratiosof carbon (13C/12C) and nitrogen (15N/14N) were also measured in the muscle. A significantrelationship exists between 15N/14N, mercury concentration and the trophic level. Thedistribution of essential and non-essential trace elements was studied on several organs,and a significant relationship between selenium and mercury, with a molar ratio close to 1,was found in the cetaceans’ kidney, liver and spleen, regardless of their species. Highselenium concentrations are generally associated with a low organic to total mercury ratio.While narrow ranges of concentrations were observed for essential elements in mostorgans, mercury and selenium concentrations are characterised by a wide range ofvariation. Bio-accumulation and bio-amplification processes in cetaceans can be betterunderstood by comparing trace element concentrations with the stable-isotopes data. |
