Importance de la spéciation des métaux et composés organométalliques pour une bonne évaluation des risques environnementaux en milieu marin. Cas du mercure, de I'arsenic et de l'étain

Autores: Michel, Pierre.
Methylmercury toxicity for sea-food consumers is well known long time ago. Tributyltin used as antifouling in paints is toxic at a level as low as 1 ng/l for oysters gastropod. At the opposite, organoarsenic compounds and especially arsenobetaine from fishes are much less toxic than inorganic species. Moreover, besides toxicological considerations, the biogeochemical fates of these elements need a good knowledge of the chemical forms of environmental inputs and of their behaviour in the various compartments (waters, sediments, biota). These phenomenons will be better understood by discussing typical applications.

Les teneurs en composés organochlorés dans les organismes marins de différents niveaux trophiques
Provedor de dados: 27
Autores: Vandamme, K.; Maertens, D.
Polychlorinated biphenyls (PCBs) and some organochlorine pesticides we re measured in some marine organisms of different trophic levels, sampled in the Belgian coastal waters. Because of their persistence and their lipophilic character they accumulate in lipoidal tissues, causing higher organochlorine residue levels in animals with a high adiposity. To compare the residue levels of different organisms lipid based data must be used.The concept of biological magnification controlled by mass transfers of residues through food chains is questioned because predatory fish like cod contained similar or even lower residue levels than organisms of a lower trophic levellike the peacock worm. This supports the concept that the organochlorine levels are controlled by...
