Abstract

Considering that environmental levels of cadmium have increased due to anthropogenic activity, surveillance on the concentrations of this toxic element in cetaceans and their prey is of special interest, since marine mammals appear as a choice material in the framework of ecotoxicology. Cephalopods role in the transfer of cadmium to cetaceans is well known in other regions of the planet and was also verified in Brazil. The high burden of cadmium ingested by cetaceans raise the question of a possible detrimental effect; however, as it seems that exposure has occurred during the evolution process, apparently these mammals are adapted.
