DOIAbstract
Metals accumulated in the tissues of organisms inhabiting marine ecosystems generally reflect their bioavailable levels within that environment. The aim of this work was to study the presence and concentration of metals (Cd, Cr, Cu, Fe, Ni, Pb and Zn) and its bioaccumulation in liver-ink sac (n = 12) and muscle (n = 12) tissues of loliginid squids, Loligo sanpaulensis, in liver (n = 15) and muscle (n = 15) tissues of white croakers, Micropogonias furnieri, and in muscle (n = 12) tissues of franciscana dolphins, Pontoporia blainvillei, as representatives of different trophic levels of an estuarial ecosystem from the southern coast of Buenos Aires. Except for Pb, all metals were detectable in the hepatic tissues. Bioaccumulation was observed ...
