摘要: The aim of this study was to assess whether possible metal contamination in the sediment nests giant Amazon river turtle, Podocnemis expansa, could contaminate eggs and hatchlings, triggering genotoxic damage. Therefore, sediments P. expansa from two sites Brazilian were evaluated, with first being collected at Araguaia River second Crixas-Acu River. Newly hatched offspring, eggs, beaches these rivers quantification metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Pb, Zn) carried out by atomic absorption spectroscopy. All targeted found both biological samples on presenting higher concentrations Metals eggshells before nesting egg contents maternally transferred. Moreover, augmented concentration led transfer detected after (ENH) newly offspring (H). Probably relocation hatchlings frequency micronuclei their blood, 15.25‰ hatchling 10‰ animals beaches. These results indicate occurrence maternal (essential or not) testudines as well a transference effects hatchlings.
