| Abstract | It is widely recognized that apex predators, such as large sharks with highly migratory behavior, are particularly
vulnerable to pollution, mainly due to biomagnification processes. However, in highly impacted areas, mesopredator
sharks with resident behavior can be as vulnerable as apex sharks. In this context, this study evaluated
cadmium (Cd), mercury (Hg), lead (Pb), and rubidium (Rb) concentrations, as well as the potentially protective
effects of selenium (Se) and the behavior of two non-enzymatic biomarkers, metallothionein (MT) and reduced
glutathione (GSH), employing the Atlantic nurse shark Ginglymostoma cirratum as a study model and compared
the results with other resident benthic sharks, as well as highly mobile apex sharks. Muscle tissue samples from
28 nurse sharks opportunistically sampled from the Brazilian Amazon Coast were analyzed. Lower metal concentrations
were observed for Pb, Rb and Se in the rainy season, while statistically significant correlations between
metals were observed only between Hg and Cd and Pb and Se. Molar ratio calculations indicate potential
protective Se effects against Pb, but not against Cd and Hg. No associations between MT and the determined
metals were observed, indicating a lack of detoxification processes via the MT detoxification route. The same was
noted for GSH, indicating no induction of this primary cellular antioxidant defense. Our results indicate that
benthic/mesopredator sharks with resident behavior are, in fact, as impacted as highly mobile apex predators,
with the traditional detoxification pathways seemingly inefficient for the investigated species. Moreover,
considering the studied population and other literature data, pollution should be listed as a threat to the species
in future risk assessments. | pt_BR |
