Summary
Research reveals alarmingly high serum levels of certain chemical elements in green turtles (Chelonia mydas) from Fernando de Noronha Marine National Park, Brazil, suggesting significant ocean contamination. The study analyzed 31 juvenile turtles, measuring concentrations of essential elements like calcium and selenium alongside potentially toxic metals such as lead, cadmium, and uranium. Findings indicate that some metal levels exceed minimal risk thresholds for human health, though baseline values for green turtles remain undefined, leaving their ecological impacts unclear. By correlating element concentrations with turtle size, the study hints at possible cumulative effects but underscores the need for further investigation to assess contamination risks in this UNESCO-listed marine ecosystem.
