Trace Metals Analysis in Brown Booby (Sula leucogaster) Collected from Ilha Grande Bay, Rio de Janeiro, Brazil

A study analyzing trace metal concentrations in the brown booby (Sula leucogaster) from Ilha Grande Bay, Rio de Janeiro, Brazil, revealed relatively high levels of contamination with metals such as cadmium, zinc, copper, lead, chromium, and nickel. The average concentrations (μg.g-1 dry weight) in liver and kidney tissues were 6.32955 and 6.57136 for cadmium; 78.17409 and 96.89409 for zinc; 44.01727 and 65.20864 for copper; 41.15091 and 39.62318 for lead; 2.80091 and 4.16455 for chromium; and 9.27182 and 9.91091 for nickel. These findings are concerning due to the potential ecological impact on marine fauna in the region, highlighting the need for further investigation into the sources and effects of metal contamination.
