Abstract

Trace elements are considered toxic in high levels for human and animal organisms. In aquatic environment, some elements can form organic compounds and tend to bioaccumulate in organisms tissues. Bivalve mollusks participate on the metallic contaminants dynamics in aquatic environment due to capacity in concentrate trace elements in their soft tissues in higher levels than in water. Mussels are mollusks widely used as bioindicators of trace metal pollution in coastal areas because they can accumulate various elements as filter-feeders. In Brazil, Perna perna is one of the most commonly consumed bivalve mollusks and the most cultivated in coast regions. Therefore, the consumption of mussels may be a potential risk for human health, which enhances the importance to know trace metal levels in environment that provides food to humans. Due to constantly search for environmental quality and the use of mussels as food and often employed to monitor metal pollution in sea, it is of great interest and importance an overview of metallic contamination in national territory to assist in prevention of intoxication by trace elements.
