A preliminary assessment of metal bioaccumulation in the blue crab, Callinectes danae S., from the Sao Vicente Channel, Sao Paulo State, Brazil.

The concentrations of metals in tissues of Callinectes danae were evaluated, aiming to determine the bioaccumulation process of this species. Gills presented the highest mean concentrations for most metals, except for Hg (<LOD) and Zn (13.293 μg g(-1)). According to results of the principal component analysis, the type of tissue was distinguished due to the concentrations of metals. An evaluation of individuals from other sites of the Santos Estuarine System (where the Sao Vicente Channel is included) would be important to confirm if this pattern of bioaccumulation can be extended to the population of C. danae of this estuary.
