Resumo
This short note aims to report in detail a preliminary assessment of the concentrations of Cd, Hg and Pb in tissues of blue
crabs Callinectes danae collected from the Cananéia-Iguape-Peruíbe estuarine complex (CIP), in the South of São Paulo
State coast, Brazil. In October 2014, blue crabs were collected from CIP. Tissues were removed by dissection and metal
determination was performed by GF-AAS and CV-AAS. According to statistical analysis, Pb and Cd concentrations in gills
were significantly higher than those found in muscles and hepatopancreas, respectively. There were no significant differences
in Hg concentrations between samples. Cd, Hg and Pb concentrations in gills and hepatopancreas were lower than those
reported in a previous study performed at CIP. However, Cd concentration in hepatopancreas was higher than the Brazilian
limit for consumption and new efforts to monitor Cd concentrations in C. danae tissues must be performed.
