| Abstract: | The concentration assessment of Hg, Pb, Cd, Cu, Zn, Cr, Mnand Fe in marine mussels Perna perna, sampled at 15stations along the 800 km Southern Brazilian Coast, has beencarried out. Samplings were taken twice, in summer andwinter of 2000. The concentrations found were lower thansimilar studies carried out along the Central Coast of Brazil andlower than the maximum limits permitted in bivalve molluscsdesignated for human consumption (Brazilian, Spanish andLuxembourg legislation sets). The data also showed lowervalues compared with other regions of the world. Thecomparison of present data with the data obtained 10 years agoat the same stations did not show significant differences,consequently the concentrations found could be used asbaseline values. |
