Metal concentrations in Mytilus galloprovincialis from southern Dardanelles, Turkey

Author(s): A.Karafistan, H.B.Ormanci

Bioavailability of Pb, Cu, Cd, Ni, Zn and Al in the soft tissues of indicator mussels Mytilus galloprovincialis, sampled at the southern Dardanelles coastal area, has been investigated. Comparison of the results with the food codex values reveal threshold levels for lead, copper and cadmium, sometimes over passing the healthy consumption limits. From the multivariate statistical analysis of data it is found that metal content in these mussels are correlated (p<0.05) directly to the polluting source distances such as mining and other industrial discharges in the order of Pb>Cd>Cu.
