(cest2017_00569) Assessment of Heavy Metals in Wild Mussels Mytilus Galloprovincialis From the Marmara Sea Coast of Tekirdag (Turkey)

摘要

Concentrations of eight heavy metals (Cd, Cr, Cu, Hg, Ni,As, Pb, and Zn) were identified in tissues of the musselMytilus galloprovincialis that are seasonally collectedalong the Marmara coast of Tekirdag. The concentrations(mg/kg d.w.) of these metals ranged from 1.20 to 2.79 forarsenic (As), 0.13 to 0.75for cadmium (Cd), 0.42 to 2.46for chromium (Cr), 1.55 to 3.5 for copper (Cu), 1.01 to2.46 for nickel (Ni), 76.8 to 88.98 for zinc (Zn), and 2.67to 9.2 for lead (Pb). These levels were lower than thepermissible limits set by the European Commission andFood and Drug Organisation Permissible limits for Pb, As,and Zn were exceeded during some periods. Evaluation ofthe public health risk associated with consumption ofmollusks indicates that there is no evidence of risk to theMytilus Galloprovincialis consumer. However, becausechronic exposure of to trace metals can cause healthproblems for humans, toxic chemicals must be periodicallyand carefully monitored.
