DETERMINATION OF HEAVY AND TRACE METAL LEVELS IN MYTILUS GALLOPROVINCIALIS AND THE EFFECT OF MICROWAVE COOKING

摘要

Determination of cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni) and lead (Pb), and the effects of cooking on these metal levels were determined by atomic absorption spectropho-tometer in mussel samples (Mytillus galloprovincialis, n:30). The samples were collected from Eminoenue, Istanbul. The concentrations of heavy metals were expressed as mg kg~(-1) wet weight of tissue. The results of cooked and un-cooked mussel samples were statistically compared. With regard to the un-cooked samples, decrease in Cu, Co, and Ni concentrations was very significant (P<0.01), whereas that of Cd, Mn, and Cr was not significant (P>0.05). The decrease of Pb and Fe values was also significant (P<0.05).
