Abstract

In this study, the effect of depuration on heavy metals (Co, Al, Fe, Zn, Cu, Mn, Ni, Cd, Cr, Pb) in carpet shell collected from İzmir Bay, Turkey investigated. The depuration was carried out for the samples taken at the beginning and every 12 hours for a total of 72 hours. Inductive Coupled Plasma Optic Spectrometer (ICP-OES) was used to determined heavy metals levels in carpet shell. The levels of Co, Al, Fe, Zn, Cu, Mn, Ni, Cd, Cr and Pb in fresh carpet shell were measured as 1.23, 20.02, 87.29, 33.90, 11.39, 1.47, 2.90, 0.95, 0.36 and 0.92 mg/kg, respectively. In the heavy metal levels of carpet shell were showed fluctuation during the depuration. Levels of Al, Cu and Mn decreased, while Co, Fe, Zn, Ni, Cd, Cr and Pb increased in carpet shell at the end of the depuration. The results showed levels of Cd and Pb of carpet shell were found below the limits of Turkish Food Codex (R.G 29.12.2011-28157).
