Mineral and heavy metal levels of some fruits grown at the roadsides.

The rate of heavy metal pollution of some minor fruit samples growing at the roadsides in Turkey were determined by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). Pb, Zn and Cu were found at the high levels in the fruit samples. The results showed that the average level of Cu changed between 0.27 mg/kg (Sample 11) and 0.05 mg/kg (Sample 15), Cr 0.32 mg/kg (Sample 14) and 0.18 mg/kg (Sample 13), Ni 0.68 mg/kg (Sample 12) and 0.26 g/kg (Sample 15), Pb 2.86 mg/kg (Sample 12) and 1.54 mg/kg (Sample 4) and Se 12.96 mg/kg (Sample 14) and 5.42 mg/kg (Sample 7). The levels of Cu, Cd and Cr in samples do not appear to reach pollution levels. Copyright 2010 Elsevier Ltd. All rights reserved.
