Abstract
The aim of this study was used to investigate the level of trace metals (Ba, Pb, Cd, Mn, Cr, Co, Ni, Cu, Mn, Zn, Sr and Fe) in some dried fruits (Prunus domestica L., Ficus carica L., Morus alba L., Vitis vinifera L., Prunus armeniaca L., and Malus domestica) samples from Turkey. Trace elements were determined by ICP-OES after dry, wet and microwave digestion methods in dried fruit samples. Validation of the proposed method was carried out by using a NIST-SRM 1515-Apple Leaves certified reference material. Element concentrations in dried fruit samples were 0.33-1.77 (Ba), 0.12-0.54 (Cd), 0.25-1.03 (Co), 0.45-2.30 (Cr), 0.43-2.74 (Cu), 0.56-4.87 (Mn), 0.61-2.54 (Ni), 0.40-2.14 (Pb), 2.16-6.54 (Zn), 0.83-12.02 (Al), 11.82-40.80 (Fe) and 0.16-6.34 (Sr) μg/g. The analytical parameters show that the microwave oven digestion procedure provided best results as compared to the wet and dry digestion procedures. The results were compared with the literature values.
