Trace element levels in some dried fruit samples from Turkey

Abstract

Trace element levels in nine different dried fruit samples from Kayseri, Turkey were determined by flame atomic absorption spectrometry after dry and wet digestion methods. Good accuracy was assured by the analysis of standard reference material (NIST-SRM 1515-Apple Leaves). The contents of trace elements in the samples were determined in the ranges of 1.68–4.52, 0.6–9.4, 5.5–12.4, 6.76–64.1, 4.74–25.5, 0.2–1.78, 0.8–6.17 and 0.1–0.81 µg/g for copper, nickel, lead, iron, manganese, cobalt, chromium and cadmium, respectively. The highest copper content was 4.52 µg/g in black grape, highest nickel content was 9.4 µg/g in black plum, highest lead content was 12.4 µg/g in apricot, highest iron content was 64.1 µg/g in apricot, highest manganese content was 25.5 µg/g in rose hip, highest cobalt content was 1.81 µg/g in white mulberry, highest chromium content was 6.17 µg/g in yellow plum and highest cadmium content was 0.8 µg/g in apricot and rose hip. The results were compared with the literature values.
