Determination of potentially toxic elements and health risk assessment of dried fruits.

This study aims to measure the concentrations of As, Cd, Pb, Cr, and Ni in dried fruits and examine the health effects of these trace metals in relation to people's daily dietary intake. 29 samples of dried fruits purchased at bazaar place were analyzed in terms of toxic elements, which have been reported as cancerous by the World Health Organization (WHO). Dried fruits were digested in a microwave oven with HNO(3) and H(2)O(2). Metal concentrations (As, Cd, Cr, Ni, and Pb) in these samples were measured using inductively coupled plasma mass spectrometry (ICP-MS). Linearity, limit of detection (LOD), limit of quantification (LOQ), specificity/selectivity, and recovery (%) were all evaluated. The correlation coefficients of elements in this method were good (R(2) > 0.9997). The amount of consumption in the area was used to calculate a health risk assessment. The results showed that the samples of dried fruit, which are widely consumed in the identified area, had variable levels. All dried fruits had element concentrations that were lower than the WHO/FAO safe limit.
