The Determination of Some Heavy Metals in Different Selected Diets

Abstract

The present study aims to determine the concentrations of the selected heavy
metals in different food categories. Fifty-seven food samples were collected and digested
using a mixture of analytical grade of strong mineral acids. The digested solution analyzed
by ICP-AES and AAS techniques to determine quantitatively the concentration of lead,
Arsenic, cadmium, copper and nickel in the investigated samples. The levels of the
interested metals were compared with the maximum acceptable levels of heavy metals
contents in food items according to the Codex alimentarius and the European Commission
regulations in order to evaluate the potential risks and contamination. The study inducted
that most of heavy metals in food samples were within acceptable levels except some rice
samples had more arsenic concentration than the acceptable levels
