The present study aims to determine the concentrations of the selected heavy metals in different food categories.

Material and methods:
The digested solution from fifty-seven food samples 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.

The ICP-AES and AAS techniques were used to identify the contents of Pb, Ni, Cd, Cu and As in diet samples. The working calibration from ICP-AES and AAS measurements shows a very good linear relationship with low values of LoD and LoQ. The two analysis methods gave relatively close results with a preference to the ICP-AES technique. Some Seri lank and Chinese rice samples had more Arsenic concentration than that allowed according to the international requirements. Therefore, strict inspection should be carried out on these rice brined.
