Determination of some trace elements in chicken eggs from different sources

Abstract

For most people, diet is the main way of exposure of heavy metals and trace elements and consequently the risk assessment of these elements to humans through dietary intake is important. The purpose of this study was to evaluate the levels of Mn, Co, Cu, Se and As in egg of chicken and quail from different location. Trace elements were determined by inductively coupled plasma-mass spectrometry (ICP-MS).The result found that disparity in metals concentrations in eggs among avian species, the eggs of chicken were gathered high concentration of iron compare with lowest concentration of cobalt. Additionally, the eggs that collected from village have low concentrations of these trace elements while the high levels of trace element reported in the eggs that collected from commercial farms.
