Hair was found to be the excretory tissue for essential, non-essential and toxic elements. Toxic levels provide a better indication of body stores than is evident from the levels in blood or unprovoked urine speciments. Human hair levels of toxic elements including cadmium, lead and copper have been highly correlated with modem pathological disorders. However, nutrients such as iron can also become toxic when it present at high level. In the present study the effect of using different ratio for different solvents as well as different digestion time for digestion of hair and nails were investigated. The established methods of digestion for both types of samples (hair and nails) were applied for determination of cadmium, copper, iron, lead and zinc in a collected samples. The results obtained for the analysis of hair samples showed an increase in the concentration level of zinc comparing with other elements, while for the analysis of nails, iron showed the highest level of concentration between all determined elements. |
