✦ Synopsis

The analysis of human hair is useful in monitoring the levels of certain trace elements in the body. Hair samples can be collected easily and painlessly, and they require no special care when stored. Unlike blood, hair gives information about the intracellular accumulations of trace elements and provides information about a longer period. We have considered the references, developed an analytical method, and optimized the measuring conditions. The risk of sample contamination during the sampling and digestion was minimized. Different washing procedures and digestion methods were studied. Prior to analysis, hair samples were washed with organic solvent, nonionic detergent, and double-distilled water. Hair samples were prepared by using atmospheric digestion followed by microwave digestion. The concentrations of Ba, Ca, Cu, Fe, Mg, Mn, Pb, and Zn were determined by inductively coupled plasma atomic emission spectrometry.
