The purpose of this work is to analyse Cu, Zn, Pb and Cd simultaneously in biological samples such as serum, hair, tooth and bone using differential pulse stripping voltammetry (DPSV). Therefore, suitable sample preparation and experimental conditions are determined. Trace metal concentrations of biological samples are measured and compared with the literature values. Cu, Zn and Pb are found in hair, tooth and bone samples while Cu and Zn metals is found in serum sample.
