The lead content of hair from the electric razor can be determined by atomic absorption spectrometry, using the micro-sampling technique of Delves. 1--5 mg of the washed and dried hair are partially oxidized with hydrogen peroxide prior to analysis. The method is simple and quick and therefore suited for the serial investigation of persons exposed to lead.
