Concentrations of toxic metals can he determined in a drop of blood, such as might be obtained from a finger-prick, by spotting the blood onto filter paper, drying it, and then burning a standard size disc punched from the filter paper in an atomic absorption spectrophotometer. Results for lead, cadmium and zinc determined in this manner compare favorably with accepted macro-methods of analysis. The advantages of this procedure, namely the ease of specimen collection and the simplicity of the analysis, may make this the method of choice in biochemical monitoring for trace metal absorption by workers.
