RESUMO

Cernik, A. A. (1974).British Journal of Industrial Medicine,31, 239-244. Determination of blood lead using a 4·0 mm paper punched disc carbon sampling cup technique. The method described is designed to overcome difficulties associated with presentation of the sample and its analysis for lead in blood. Chromium-51 studies on the effect of spread showed that imprecision resulted when discs of less than 4·0 mm diameter were punched from a given blood spot. The best standard deviation and relative standard deviation for increasing lead concentrations was obtained when 4·0 mm discs were used.
