✦ Synopsis

The determination of lead in blood, urine and bone (0.5 to 1.0 g blood, 5 to 10 ml urine, approx. 200 mg bone ash) by anodic stripping voltammetry is described. Blood samples are decomposed with nitric acid/perchloric acid, urine samples with nitric acid/perchloric acid/sulfuric acid. Bones are dry-ashed at 450 to 500 degrees C previously. The interference of iron in the analysis of blood samples is removed by adding citrate and adjusting the pH to approx. 3.5.
