ASSOCIATIONS between lead (Pb) exposure and symptoms of anemia have been known for centuries. [1] Most modern investigators have ascribed the anemia of Pb poisoning to its well-known adverse effects on heme synthesis [2] or to other known effects of Pb, including shortened red cell survival, [3] ineffective erythropoiesis, [4] and inhibition of erythrocyte pyrimidine-5'-nucleotidase activity. [5] Grandjean et al. [6] recently described delayed blood regeneration capacity in Pb-exposed workers who had experienced normal hemoglobin (Hgb) concentrations and hematocrits prior to blood donation. That report led us to hypothesize that Pb may inhibit the production of ...
