The relationship of blood lead level (BLL) and blood cadmium level (BCL) with hematological and oxidative stress parameters was evaluated in exposed workers (50 painters and 23 battery workers) and control subjects (36). The changes in oxidative stress and hematological parameters were distinctively associated with either BLL or BCL. Thioredoxin reductase activity was not changed in the exposed workers. However, biochemical and hematological changes at low BLLs underlie the necessity of reevaluating the recommended health-based limits in occupational exposure to this metal.
