[Evaluation of occupational exposure to cadmium on the basis of its concentration in the air and body fluids].

92 cadmium accumulators operators had their blood and urine cadmium concentrations determined. At nine workstations, during three years, repeated CdO concentrations measurements were made in the air by a stationary method, and additionally, at two workstations, measurements by an individual sampler were taken. The investigation showed a good correlation between CdO airborne concentrations measurements made by a stationary method and those made by individual samplers only at those workstations where workers do not change their place during a working day. Cadmiumuria indicated a greater dependence on the degree of exposure than did the concentration of this metal in blood. The findings suggest that cadmium concentration in blood and urine after body stores saturation is a better informant of current exposure than of cadmium stored in the organism.
