[Determination of cadmium concentration in the air of a battery manufacturing plant by the method of alternating current polarography].

Concentrations of cadmium at 9 selected workplaces were measured for 3 years. Cadmium was determined by squarewave polarography. Results ranged between 0.024 mg/m3--0.737 mg/m3 (mean concentrations). The highest concentrations occurred at cadmium electrodes production for strip plate batteries. The study of cadmium concentration along with medical examinations allowed to specify how far Vitamin C administration might affect the health status of cadmium--exposed workers.
