Special physical examinations were made in order to find out the actual status of damages to health that had broken out in a factory collecting V_2O_5 from iron sand; and the following results were found: 1. Pharyngitis and bronchitis were found in 25% of the workers exposed to vanadium, but neither pneumonia nor hepatitis was observed. 2. Among the subjective and objective symptoms, respiratory irritation and discoloration of the tongue were frequent. 3. Black spot-like pigmentations gathering in a zonal form 1-2mm wide in the transitional part and oral mucosa of the upper lip were found. Prevalence rate of this sign was 14.3% in the workers exposed to vanadium. 4. The mean valus of total serum protein and the serum cholesterol in the exposed workers were lower than those in the controls. The difference in the values between both groups is statistically significant. 5. Both the mean values of vanadium concentrations in urine and its creatinine ratios in the exposed workers were twice to three times those in the controls; however, these parameters decreased to about one third in two months by improving the health and environmental controlmeasures. 6. Draft items to be checked in special physical examinations of workers handling vanadium have been proposed.
