In this investigation the environment of vanadium workers was studied. It was found that low concentrations of vanadium (0.01--0.04 mg/m3) in the air do not correlate with vanadium serum levels or its urinary excretion. The results, however, suggest that values of vanadium in serum and urine samples reflect absorption of vanadium because vanadium could not be detected in the urine of referents. In higher vanadium exposure (0.2--0.5 mg/m3), the concentration in the air inhaled remaining unknown due to the use of dust masks, urinary vanadium excretion and serum vanadium level decreased significantly with exposure-free time.
在本次调查中，对钒作业工人的工作环境进行了研究。结果发现，空气中低浓度的钒（0.01--0.04毫克/立方米）与血清钒水平或尿钒排泄量并无关联。然而，研究结果表明，血清和尿液样本中的钒含量反映了钒的吸收情况，因为在对照者的尿液中未检测到钒。在较高的钒暴露水平（0.2--0.5毫克/立方米）下，由于使用了防尘口罩，吸入空气中的钒浓度未知，尿钒排泄量和血清钒水平随脱离暴露时间显著下降。
