Sixty welders (20 each from Plants A, B, and C) and 20 control subjects were investigated for the possible occurrence of manganese poisoning among welders exposed to the welding fumes containing this metal. Ten, 9, and 5 welders from Plants B, C, and A, respectively, were diagnosed as suspected cases of early manganese poisoning. The diagnosis was based on the proof of overexposure to manganese by the findings of increased urinary levels of this metal, signs of early neurological involvement, and increased contents of serum calcium. These results are discussed in relation to the manganese concentration in the air around the welder's breathing zones.
对60名焊工（A、B、C厂各20名）和20名对照对象进行了调查，以研究接触含锰焊接烟雾的焊工中可能发生的锰中毒情况。B厂、C厂和A厂分别有10名、9名和5名焊工被诊断为早期锰中毒疑似病例。诊断依据是通过尿中该金属水平升高、早期神经受累迹象以及血清钙含量增加的结果证明锰暴露过量。结合焊工呼吸区周围空气中的锰浓度对这些结果进行了讨论。
