Nineteen caisson workers had been exposed to metallic mercury vapours while digging tubes underneath the first district of Vienna (exposure between 470 and 2440 min; mean 1621 min). The blood mercury values on admission were between 29 and 166 micrograms/l (mean 75 +/- 34 micrograms/l). The main findings reported are clinical neurologic symptoms, psychic complaints, neurographic results and autonomic parameters (cardiovascular reflexes): 47% complained of headache and tiredness, 37% showed tremor and suffered from sleep disturbances, 26% showed hypersalivation, 16% changes in handwriting, and 11% slight dysarthria. The cardiovascular reflexes (autonomic parameters) were abnormal in 7 of 12 patients. On neurography the distal latency (median nerve) was pathologic in 47%, the distal latency (peroneal nerve) was pathologic in 26%, the antidromic sensory nerve conduction velocity (median nerve) was abnormal in 10%, the motor nerve conduction velocity, compound amplitude and vibratory threshold were normal.
19名沉箱工人在维也纳第一区下方挖掘管道时接触到金属汞蒸气（接触时间在470至2440分钟之间；平均1621分钟）。入院时血汞值在29至166微克/升之间（平均75±34微克/升）。报告的主要发现包括临床神经症状、精神主诉、神经电图结果和自主神经参数（心血管反射）：47%的人抱怨头痛和疲劳，37%的人出现震颤并患有睡眠障碍，26%的人出现流涎过多，16%的人笔迹改变，11%的人有轻微构音障碍。12名患者中有7名的心血管反射（自主神经参数）异常。在神经电图检查中，47%的患者正中神经远端潜伏期病理改变，26%的患者腓总神经远端潜伏期病理改变，10%的患者正中神经逆向感觉神经传导速度异常，运动神经传导速度、复合波幅和振动阈值正常。
