In a fluorescent lamp production factory, a newly developed lightweight balance-tremormeter was used to measure postural tremor of the finger in 21 workers (ages 28 to 61) exposed for 0.5-19 yr to metallic mercury. In addition, tremor was measured in an indirect way by means of a "hole-tremormeter." The excretion of mercury in urine was 9-53 (average 20) mumol/mol creatinine. With increasing mercury excretion, the following parameters increased: the acceleration of the tremor, the contribution of the neuromuscular component (8-12 Hz) to the power spectrum of the acceleration, the width of the power-spectrum and the score on the hole-tremormeter. The study indicates that exposure to metallic mercury below the current TLV (50 micrograms/m3) may increase the tremor of the finger.
在一家荧光灯生产厂，使用一种新研发的轻型平衡震颤仪对21名（年龄在28至61岁之间）接触金属汞0.5至19年的工人的手指姿势性震颤进行了测量。此外，还通过“孔洞震颤仪”以间接方式测量了震颤。尿汞排泄量为9至53（平均20）微摩尔/摩尔肌酐。随着汞排泄量的增加，以下参数也增加：震颤加速度、神经肌肉成分（8至12赫兹）对加速度功率谱的贡献、功率谱宽度以及孔洞震颤仪得分。该研究表明，接触低于当前阈限值（50微克/立方米）的金属汞可能会增加手指震颤。
