Subjective symptoms and psychological performances on a computer-administered test battery were studied among a group of 60 chlorine-alkali workers and their matched referents. The exposure time of the group exposed to inorganic mercury vapor had been about 14 years, and the estimated long-term average exposure had been about 25 micrograms/m3 of air. The exposed workers had an actual mercury concentration of 51.9 (SD 25.0, range 15-150) nmol/l in blood and 84.1 (SD 56.6, range 15-260) nmol/l in urine. Neither perceptual motor nor memory nor learning abilities of the mercury-exposed workers showed any disturbances in a comparison with the referents. However, the exposed group reported statistically significantly more memory disturbances than the referents. Strain caused by three-shift work was a possible cofactor for other increased subjective symptoms, namely, for sleep disorders, fatigue, and confusion.
在一组60名氯碱工人及其匹配的对照对象中，研究了在计算机管理的测试组合上的主观症状和心理表现。暴露于无机汞蒸气的组的暴露时间约为14年，估计长期平均暴露量约为25微克/立方米空气。暴露工人的血液中汞实际浓度为51.9（标准差25.0，范围15 - 150）纳摩尔/升，尿液中为84.1（标准差56.6，范围15 - 260）纳摩尔/升。与对照对象相比，汞暴露工人的感知运动、记忆和学习能力均未显示出任何干扰。然而，暴露组报告的记忆障碍在统计学上显著多于对照对象。三班制工作引起的压力可能是其他主观症状增加的一个辅助因素，即睡眠障碍、疲劳和困惑。
