The aim of the study was to determine the effects of chronic occupational exposure to white spirit on the efficiency of workers' intellectual and psychomotor functions. The exposed group consisted of 226 rubber industry workers while the control group comprised 102 hosiery plant workers. The analysis of results was aimed at the determination of exposure effects depending on the duration of exposure and age of persons examined. It has been revealed that chronic exposure to white spirit, at a concentration close to the hygienic standard, induces the deterioration of some intellectual and psychomotor functions in the exposed persons, depending on the duration of exposure and age of the exposed subjects. Among the variables presented in the study, several individual functions including: perception and reproduction of visual material; projection of spatial relationships; concentration; time of simple and choice reaction; speed and coordination of hand movements were found the most effective in contrasting the exposed group from the control.
本研究的目的是确定长期职业接触白酒精对工人智力和心理运动功能效率的影响。暴露组由226名橡胶行业工人组成，而对照组由102名针织厂工人组成。结果分析旨在根据接触时间和受检者年龄确定接触的影响。研究发现，长期接触浓度接近卫生标准的白酒精会导致接触者某些智力和心理运动功能的恶化，这取决于接触时间和接触对象的年龄。在该研究中呈现的变量中，发现包括视觉材料的感知和再现、空间关系的投射、注意力、简单反应和选择反应时间、手部动作的速度和协调性在内的几个个体功能，在区分暴露组和对照组方面最为有效。
