Thirty jet fuel exposed workers selected according to exposure criteria and thirty nonexposed controls from a jet motor factory were examined, with special reference to the nervous system, by occupational hygiene physicians, psychiatrists, psychologists, and neurophysiologists. The controls and the exposed subjects were matched with respect to age, employment duration, and education. Among the exposed subjects the mean exposure duration was 17 years, and 300 mg/m3 was calculated as a rough time-weighted average exposure level. The investigation revealed significant differences between the exposed and nonexposed groups for (a) incidence and prevalence of psychiatric symptoms, (b) psychological tests with the load on attention and sensorimotor speed and (c) electroencephalograms. When the control group was selected, it was ensured that the two groups were essentially equivalent except for exposure to jet fuel. It is concluded, therefore, that the differences found between the groups are probably related to exposure to jet fuel.
职业卫生医师、精神科医生、心理学家和神经生理学家对按照接触标准挑选出的30名接触喷气燃料的工人以及一家喷气发动机厂的30名未接触者进行了检查，特别关注了神经系统。对照组和接触组在年龄、工作年限和教育程度方面进行了匹配。在接触组中，平均接触时长为17年，粗略计算的时间加权平均接触水平为300毫克/立方米。调查显示，接触组和未接触组在以下方面存在显著差异：（a）精神症状的发病率和患病率；（b）注意力负荷和感觉运动速度方面的心理测试；（c）脑电图。在选择对照组时，确保两组除了接触喷气燃料外基本相当。因此得出结论，两组之间发现的差异可能与接触喷气燃料有关。
