    Notes: Summary Sixty male workers in a lindane (y-hexachlorocyclohexane)-producing factory were examined with regard to health in comparison with an external control group of 20 clerks. Case history, physical examination, neurologic status, and ECG revealed no significant differences between groups. However, the following significant differences in clinical-chemical blood tests were ascertained: higher polymorphonuclear leukocyte count, lower lymphocyte count, higher reticulocyte count, lower prothrombin (Quick's) test, and lower blood concentrations of creatinine and uric acid. No significant differences were observed in total red and white blood cell as well as platelet counts, hemoglobin content, the other counts of differential blood picture, γ-GT, GOT, GPT, LDH, cholinesterase, triglycerides, cholesterol, and urea. In spite of a pronounced exposure to the α-, β-, and γ-isomers of hexachlorocyclohexane, no signs of severe impairment of health were observed; only small deviations in some laboratory tests were found having no pathologic significance. However, biological monitoring and health supervision of HCH-exposed workers should be carried out.

    Notes: Summary Sixty male workers in a lindane (γ-hexachlorocyclohexane) producing factory were examined with regard to functions of nervous system in comparison with two external control groups having no contact with hazardous substances. Examinations of reflexes and sensibility revealed no pathological signs. Mean values of amplitude and frequency of forefinger tremor were found at about 20 μm and 10 Hz respectively without significant differences between groups. Manual skill tested by means of a tracking task was nearly the same in HCH-workers and a control group of dairy workers. On the contrary, a control group of clerks showed significantly better results in the tracking test, a probable consequence of their occupational practice. In electromyography no pathologic patterns were observed. The maximal motor nerve conduction velocity of ulnar nerves showed nearly identical mean values of 59.5 m/s in HCH-workers and controls. Neuromuscular conduction as revealed by distal latencies was not impaired. Furthermore, electroencephalographic recordings taken in spot-checks of HCH-workers and controls did not show any specific pathological signs. Only small abnormalities in rhythm could be observed in some cases of workers as well as of control persons indicating no increased incidence in the HCH exposed group. In conclusion, even after years or decades of occupational HCH exposure, in this study no signs of neurological impairment or perturbation of “neuromuscular function” could be ascertained.
