锰、铅、汞是我国常见的生产性毒物,易引起职业危害。1979年,我们依据全国职业病普查的统一方法,对北京地区40个铁路厂,段、站接触铅,苯,汞、锰的工人共1050名进行了健康检查,对其中出现种衰症侯群或植物神经功能紊乱以及疑似锥体外系受损者作了脑电图和肌电图的检查,试图用电生理学方法提供神经系统早期病损的客观证据,以进一步评价毒物危害的程度。兹将结果报导如下: 对象和方法脑电和肌电图受试者共37(男30,女7)名,年龄平均为40(21～59)岁,接触工龄平均为16(1～36)年,其中锰、铅、汞接触者分别为29、5和3名。脑电图检查:应用丹麦Kaisers TR-60型8 Manganese, lead, mercury is a common production poison in our country, easy to cause occupational hazards. In 1979, according to the unified method of the National Occupational Disease Census, we conducted a health check on 1050 workers exposed to lead, benzene, mercury and manganese in 40 railroad factories, stations and stations in Beijing, Autonomic dysfunction and suspected extrapyramidal lesions were examined by EEG and EMG in an attempt to provide objective evidence of early neurological damage using electrophysiological methods to further assess the extent of the toxic hazard. The results are reported as follows: Subjects and Methods Electroencephalography and electromyography subjects a total of 37 (male 30, female 7) name, the average age of 40 (21 to 59) years of age, average length of exposure to work for 16 (1 to 36) Year, of which manganese, lead and mercury contact were 29,5 and 3 respectively. EEG examination: application of Danish Kaisers TR-60 type 8
