[Evaluation of the nervous system in workers in the furnace and coal divisions of the coke-producing plants].

240 workers of coking plant exposed to noxious chemical compounds released at coke production and control group consisting of 76 persons including 48 workers without direct contact with coke production process and 28 randomly selected healthy subjects were examined. No characteristic syndrome of subjective changes was found in workers of productive sphere. However, defective neurological symptoms were more prevalent in this group as compared to the controls. The workers from the group exposed developed neurotic syndromes with vegetative disregulation symptoms two times more frequently than the controls. The changes in EEG were significantly more prevalent in the workers occupationally exposed. The prevalence of diffuse changes in EEG depended on the level of exposure to BaP.
