While the health of the general population is not adversely affected by the 
exposure the pesticides in food and environment, workers, who have during their 
occupation been intensely exposed to pesticides, exhibit a higher prevalence of 
slight neurotoxic symptoms. In the present study the electroencephalograms of 3 
of a group 10 workmen, who had been continually exposed to hexachlorcyclohexane, 
show pathological findings. The electromyograms of 8 of these 10 workman 
demonstrate a disturbance of the peripherical motoneuron. All probands, who 
exhibit o pathological EEG, also show a polyneuropathy.
