[Neural conduction in workers after long-term exposure to mercury vapors].

36 workers exposed to mercury vapour intoxication were examined to estimate the abnormalities in peripheral nervous system. 18 workers showed on physical examination features of polyneuropathy and in this group 15 workers had on emg examination sensory polyneuropathy. Statistical analysis was performed to show correlations between polyneuropathy on emg and age, time of exposure to mercury vapour and urinary mercury level. No such correlations were demonstrated.
