Impairment of nervous system in workers exposed to inorganic mercury.
Impairment of nervous functions has been investigated by clinical and neurophysiological methods in 55 workers exposed to inorganic mercury intoxication and 27 controls living in the same area. A polyneuropathy, mainly of sensory type, has been found in 6 exposed workers (10,9%) and 2 control (7,4%); a mono or multineuropathy of sensory or motor type was present in 15 exposed (27%) and 10 control (29,6%) subjects. Central N.S. involvement has been found in 7 out of 12 exposed workers examined and in 1 out of 7 controls by electronystagmography. Neurological examination demonstrated minor signs of cerebellar type in 3 instances.
