[Electronystagmographic examinations in workers exposed to metallic mercury vapors].
In order to evaluate the vestibular organ electronystagmography was performed in 20 workers employed in the mercury cathode method of potassium chloride electrolysis, and exposed to metallic mercury vapours at air concentrations 0.035-0.05 mg/m3. In 15 (75%) workers a central impairment of the vestibular organ was shown, whereas in 50 healthy controls an abnormal electronystagmogram was found only in 9 (18%) people. Electronystagmography seems to be a useful tool in the assessment of early signs of the central nervous system dysfunction caused by metallic mercury.
