Abstract
Various neurophysiological methods, including electroencephalography, electromyography, nerve conduction velocities, and evoked potential techniques, have been used to detect early signs of neurotoxicity in humans. These methods have been applied to groups of occupationally exposed workers and their referents in epidemiologic studies, to patients with suspected or proven diseases after long-term work in toxic environment, and to human subjects during or after experimental exposure. The main body of knowledge arises from epidemiologic studies of occupationally exposed subjects, and several chemicals widely used in industry have been shown to be neurotoxic. Of these, e.g., lead causing peripheral neuropathy, some solvents like carbon disulfide, n-hexane, and methyl n-butyl ketone also causing neuropathy and at times central nervous system effects as well as acryl amide have been studied using neurophysiological approaches. Several other solvents including toluene, xylene, and various mixtures of organic solvents have been suspected to be neurotoxic, and nervous system effects have been ascribed to those in several neurophysiological studies. Some studies have elucidated acute nervous system effects of ethyl alcohol or industrial solvents in experimental situations applying, for example, evoked potential techniques or electroencephalography.Keywords
