[Neurobehavioral effects of chronic occupational exposure to mixtures of solvents used in furniture varnishing. Part II--Testing of visual evoked potentials].

The study involved a group of 40 workers chronically exposed to mixtures of organic solvents. The exposure did not exceed the allowed hygienic standard. Organic changes in the central and/or peripheral nervous system were not detected. Irregular visual evoked potentials were found in 9 (22.5%) of the exposed workers. The irregularities related primarily to the latency of some components of visual evoked potentials. Those changes occurred primarily within the group of workers employed for longer periods of time (16 years and longer).
