[Effectiveness of preliminary medical examinations in evaluating the status of the nervous system in persons to be exposed to organic solvents].

Evaluation of pre-employment examination qualifying to working in exposure to organic solvents is presented. Neurological examination was performed on 161 men employed for about 3.6 year in the plant of vinyl chloride and organic solvents synthesis. The nervous system evaluation as well as the ability to work in exposure to neurotoxic substances is discussed. Numerous changes in the nervous system were found which must have existed already on beginning working. The analysis performed proved that pre-employment examination is too general and, without the participation of a neurologist, not effective enough to stop employing people suffering from the nervous system diseases in exposure to neurotoxic substances.
