[Psychomotor efficiency of persons chronically exposed to carbon disulfide. II].

The study is aimed at the determination of CS2 effects upon selected indices of psychomotor efficiency, depending on the level of exposure to carbon disulphide and duration of employment. The study involved 250 viscose industry workers exposed to CS2 and 126 persons not exposed to toxic substances at work. The following tests and appliances were used: Eye-hand coordination test, Turner test for independent movement of two hands, reaction time meter, one-plate tapping, two-plate tapping and modified d'Heuyer and Baille's tests. A strict connection was found between the results obtained and length of employment in CS2 exposure. Most results were getting aggravated with time of employment. On the other hand, no significant differences in the level of indices in groups classified by different levels of exposure were found, though in many tasks a tendency towards results deterioration, with time of exposure, was found. The lack of significant differences was accounted for by the inability of evaluating the CS2 exposure throughout the whole occupational exposure period.
