[Assessment of early psychic dysfunctions due to metallic mercury]

The aim of the study was to find the most sensitive psychological test battery, useful for evaluation of the earliest dysfunctions in workers exposed to metallic mercury (Hg). To assess the above mentioned disorders, six tests of interference and four tests of motor reactions were applied. The examinations were performed in 44 male workers exposed to Hg in the process of acetic aldehyde synthesis. The control group was matched for sex, age and educational level. The obtained results showed that in the detection od early dysfunctions of the nervous system, psychological tests of interference are more useful than test of the motor reactions. This toxicological test battery can be recommended for monitoring workers exposed to metallic mercury.
