  • Title: [Evaluation of mental functions in workers exposed to metallic mercury, inorganic lead and carbon disulfide].
    Author: Sikora A, Langauer-Lewowicka H.
    Journal: Med Pr; 1992; 43(2):109-21. PubMed ID: 1435245.
    Abstract:
    The aim of the study was to determine the similarities and differences between the groups of dysfunctions detectable using psychologic tests in workers exposed to metallic mercury, inorganic lead and carbon disulfide. The study groups included male workers examined in the Clinic of Occupational Diseases of the Institute of Occupational Medicine in Lodz. The subjects were supposed to the chronically intoxicated with Hg (27 persons), Pb (40 persons) and CS2 (40 persons). A wide variety of tests was used to examine reference groups matched appropriately according to sex, age and level of education. The comparative analysis of results showed that the range and extend of a decrease in psychic functions depend on the type of a neurotoxic agent. The most serious disorders (frequently those of organic brain disease type) were found in subjects exposed to CS2. Exposure to metallic mercury resulted in functional disorders of the psychic sphere, while exposure to inorganic lead caused some minor functional changes. The results of the psychological examination of the subjects may be useful both for individual analysis and for screening.
