Due to the mathematical method of maximum probability it was established that under long-term chromium exposure possible factors of risk of changes in the workers' nervous system were as follows: hereditary and familial predisposition to allergic and vegetovascular disorders, negative Rh, the haptoglobin type 2-2 and the peculiarities of the major cerebral hemisphere functioning manifested by the decrease of sensomotor dominance.
