[Comparative assessment of the clastogenic potential of various industrial enterprises]

The paper comparatively assesses the level and qualitative spectrum of chromosomal aberrations (CA) in 192 workers engaged in 3 industries (cake and by-product, aluminum, and mining concentration processes). The maximum and minimum rates (6.43(+)-0.32% and 3.81(+)-0.46%) of CA have been observed in those engaged in cake and by-product and mining concentration processes, respectively. The combined influence of chemical and radiation factors are a cause of the higher rate of CA. Gender- and age-specific features do not effect on the level of structural CA. Smoking is a factor of their slight modification as there are no significant differences in the frequencies of aberrations between smokers and non-smokers in any professional group. There is an indirect relationship between the frequency of CA and the length of service, which may be different under the conditions of various industries.
