[Chromosome aberrations in the somatic cells of mammals evoked by chromium compounds].

It is established that potassium bichromate (K2Cr2O7) in chronic and acute poisoning evokes a significant increase in frequency of cells with chromosome aberrations in bone marrow of rats. Mutagenic effect of chromium compounds is not always in correlation with their toxic action. It is supposed that chromium compounds possess the properties of chemical mutagenes of delayed action.
