title: Additional data on the mutagenic effect of dinitro-o-cresol-containing herbicides.
abstract: In in vivo experiments in mice it was studied, on the one hand, whether 1 year after treatment with dinitro-o-cresol (DNOC)-containing herbicide it was possible to detect any increase in chromosome aberrations in the bone marrow cells of the mouse, and on the other hand, to learn the frequency of chromosome aberrations in the subsequent generations when the treatment of the male animals with DNOC-containing herbicide was continued in each generation and when it was discontinued before mating. The chromosome aberrations of the bone marrow cells of the treated mice were demonstrated even 1 year after the treatment. After the treatment of the male animals was continued in each subsequent generation, the chromosome aberrations in the embryos increased, whereas when it was discontinued, it decreased in the subsequent generations.
