Mutagenicity of polycyclic hydrocarbons. II. Monitoring genetical hazards of chrysene in vitro and vivo.

Mutagenicity tests were performed with chrysene in the Salmonella/microsome test, NMRI-mice oocytes, bone-marrow cells and spermatogonia of Chinese hamsters. Only in mice oocytes was a weak but significant increase of structural chromosome aberrations observed. Correlations were found between weak carcinogenic and observed weak mutagenic activities of chrysene in vitro and in vivo.
