Mutagen and Oncogen Study of Methylhydrazine

Abstract : A three tier test was organized into a matrix of assays employing microbial cells, mammalian cells in culture, and in vivo experiments in rats and mice. Methylhydrazine (MH) was mutagenic for Salmonella typhimurium TA-1535 in suspension tests. Results from all other assays conducted as part of this evaluation were considered to be negative.
