title: Mutagenicity of the halogenated olefin, 2-bromo-2-chloro-1,1-difluoroethylene, a presumed metabolite of the inhalation anesthetic halothane.
abstract: The presumed halothane metabolite, 2-bromo-1,1-difluoroethylene, produces both base substitution and frameshift mutations in Salmonella typhimurium. Direct mutagenesis of isolated DNA also was observed by using a Bacillus subtils transformation assay to score the production of mutagenic lesions in transforming DNA.
