Mutation induction in chinese hamster V79 cells by two vinyl chloride metabolites, chloroethylene oxide and 2‐chloroacetaldehyde

Abstract
Chloroethylene oxide and 2‐chloroacetaldehyde, two possibly carcinogenic metabolites of vinyl chloride in mammals, caused a dose‐dependent induction of 8‐azaguanine‐and ouabain‐resistant mutants in Chinese hamster V79 cells in vitro. Up to one‐hundredfold higher concentrations of 2‐chloroethanol or monochloroacetic acid, a urinary vinyl chloride metabolite in rats and man, were inactive.
