Four structurally related aliphatic epoxides (1,2-epoxypropane, 1,2-epoxyisobutane, cis- and trans-2,3-epoxybutane) have been tested in the Salmonella/microsome assay, modified for volatile substances, using the strains TA1535 and TA100. The aim of the study was to evaluate the effect of methylation on
