J. Appl. Toxicol. 2(6) , 284-8, (1982)

The compound 2,3-epoxybutane (2,3-EB) is a direct mutagen for the base-pair-substitution-sensitive strains TA 1530, TA 1535 and TA 100, in the absence and in the presence of metabolic activation by li...

Assessing the potential for diol and hydroxy sulfate ester formation from the reaction of epoxides in tropospheric aerosols.

Environ. Sci. Technol. 43(5) , 1386-92, (2009)

Polyols and sulfate esters have recently been identified in the secondary organic aerosol (SOA) formed in the photooxidation of biogenic hydrocarbons both in the laboratory and under ambient atmospher...

Increase of 2,3-epoxybutane mutagenicity by glutathione-S-transferases.

Toxicol. Lett. 21(3) , 255-62, (1984)

The mutagenicity of 2,3- epoxybutane (2,3-EB) towards Salmonella FFphimurium TA1530 is increased by rat liver S9 mix. This enhancement can be induced by Aroclor 1254 (ARO) or phenobarbitone (PB) pretr...
