although the initial time-course was different between butadiene monoxide and ethylene oxide ( with a high initial increase of ethylene oxide and a subsequent decrease ) an analysis at steady-state ( plateau concentrations ) revealed that only 29 % of the amounts of both epoxides which in theory are formed as primary metabolites from the parent olefins are systematically available ( i.e. , distributed in the entire organism ) .
