Several biodegradation studies are reported for 1,3,5
trioxane. Based on the results of these studies, it can be concluded
that trioxane is inherently biodegradable. Trioxane was found not to be
biodegradable in 28 days using a MITI test. Volatilization was found to
be a significant mechanism of loss under aeration conditions. A standard
Zahn-Wellens (OECD 302B) inherent biodegradation test suggested
biodegradation was occurring but the relative contribution of
volatilization was not determined. A modified Zahn-Wellens test was
conducted using a closed system with sodium nitrate as the oxygen
source. In this study, more than 90% of the DOC was removed in 18 days
while only minimal loss of DOC was observed in controls without
bacterial inoculum. This indicates that Trioxane is effectively removed
via biodegradation from wastewater at a treatment plant.
