Additional information

The biodegradability of 1.2-epoxybutane was investigated in several studies. 1.2-epoxybutane is readily biodegradable in a headspace test according to ISO guideline 14593. After 28 days 80 - 90 % carbon dioxide evolution was measured [BASF AG, 2000]. Additionally the substance was readily biodegradable in a DOC-Die-Away test, but missing the 10 day window [DOW, 1999].
