Reaction Products of C3 alcohols and C3 alkenes was found to be not
readily biodegradable in an OECD 301 headspace test, although it should
be recognized that standard biodegradation methods are of limited value
for volatile and complex streams. A review of the biodegradability of
the major constituents of the stream suggests that isopropyl ether is
the most persistent component. It has been shown to be not readily
biodegradable in a closed bottle test with unadapted inocula (Stone and
Watkinson, 1983) and QSAR prediction (BIOWIN v4.1). More recent studies
(Cano et al, 1999 and Pruden et al, 2001), have shown that high removals
rates of DIPE can be demonstrated if exposed to acclimated inocula;
however for the purpose of hazard/persistence/ risk assessment, DIPE,
cannot be considered to be readily biodegradable. Given the potential
persistence of DIPE and the result of the OECD 301 screening study for
the whole stream, Reaction Products of C3 alcohols and C3 alkenes,
cannot be considered to be readily biodegradable.
