C12-14 AO is readily biodegradable in a
number of studies performed to OECD TG 301 B or D. In a continuous
activated sludge (CAS) test removal of parent amine oxide was > 99.8 %
in both units. In a monitoring study, the influent and effluent
concentrations of C12 and C14 amine oxide was measured in six municipal
sewage treatment plants. The BOD removal was 96-98 %. On the basis of
these studies, a removal rate in STP of 98 % is proposed for modelling.
In a river water die away study the half-life of amine oxide was
determined to be 3.2 days. In a biodegradation test performed using
anaerobic digester sludge the rate constant for mineralization of the
amine oxide was 1.32/day.
Based on these studies, performed under both
aerobic and anaerobic conditions, it is expected that amine oxides will
be rapidly degraded in the environment, both in the aquatic environment
and in soil and sediment.
