Description of key information
Additional information
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.
