Biodegradation in water: screening test
No data with the test substance are available. A weight of evidence approach with the read across substance melamine (CAS 108-78-1) is applied. Based on the reported studies, which are consistent in the result: melamine is not inherently biodegradable and also not readily biodegradable (% degradation (DOC removal) < 10 % in 28 days according to OECD 302 B (1992) in the study (Taeger, 1993 (BASF SE)). Based on this result, the target substance is considered to be not readily biodegradable. Biodegradation, also stepwise, t cyanuric acid and lastly to CO2 and NH4+ can occur in waste water treatment plants with adapted microorganisms.
Biodegradation in water and sediment: simulation test
A biodegradation in water and sediment simulation test does need not to be conducted. A log kow of -3 (at 25 °C) and a determined log Koc < 1.3 indicate low potential for adsorption to solid soil/sediment . Thus, a simulation test on biodegradation in water and sediment does not need to be conducted.
Biodegradation in soil
A biodegradation in soil does need not to be conducted. A log kow of -3 (at 25 °C) and a determined log Koc < 1.3 indicate low potential for adsorption to solid soil. Thus, a simulation test on biodegradation in soil does not need to be conducted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
