Description of key information
Additional information
2,2'-dimethyl-2,2'-azodipropiononitrile is not readily biodegradable, and has shown less than 10 % degradation in the 28 days biodegradation test (OCDE 301 B).
The aerobic biodegradation of [14C]-2,2'-dimethyl-2,2'-azodipropiononitrile has been studied in the laboratory at two concentrations (1 and 10 µg/L) in natural surface water, under dark conditions at 20 ± 2°C (OECD 309). Under these conditions, AZDN mineralised slowly with = 5% carbon dioxide formed within 60 DAT. Some degradation occurred within the water phase and at 60 DAT up to ca 11% of the applied AZDN was present as degradation products. The maximum level of any single degradation product was 6% applied radioactivity (AR). The DT50 for AZDN in the water (OECD 309), determined by SFO kinetics, was 259 days at 1 µg/L and 950 days at 10 µg/L.
No additional investigation is proposed for sediment or soil because they are not considered as the compartments of concern based on the intrinsic properties of the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
