- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
Additional information
“The biodegradability of the test material has been evaluated in the OECD 301C, D, and F tests of ready biodegradability. In the CO2 evolution (301B) and Manometric Respirometry (301F) tests, the substance was shown to be toxic/inhibitory to the inocula used, at concentrations of 10 mg Carbon/L (OECD 301B) and 34 mg/L as test substance (OECD 301F). In the Closed-Bottle Test (301D), an initial concentration of 2 mg/L as test substance exhibited 22% biodegradation based on biological oxygen demand (BOD) after 28 days. Based on this result, the substance can be regarded as exhibiting inherent (primary) biodegradability.
The standard ready biodegradation study results did not allow for the characterization of “readily biodegradable” due to some degree to toxicity of the test material to the microbial inoculum and study relevant concentrations. There have been numerous studies that have demonstrated toxicity of aliphatic amines at test substance concentrations that are typical for screening assays of biodegradation. Numerous data in the literature have shown that when these aliphatic amines are tested for biodegradability at test concentrations at environmentally realistic concentrations (typically below the toxicity threshold) that biodegradation does occur. Model predictions from EPIWIN QSAR predicts that this test material will biodegrade rapidly. Based on the measured biodegradation data, the potential for microbial toxicity of the aliphatic amines at typical screening level test substance concentrations, the general biodegradability of linear and branched aliphatic hydrocarbons and finally the QSAR estimates, the weight of evidence indicate that the test material is not persistent.
Based on the structures of the substance components, the complete biodegradation of the substance would be expected to occur at the very low (and non-inhibitory) concentrations which may occur in the environment. Thus, the test material would not be expected to be persistent in the environment.”
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).
