Description of key information
Additional information
Biodegradation has been tested in a test and showed that the DOC disappeared very quickly. Nevertheless, the documentation of the study is limited and sufficient details are missing. Further a study has been cited, which showed no biodegradation of the test substance, but the documentation is limited. Hence both studies cannot be used for assessment. A review reported that an enzyme of Arthrobacter HA1 can utilize 1,4-dichlorobutane as substrate and convert it to a monohaloalkane, demonstrating that degradation of the test substance is possible. Further source is a study on biodegradation, commissioned by the Japanese Government, which is available on the homepage of the Incorpoarted Administrative Agency, National Institute of Technology and Evaluation. However, the details of study are not clear.
Therefore, in regards to classification and labeling, the test substance should be considered as not readily biodegradable.
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.
