Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Aniline is a commonly used reference substance for degradation tests. As such, there are several experimental studies on the readily biodegradability available, demonstrating that Aniline is readiliy biodegradable (according to OECD criteria). Furthermore, in surface water biodegradation studies, primary degradation and mineralization was measured using environmentally relevant test substance concentrations. Degradation rates of > 80% were measured within a few days underlining the readily biodegradability of aniline. In sediment and soil, two competing processes are at hand, biodegradation and the formation of non-hydrolyzable covalent bonds to humic substances. This binding leads to long half lifes for bound aniline of 350 and 3500 days for soil and sediment, respectively. In EU-Risk Assessment report (2004) it was assumed that approximately, 80% of Aniline is covalently bound in soil. Measurements in sediment tests gave a similar observation.
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.
