Description of key information
Poorly biodegradable. Not readily biodegradable (according to OECD criteria).
Key value for chemical safety assessment
- Biodegradation in water:
- not biodegradable
- Type of water:
- freshwater
Additional information
Biodegradation of 4-nitrotoluene-2-sulphonic acid was determined according to OECD Guideline 301C and 301E using a mixture of sewage, soil and natural water as well as effluent from laboratory sewage treatment plant, respectively. The result showed a degradation rate of 3 % and 0 % after 28 days and 29 days, respectively. Therefore, the test substance is poorly 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.
