Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A summary of information available on the biodegradation in water was provided in ECETOC’s JACC Report #53:Cyanides of Hydrogen, Sodium and Potassium, and Acetone Cyanohydrin (CAS No. 74-90-8, 143-33-9, 151-50-8 and 75-86-5), 2007, No. 53: 115-116. This summary includes evidence of cyanide biodegradation by southern bulrush (Scirpus californicus) in a plant marsh filter system; water hyacincth (Eichhornia crassipes) in batch test solutions; basket willow (Salix viminalis); and in 28 species of Chinese flora, including Chinese elder (Sambucus chinensis) showing a removal rate of 8.77 mg CN-/kg/h. Specific information on biodegradation in sediments was not available. Half-life values in water and sediment were not derived.
Key value for chemical safety assessment
Additional information
Information was not sufficient for the determination of cyanide half-life values in water or sediment.
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.
