Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation in water
5-nitrovanillin was estimated to be 50% biodegradable in water in 38 days (half-life) indicating that 5-nitrovanillin is readily biodegradable in water since the half life is less than the threshold of 60 days (to qualify the chemical as persistent)
Biodegradation in water and sediment
Half life period of 5-nitrovanillin in water was observed to be 38 days while in sediment it is 340 days.Based on these half life values it is concluded that 5-nitrovanillin is readily biodegradable in water where as it is non biodegradable in sediment. However, since there is no diffusion of the substance in the sediment as evident from the reported data (0% in sediment) and hence persistence in the sediment compartment is not likely to be critical.
Biodegradation in soil
Half life period of 5-nitrovanillin in soil was observed to be 75 days (1800 hrs ). Based on these half life values it is concluded that 5-nitrovanillin is readily biodegradable (not persistent) in soil since the half life period of 5-nitrovanillin does not exceeds the threshold criteria (to qualify the chemical as persistent)
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.
