Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:-
4-nitroanilineis 50% biodegradable in water in 38 days (half-life) indicating 4-nitroanilineis readily biodegradable in water.
Biodegradation in water and sediment:
Based on the Level III Fugacity Model, the half life period of the4-nitroanilinewas estimated. The half period of4-nitroanilinein water is 912 hrs (38 days) therfore it is considered that the substance will qualify as not persistent as the half life does not exceed the EPA criteria of 60 days. So, it can be confirmed that the substance is readily biodegradable in water medium where as in sediment the half life is 8160 hrs (340 days). Based on this value, it can be inferred that the substance is persistent in sediment medium and is not readily biodegradable probably due to the anaerobic conditions existing in most sediments. However, it can be observed that4-nitroanilinedoes not diffuse in the sediment medium since it's percentage in the sediment medium is reported to be 0%.
Biodegradation in soil:
Based on the Level III Fugacity Model the half life period of the4-nitroanilinewas estimated. As per the values it was observed that in general4-nitroanilinepersistence time is 1680 hr. The half life period of4-nitroanilinein soil is 1800 hrs and based on this value it is indicated that the chemical is persistent in soil medium.
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.
