Description of key information
Additional information
Biodegradation effect :
In water and sediment : Based on the Level III Fugacity Model, the half life period of difluoroacetic acid was estimated. The half life period of difluoroacetic acid in water is 8.7 days, therefore it is considered that the substance will qualiy as not persistent as the half life does not exceed the threshold of 60 days. So, it can be confirmed that the substance is readily biodegradable in water medium whereas in sediment the half life is 78 days and 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 sediment. However, it can be observed that difluoroacetic acid does not diffuse in the sediment medium since it's percentage in the sediment medium is reported to be 0% and hence persistence in the sediment compartment is not likely to be critical.
In soil : The PBT Profiler has estimated that difluoroacetic acid is expected to to be found predominantly in soil and its persistence estimate is based on its availablility in this medium. Its half life in soil is found to be 17 days (408 hours ) which does not exceed the EPI criteria of >= 2months and (<= 6 months ). Therefore, difluoroacetic acid is estimated to be non persistent in the soil environment.
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.
