Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: screening tests
The screening test inherent to the biodegradability of the substance was calculated using the software BIOWIN v4.10.
The results indicate that picramic acid is not expected to be readily biodegradable.
The half-life of the substance, picramic acid is predicted 37.5 days using the Level III Fugacity model. This indicates that the substance is expected to be non-persistent in water.
Biodegradation in water and sediment: simulation tests
Half life period of picramic acid in water is observed to be 37.5 days (900 hrs.) while in sediment it is 337.5 days (8100 hrs). Based on these half life values of picramic acid, it is concluded that the chemical is not persistent in water and persistent in sediment.
Biodegradation in soil
EPI Suite has estimated that picramic acid is expected to be found not predominantly in soil and its not persistence estimate is based on its transformation in this medium. Its half-life in soil, 75 days (1800 hrs), does exceeds the threshold of 120 days as per Annex XIII of REACH.
Therefore, picramic acid is estimated to be not 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.
