Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
DT50 = 137 days
Key value for chemical safety assessment
- Half-life in soil:
- 137 d
Additional information
The degradation of the test item in soil was investigated under aerobic standard conditions at 20 °C and a soil moisture of 40 % of the maximum water holding capacity. The application rate was 140 ug/kg soil.
The soil was extracted with acetonitrile + water and the extracts were analysed separately by high-performance liquid chromatography (HPLC) and mass spectroscopy (LC-MS).
The test item was degraded in soil. The DT-50 value (half-life) in the soil "Monheim 3" was calculated to be 137 days following first order reaction kinetics.
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.
