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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
Hydrolysis
The DT50 values (25 °C) for the test substance were 245, 301 and 235 days at pH 5, 7 and 9, respectively.
Biodegradation
Biodegradation in water: screening tests
No study on ready biodegradability is available. For risk assessment purposes a conservative approach is taken and the test item is considered as not readily biodegradable (worst case).
Biodegradation in water and sediment: simulation tests
The substance is degraded and mineralised in aerobic water/sediment systems (DT50 in the range of 9.3 to 111 days). The DT50 in the water layer is expected to be in the range of 3.6 to 7.9 days.
Transport and distribution
Adsorption/desorption
The adsorption properties of the test substance were studied in five soils using the batch equilibrium method in accordance with OECD TG 106 and US EPA OPPTS 835.1230. The Koc (20 °C) of Fenamiphos is determined to be 106.6 mL/g (geometric mean).
Additional information
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.
