Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Two studies addressing phototransformation in water were conducted with the following results obtained:
Wolt JD, Woodburn K, Chari S, Shepler K & Ruzo LO (1991a): The actual and extrapolated half-life of light-exposed Flumetsulam is approximately 164 days (R=0.86) and 326 days (R=0.53) at pH5 and pH7, respectively.
Wolt JD, Woodburn K, Chari S, Shepler K & Ruzo LO (1991b): The extrapolated half-life of light-exposed Flumetsulam was approximately 151 days and 727 days at pH 5 and 7, respectively.

Key value for chemical safety assessment

Additional information

Both available studies were of equal reliability but gave different results. Therefore, neither study was selected as key information, but are instead provided as supporting data. As this endpoint is not mandatory for a REACH registration, this is considered to be an acceptable approach.
