Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Environmental exposure with Fluometuron has been assessed widely by EFSA (EFSA.europa.eu) as Fluometuron is a well known active ingredient for herbicides. In respect to industrial and/or professional uses only small amounts will be emitted into environment in comparison to agricultural uses, as only one application is identified with a limited number of sites (< 10)

Fluometuron is very toxic to aquatic algae organisms with a lowest NOEC of 0.061mg/L. This has to be taken into account for every exposure scenario as a main risk. In respect to fish and aquatic invertebrates considerably higher NOEC were found with 9.0 and 6.6 mg/L respectively. Against aquatic microorganisms no significant effects were observed neither in respiration inhibition test nor in closed bottle test. The risk to the function of waste water treatment plants is low.

Conclusion on classification

Due to the toxic effects on algae, EC50 of 0.32 mg/L (ErC50 = 0,92 mg/L) and NOEC of 0.0661 mg/L, Fluometuron has to be classified as aquatic acute toxic category 1 (H400) and aquatic chronic category 1 (H410) according to regulation 12727/2008.

Fluometuron is considered not to be hazardous for the ozone layer as Fluometuron is a non-volatile solid.
