Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic toxicity

The available reliable ecotoxicity results selected for the effect of the test substance on aquatic organisms are all based on dissolved test item concentrations at test start. The table below presents an overview of the reliable toxicity data:

Reliable short-term toxicity data for freshwater organisms are available for three trophic levels: fish, aquatic invertebrates and algae. The lowest acute effect value is the 48-h EC50of 0.56 mg/L observed for the effect of the test item on immobilisation of Daphnia magna.

 

Reliable long-term toxicity data for freshwater organisms are available for one trophic level: algae. The lowest chronic effect value is the 72-h EC10of 0.56 mg/L observed for the effect of the test item on growth rate of Desmodesmus subspicatus.

 

The 48-h NOEC value forDaphnia magnawas 0.112 mg/L.
