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 two trophic levels: aquatic invertebrates and algae.The lowest acute effect value was the 48-h EC50 of 21.7 mg/L observed for the effect of the test item on immobilisation of Daphnia magna. The 48-h NOEC value for Daphnia magna was 10.0 mg/L.

Reliable long-term toxicity data for freshwater organisms are available for one trophic level: algae. The chronic effect value for algae was a 72-h EC10 of 16.5 mg/L observed for the effect of the test item on growth rate of Pseudokirchneriella subcapitata.

All results based on nominal test item concentrations.
