Reliable short-term toxicity data for freshwater organisms are available for two trophic levels: aquatic invertebrates and algae. The lowest acute effect value was a 72-h EC50of 16.0 mg/L observed for the effect of the test item on growth rate of Pseudokirchneriella subcapitatus. Acute toxicity data are also available for invertebrates, with the lowest acute effect 48-h LC50value of 43.2 mg/L for Daphnia magna.

Reliable long-term toxicity data for freshwater organisms are available for one trophic level: algae. The lowest chronic effect value was a 72-h EC10of 2.19 mg/L observed for the effect of the test item on growth rate of Pseudokirchneriella subcapitatus. The NOEC value for Pseudokirchneriella subcapitatus is 3.20 mg/L (72-h).
