Reliable short-term toxicity data for freshwater organisms are available for three trophic levels: aquatic invertebrates, algae and fish.

The lowest acute effect value was a 48-h EC50of 0.8 mg/L observed for the effect of the test item on immobilisation of Daphnia magna. The 48-h NOEC value for Daphnia magna was 0.31 mg/L.

The other two acute toxicity data are available for algae, with the acute effect 72-h EC50 value of 5.93 mg/L for Pseudokirchnerella subcapitata, and for fish, with the acute effect 96-h LC50 value of 1.41 mg/L for Danio rerio.

Reliable long-term toxicity data for freshwater organisms are available for two trophic levels: algae and aquatic invertebrates.

The chronic effect value for algae was a 72-h EC10 of 4.24 mg/L observed for the effect of the test item on growth rate of Pseudokirchneriella subcapitata.

The chronic effect value for aquatic invertebrates was a 21-d EC10 of 0.0807 mg/L observed for the effect of the test item on reproduction of Daphnia magna.
