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:

 

Trophic level	Species	Parameter	Endpoint	Value (mg/L)	Reference
Acute toxicity, freshwater
Invertebrates	Daphnia magna	mobility	48-h EC50	0.8	Handlos, F. & Frank, C., 2013
Algae	Pseudokirchnerella subcapitata	growth rate	72-h EC50	5.93	Handlos, F. & Frank, C., 2013
Fish	Danio rerio	mortality	96-h LC50	1.41	Yaogao Shu, 2015
Chronic toxicity, freshwater
Algae	Pseudokirchnerella subcapitata	growth rate	72 -h EC10	4.24	Handlos, F. & Frank, C., 2013
Invertebrates	Daphnia magna	reproduction	21-d EC10	0.0807	Noack, M., 2015

 

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.
