Endpoint summary

Additional information

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

Trophic level	Species	Parameter	Endpoint	Value (mg/L)	Reference
Acute toxicity, freshwater
Invertebrates	Daphnia magna	mobility	48-h LC50	44.4	Noack, 2012
Algae	Scenedesmus subspicatus	growth rate	72-h EC50	7.55	Scheerbaum, 2012
Chronic toxicity, freshwater
Algae	Scenedesmus subspicatus	growth rate	72 -h EC10	3.22	Scheerbaum, 2012

 

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 7.55 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 44.4 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 3.22 mg/L observed for the effect of the test item on growth rate of Pseudokirchneriella subcapitatus.

The NOEC value for daphnia magna is 35.6 mg/L (48-h test) and NOEC value for Pseudokirchneriella subcapitatus is 1.27 mg/L (72-h test).
