Description of key information

EC50 (48 h) Daphnia magna = 8.37 mg/L (geometric mean measured, OECD 202)

ErC50 (72 h) Pseudokirchneriella subcapitata = 21.3 mg/L (geometric mean measured, OECD 201)

ErC10 (72 h) Pseudokirchneriella subcapitata = 16.1 mg/L (geometric mean measured concentration, OECD 201)

Additional information

Experimental studies evaluating the toxicity of the substance to aquatic organisms are available for two different trophic levels (aquatic invertebrates and algae).

The studies were performed according to international guidelines and GLP. Daphnia magna turned out to be the more sensitive species with an EC50 (48 h) of 8.37 mg/L based on mobility of the test species. Testing with aquatic algae resulted in an ErC50 (72 h) of 21.3 mg/L and an ErC10 (72 h) of 16.1 mg/L. All effect values were based on the geometric mean measured concentrations.
