Description of key information

ErC50 (72 h) > 0.085 mg/L (geometric mean measured concentration, OECD 201, Pseudokirchneriella subcapitata)

EC50 (48h) = 0.10 mg/L (Daphnia magna; OECD 202; arithmetic mean)

Additional information

Two studies are available, which assessed the aquatic toxicity of the substance on two different trophic levels (aquatic invertebrates and algae). The studies were performed according to international guidelines and GLP.

The effect values for both trophic levels were within a comparable range of toxicity: > 0.085 mg/L ErC50 (72h) for algae (based on geometric mean measured concentrations) and 0.10 mg/L EC50 (48h) for Daphnia (based on arithmetic mean).
