Description of key information

In the table below the acute aquatic toxicity data are summarised

 Species  Guideline  Result in mg/l


Pseudokirchneriella subcapitata


EC50 growth rate > 0.31

based on geometric mean measured concentrations

Key study, Rel. 1. No robust EC10-value could be determined for growth rate. The ErC50 is >0.31 mg/L based on the fact that only 21% inhibition of growth rate was observed at this concentration.

 Daphnia magna

 OECD TG 202

 EC50 48h = 0.33

 based on mean measured concentrations


Key study, Rel 1.

Additional information

In the study with algae, the geometric mean measured concentrations showed no dose-response curve due to the fact that average exposure concentrations were similar at the three lowest WAFs, i.e. 0.026-0.044 mg/L and at the three highest WAFs (0.31-0.41 mg/L).
