Additional information

In a static test performed by Ökolimna (1991, non GLP) according to a German guideline (DIN 38412 Part 9), an EC50 (72h) of 75.9 mg/l based on Chl-a fluorescence yield measurements was determined for Scenedesmus subspicatus (nominal concentration). A conversion of these Chl-a fluorescence based data set, resulted in an EC50 (72 h) of 129.1 mg/l for growth rate.
