Description of key information

In a 48-h acute toxicity study, water fleas (Daphia magna) were exposed to B508 at nominal concentrations of 0 (dilution water control), 0.63, 1.3, 2.5, 5, 10, 20 and 40 mg/L under semi-static conditions. 
Due to the poor water solubility of B508 the choice of a test setup with semi-static conditions was considered appropriate.
The EC50 value was 0.54 mg/L (as calculated from measured TOC concentrations).
The present toxicity study is classified as reliable with restrictions, because the results were calculated based on measured TOC concentrations which are non-discriminative by nature.
