Additional information

One study is available, testing the short term toxicity of the substance to aquatic invertebrates and was performed according to the OECD guideline 202 and GLP. The water flea, Daphnia magna was exposed to nominal test item concentrations of 5, 10, 20, 40 mg/L and a control for 48 h. A static freshwater system was chosen for testing. The test item was monitored during the study via TOC analysis. The analytical recoveries were > 80% of the nominal values. The test item caused biological effects to Daphnia magna and resulted in an EC50 (48 h) of 11.3 mg/L (geom. mean meas.). The EC50 (48 h) of 11.3 mg/L (geom. mean meas.) was derived from the EC0 (48 h) = 6.8 mg/L and EC100 (48 h) = 18.8 mg/L.
