Additional information

One study is available investigating the short-term toxicity to the freshwater invertebrate Daphnia magna according to the OECD Guideline 202 (Sayers, 2009). The test species were exposed to 1.3, 2.5, 5.0, 10 and 20 mg/L of test substance under flow-through conditions. Chemical analysis of the test water solutions were performed throughout the test period to measure the actual test concentrations. Test item concentrations ranged from 72 – 110% of nominal. An EC50 of 11 mg/L was determined after an exposure of 48 h based on the mean measured concentrations.
