Description of key information

ZEH 2017 did not induce acute immobilisation of Daphnia magna at a loading rate of 50 mg/L after 48 h of exposure (NOEC). The 48 h EL50 was > 100 mg/L

Additional information

A study was conducted to assess the acute toxicity of the test substance toDaphnia magnain accordance with OECD Guideline 202, the test methods of Commission Regulation (EC) No 440/2008, Part C.2, 2008, the ISO International Standard 6341 and the OECD series on testing and assessment No. 23, 2000. Twenty daphnids per concentration (four replicates, five daphnids per replicate) were exposed to concentrations of 6.25, 12.50, 25, 50 and 100 mg/L.The total test period was 48 h and samples for analytical confirmation of actual exposure concentrations were taken at the start and the end of the test. These concentrations remained stable during the test period. The test substance did not induce acute immobilisation of Daphnia magnaat a loading rate of 50mg/L after 48 h of exposure. The 48 h EL50 was > 100 mg/L.
