Additional information
The acute immobilisation of the test material to Daphnia magna (STRAUS) was determined according to OECD Guideline 202 / Commission Regulation (EC) No 440/2008.C.2. The study was conducted as a limit test under semi-static condition over a duration of 48 hours. 20 test organisms were exposed to the test concentration and control. The nominal test item concentrationwas 100 mg/L. A reference test is carried out 6 months prior to the test with potassium dichromate as reference item and the reference toxicity determined. The EC50 value of the reference item at 0.86 mg/L after 24 h was within the prescribed concentration range of 0.6 to 2.1 mg/L according toOECD Guideline 202. The validity criteria of the test guideline were fulfilled. The EC50 value was determined to be > 100 mg/L after 48 h and the NOEC was determined to be 100 mg/L after 48 h.
