100 mg/L

Additional information

In a GLP compliant study, performed according to OECD Guideline 202, the acute toxicity of the test substance to 20 Daphnia magna was determined in a 48 hours static test (Solvias 2003). The nominal concentration were 4.3, 9.4, 21, 45, and 100 mg/L. The measured test concentrations in the analysed samples of 100 mg/L were 105% of the nominal values at the start and 107% at the end of exposure. Therefore, under test conditions the test article was sufficiently stable. No immobilisation of Daphnia was observed in the control and at any of the test item concentrations after 24 hours. After 48 hours of exposure, no immobilisation was observed at any of the treatments. Therefore, the EC50 was determined to be >100mg/L.
