Description of key information
The acute toxicity of the test material (CAS 4259 -15 -8) to the freshwater invertebrate Daphnia magna has been investigated in a GLP compliant study according to OECD Guideline 202. The quality of the study was assessed with Klimisch 2. A 48-h EL50 value of 75 mg/L nominal loading rate with 95 % confidence limits of 65 to 87 mg/L was obtained. The No Observed Effect Loading rate was 32 mg/L nominal loading rate.
The acute toxicity of the test material (CAS 84605 -29 -8) to the freshwater invertebrate Daphnia magna has been investigated in a GLP compliant study according to OECD Guideline 202. The quality of the study was assessed with Klimisch 2. A 48-h EL50 value of 23 mg/L nominal loading rate with 95 % confidence limits of 20 to 25 mg/L was obtained. The No Observed Effect Loading rate was 10 mg/L nominal loading rate.
The values for both substances slightly differ, but this is in range with the category approach, where nevertheless the members of one category may have different values.
For CSA the lower value is choosen as worst-case-approach .
