Description of key information
The 48–hr-acute toxicity of the test item to Daphnia magna was studied under static conditions. The 48–hr EC50 was determined to be 42.6 mg/L effect concentration based on loading rate. Based on these findings no toxicity were observed within the water solubility limit of the substance.
Key value for chemical safety assessment
Additional information
The test substance was tested in the Acute DaphniaToxicity Test according to the OECD Guideline for the Testing of Chemicals No. 202 (April 2004) usingDaphnia magna(Straus) as test organism.
A loading rate-response test was performed at five loading rates of 1.71, 3.76, 8.26, 18.2 and 40 mg/L test item/L on order to comply with the requirements of the guideline. A clear laoding-rate-response relationship was observed. The effect concentrations (immobility of daphnids) are based on the laoding rates: EC50 (48h): 42.6 mg test item/L.
Based on these findings no toxicity were observed within the water solubility of the substance (WS: 8.37 mg/L).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
