Additional information
The acute toxicity of the test material to aquatic invertebrates was investigated inDaphnia magnain accordance with the standardised guidelines EPA OPP 72-2 and EPA OTS 797.1300. During the test the daphnia were exposed to the test material at nominal test concentrations of 0, 130, 220, 360, 600 and 1000 mg/L under static renewal conditions; all tests were conducted using water soluble fractions. Based on the nominal concentrations of test material, the 48 hour EC50 value and corresponding 95% confidence interval were determined to be 540 (430 - 660) mg/L. The No Observed Effect Concentration was determined to be 220 mg/L. The study was performed in line with GLP and accepted standardised guidelines with a high standard of reporting. However, it is scored a Klimisch 2, reliable with restriction, based on potential solubility issues in the preparation of the test material solution.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
