Additional information
One long-term toxicity to aquatic invertebrates study is available: a 21-day Daphnia reproduction study, conducted in accordance with GLP and OECD Test Guideline 211. Due to the poor water solubility of the test substance, test waters were prepared as water accomodated fractions (WAFs) of the test substance at nominal loading rates of 0, 0.954, 3.05, 9.77, 31.3 and 100 mg/litre. Concentrations of the test material itself were not quantified but total organic carbon (TOC) analysis was employed.
No 21-day EL50 could be determined since there were no statistically significant differences in any of the endpoints measured at any concentration. The NOELR was 100 mg/litre (nominal), the highest loading rate tested. TOC concentrations were similar in all test mixtures and the control (1.4-1.7 mg/litre).
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.
