Additional information
A study was conducted to determine the acute toxicity of the test substance to the freshwater fish, Danio rerio (zebra fish) under semi-static conditions according to the OECD Guideline 203 in compliance with GLP. In this study, the fish was exposed to the test substance at the nominal threshold concentration (TC) of 0.11 mg/L. The TC was based on the results of an algae study with this substance. Chemical analysis of the test concentrations was carried out in old and new solutions. Recoveries did not remain above 80% of the nominal concentrations. A geometric mean measured concentration was therefore calculated and used for endpoint determination. All critical validity criteria were met. No lethal or sub lethal or behavioral effects of any kind were observed in the test concentration. No mortality occurred in control also. Under the test conditions, the 96 h LC50 of the test substance was greater than the threshold concentration of 25.8 µg/L (geometric mean measured concentration).
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.
