Description of key information
LL50(96h) > 100 mg/L (nominal, loading rate) for mortality of Danio rerio (OECD 203)
Key value for chemical safety assessment
Additional information
One study investigating the short-term toxicity of the test substance to freshwater fish is available. The study was performed according to GLP and OECD guideline 203 using Danio rerio as test organism (Rzodeczko 2018). A loading rate WAF of 100 mg/L was tested in a limit test. TOC analysis indicated the suitability of using nominal concentrations. No mortality was obswerved in the control and the treatment. Thus, the 96h-LL50 value is determined to be > 100 mg/L based on nominal concentrations.
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.
