Short-term toxicity to aquatic invertebrates
Administrative data

Description of key information
With high probability acutely not harmful to aquatic invertebrates. No acute toxic effects occur within the range of solubility.
Key value for chemical safety assessment
Additional information
One GLP guideline study on the toxicity of the substance to Daphnia magna is available (RCC Ltd. 2002c). Due to the low water solubility of the test item, a supersaturated dispersion of the test item with a loading rate of 100 mg/L was tested. The undiluted filtrate with the maximum concentration of dissolved test item was used as the test medium in a static test system set up according to OECD guideline 202. In the control and at the loading rate of 100 mg/L no immobilization or other signs of intoxication were determined during the test period of 48 hours.Therefore, an EC50 > 100 mg/l based on the loading rate was determined after 48 hours.
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.
