Description of key information
With high probability acutely not harmful to fish. No toxic effects occur within the range of solubility
Key value for chemical safety assessment
Additional information
A study was performed (RCC Umweltchemie AG 1996a) according to OECD guideline 203 using zebra fish and a supersaturated stock suspension in a limit test of 100 mg/L (mean measured concentration: 0.032 mg/L). The stock suspension was continuously stirred at room temperature in the dark over 2 hours and then filtered. Only the undiluted filtrate with the maximum concentration of dissolved respectively very fine dispersed test substance was used as the test medium.
The 96 -hour NOEC and the 96-hour LC0 were determined to be at least at the loading rate of 100 mg/L (0.032 mg/L mean measured). The 96 -hour LOEC and the 96 -hour LC50 were clearly higher than the loading rate of 100 mg/L (0.032 mg/L mean measured). No mortality or visible abnormalities were observed during the test period of 96 hours. Therefore, the test substance is with high probability acutely not harmful to fish. No acute toxic effects occur at the range of solubility.
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.
