Description of key information
A long-term study in Daphnia magna with the source substance showed that the 21-d NOEC is >= 0.8 mg/L, based on mean measured concentration. No statistical significant effects on reproduction and mortality at highest concentration tested (nominal 1 mg/L, mean measured 0.8 mg/L).
Key value for chemical safety assessment
Additional information
Executive summary of the study performed with the source substance:
The chronic toxicity of Aquapel 364 has been determined for Daphnia magna according to the OECD guideline (211). The test substance was solved using a vehicle (acetone) and the test was semi static. 10 daphnids were used per concentration level, each housed individually. Concentrations tested ranged from nominally 0.056 - 1.0 mg/L, however actual concentrations varied from 57%-290% of nominal. Some mortality (up to 20%) was observed, but not dose-dependent. No significant effects were determined for reproduction or length. The overall no observed effect concentration was > = 0.8 mg/L and the overall lowest observed effect concentration was > 0.8 mg/L based on mean measured 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.
