Short-term toxicity to aquatic invertebrates

Description of key information
The acute toxicity of the substance to Daphnia magna was determined by using the OECD guideline method 202 in a compliance with Good Laboratory Practice. Because the substance is a UVCB-substance, the exposure was expressed as the loading rate (mass to volume ratio of the mixture to medium) and the test concentrations were prepared as WAFs. The results were expressed as EL10- and EL50-values after 24 hours and 48 hours of exposure.
Key value for chemical safety assessment

Additional information
The acute toxicity of the substance toDaphnia magnawas determined by using the OECD guideline method 202 in a compliance with Good Laboratory Practice.
The substance is a UVCB- substance. Due to differences in partitioning behavior and water solubility between the components, it is difficult to achieve a homogeneous solution by direct addition of the test substance into the test medium. Therefore water accommodated fractions (WAFs) were prepared. The WAF of the multi-component substances contains only the fraction that is dissolved or present as a stable dispersion or emulsion. The exposure was expressed as the loading rate (mass to volume ratio of the mixture to medium). The WAF loading rates used in the study were the following: 6.25 mg/L, 12.50 mg/L, 25.00 mg/L, 50.00 mg/L and 100.00 mg/L. Based on the results the substance was showing adverse effects to D.magna immobilisation within the loading range of 10 -100 mg/L.
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.
