Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

LD50>100 mg/L, 24h, rainbow trout, no guideline, Hutchings 2004
Key value for chemical safety assessment
Additional information
The acute aquatic toxicity of the test substance to rainbow trout (Oncorhynchus mykiss) was tested in a non-GLP study under static conditions for a period of 24 hours. The testing duration of 24 hours deviated from the 96 hours standard test duration specified in the relevant OECD or EC guidelines. A single test vessel was prepared as a control of dilution water containing no substance and one test vessel was prepared for each of the nominal test concentrations of 0.01, 0.1, 1.0, 10 and 100 mg/L. Five fish were randomly assigned to each of the control or test vessels. Animals were not fed during the course of the study and were kept at 15 °C ± 1 °C at a light cycle of 16 hours light, 8 hours dark (with 20 minutes of dawn and dusk transition periods). No mortality was observed up to the highest nominal test concentration of 100 mg/L and the LC50 value after 24 hours hence is greater than 100 mg/L. No adverse effects were reported up to the nominal test concentration of 100 mg/L and the NOEC value after 24 hours hence is 100 mg/L.
The available data is considered relevant, but not to be reliable or adequate for risk assessment or classification and labelling purposes. This endpoint is not considered complete or conclusive.
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.
