Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
Acutely harmful for aquatic invertebrates.
Key value for chemical safety assessment
Additional information
The toxicity to aquatic invertebrates was assessed in a study conducted according to OECD 202 under consideration of GLP. As demonstrated in preliminary tests, the substance' concentration in the test medium was maximized with a shaking time of 1.5h. Longer shaking times resulted in lower concentrations. The daphnids were exposed to the water soluble fractions for 48h. As the substance is a UVCB the effect concentrations were based on nominal loading rates. The EL50 was determined at 18 mg/L. The NOEL and LOEL at 3.13 and 6.24 mg/L, respectively.
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.
