Description of key information
The effect of an analog of this substance, EC 283-392-8, on the reproduction of Daphnia magna was assessed over a 21-day period and the data was suitable for read across. The NOECs were 0.4 mg/L nominal for reproduction and 0.8 mg/L nominal for both daphnid length and daphnid weight.
Key value for chemical safety assessment
Fresh water invertebrates

- 0.4 mg/L
Additional information
Since tests on chronic toxicity of the UVCB substance itself to aquatic invertebrates are not available, a conclusion by analogy approach according to Annex XI of REACH has been applied.
The effect of an analog of this substance, EC 283-392-8, on the reproduction of Daphnia magnawas assessedover a 21-day period. The NOECs were determined to be 0.4 mg/L nominal for reproduction and 0.8 mg/L nominal for both daphnid length and daphnid weight. The LOECs were 0.8 mg/L nominal for reproduction and >0.8 mg/L nominal for daphnid length and daphnid weight.
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.
