Additional information
In a guideline (OECD 202) and GLP study, LISEC (1999) reported a 48 -hr EC50 value of 7.3 mg/L (95% C.I. of 6-11.2 mg.L) for ENB in Daphnia magna. In a guideline (OECD 202) and GLP study, the Environment Agency of Japan (1999) reported a 48 -hr EC50 value of 3.34 mg/L (95% confidence limits:2.78-5.00 mg/L) for ENB in Daphnia magna, and a 48 -hr NOEC of 1.54 mg/L. The key parameter is drawn from the study for which the original report is available. This is not critical in determining the long term PNECs.
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.
