Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Four experimental studies provide consistent fish acute toxicity data. The lowest value out of the three available 96h-LC50 results is used as the key value. 96h-LC50 = 17.6 mg/L
Key value for chemical safety assessment
Fresh water fish

- Dose descriptor:

Additional information
Two experimental acute toxicity data are available in the literature: Broderius and Kahl (1985, 1995) have reported a 96h-LC50 equal to 37.9 mg/L in Pimephales promelas (fathead minnow) and Bengtsson-Be et al (1979, 1984) have described a 96h-LC50 equal to 45 mg/L in Alburnus alburnus (bleak). In addition, an OECD 203 compliant GLP study report is available for medaka, with an 96h-LC50 equal to 17.6 mg/L. This value was selected as the key value for chemical safety assessment.
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.
