Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Studies conducted in accordance with US EPA standard (and compliant with EU and OECD guidelines) on 4 species of fish: Fathead minnow , Bluegill sunfish, Sheepshead minnow or Rainbow trout.
The test with bluegill sunfish (Lepomis macrochirus) was performed in static conditions. No solvent was used and care was taken to avoid remaining floating test chemical. The reported 96 h LC50 value (0.48 mg/L) was based on measured test concentration.
As the study was performed according to standards and GLP procedure but no detailled information were given in the publication, therefore, the results are considered as reliable with restriction.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 0.48 mg/L
Additional information
Short-term toxicity studies for fish are also summarised in EU RAR, where the lowest observed LC50 for fish was reported as 0.35 mg/L for Perca flavescens under flow through condition (Mayer and Ellersieck, 1986). This result is similar as the lowest observed LC50 value (0.48mg/L) in 96 hours test with bluegill sunfish.
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.
