Any other information on results incl. tables
The LC50 values were observed in the range of 1800 - 3200 mg/L. When the test solutions were corrected for pH and oxygen content, LC50 values were observed between 5600 and 10000 mg/L.
Applicant's summary and conclusion
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.
