Comments:
This was a limit test conducted at a nominal concentration of 100 mg/L. Exposure solutions were prepared as for the fish test - see 5.1.01.
No immobilisation was observed. Measured test substance concentrations were at or below the limit of quantification, 0.00613 mg/l at the start of the test. At the end of the test measured concentrations were all below the limit of quantification since no effects were observed,
48h EC50 > limit of solubility
48h NOEC > or = limit of solubility
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.
