Additional information
A study conducted according to OECD guideline 203 is available. Zebra fish were used as test organisms and the LC50 after 96 hours of exposure was determined to be 38 mg/L. The results were based on the initially measured test item concentrations, solvents or dispersants were not used. The NOEC was determined to be 27 mg/L.
Additionally, as a range finding test for a bioaccumulation study zebra fish were tested according to OECD guideline 203. The determined LC50 (96 h) value was 9.6 mg/L based on measured test item concentrations. However, the test was performed using a dispersant (HCO-80) and mortality was observed in the dispersant control. Further, though the effect concentrations were expressed based on measured data, it was not further specified whether these values were initially or mean measured or if time weighted average values were used. Therefore, this test was not considered suitable as key study.
Furthermore, a screening test was conducted according to OECD guideline 203 with 1, 10 and 100 mg/L. The lowest test concentrations did not show any mortality, whereas 100 % mortality was observed at the highest test concentration (100 mg/L).
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.
