Description of key information
In an acute toxicity test with Danio rerio, an 96h-LC50 >1.27 mg/L (geometric mean measured concentration) was observed (BASF, 140926BZ/FAZ17034, 2016).
Key value for chemical safety assessment
Additional information
An acute fish toxicity was conducted with Danio rerio (zebrafish) according to OECD guideline 203 (BASF, 140926BZ/FAZ17034, 2016). This semi-static test was performed as a limit test with a nominal threshold concentration of 2.50 mg/L (loading). The test substance concentration was analytically verified via GC-MS. The measured concentrations in freshly prepared media (0 h) were 60 and 75% of the nominal values. In corresponding 24 h aged test media, the measured concentrations were 34 and 44% of the nominal values. Therefore, all effect values are based on the geometric mean measured concentrations of the test item. The tested threshold concentration of 2.50 mg/L corresponds to the geometric mean measured concentration of 1.27 mg/L. After an exposure period of 96 hours, the limit concentration of this test was found to have no lethal effects on zebrafish. Thus, the LC50 was >1.27 mg/L (based on mean measured concentration).
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.
