Description of key information

Chronically very toxic to aquatic organisms based on long-term toxicity data.
NOEC (21d) = 0.1 mg/L and LOEC (21d) = 0.32 mg/L (nominal) for Daphnia magna (OECD 211)

Key value for chemical safety assessment

Additional information

The chronic aquatic toxicity on aquatic invertebrates was investigated in a GLP guideline study according to OECD 211 under semi-static test conditions with Daphnia magna as test species. Based on the low water solubility of the test item, saturated stock solutions were prepared. After 21 days of exposure the NOEC was determined to be 0.1 mg/L and the LOEC 0.32 mg/L (nominal) [Eurofins, 2013].
