Description of key information

Based on a weight-of-evidence approach with several different compositions of the test item, the 96 -h LC50 for fish (Danio rerio) was determined thrice at >100 mg/L. The other studies were not taken into account due to some major methodological deficiencies (cold water species, short exposure time, disputable test concentration range). The substance is not acutely toxic to fish up to 100 mg/L and beyond.

Key value for chemical safety assessment
