Additional information

Acute toxicity of mesityl oxide to fish has been determined according to OECD 203. Based on the test results the 96 hour LC50 of Mesityl Oxide for Zebrafish (Danio rerio) was determined to be 72.93 mg test item/L based on nominal concentrations. The no observed effect concentration (NOEC) was determined to be 45.5 mg test item/L and the LOEC was determined to be 100 mg test item/L, both values also based on nominal concentrations.
