Additional information

The toxic effect of the test item to Danio rerio according to OECD 203 was assessed in a semi-static dose-response test in a loosely covered glass-aquaria. For the determination of the test concentrations one range-finding test was performed. The test concentrations were verified by GC-FID analysis. At the end of the test the toxicity of the test item to Danio rerio had increased. After 96 hours of exposure no mortality and no effects on behaviour of the test animals was observed in the controls and in the measured (geometric mean) test item concentration of 0.33 mg test item/L.

At the measured (geometric mean) concentration of 4.27 mg test item/L, 7 out of 7 died (LC100).

 

The 96-hour LC50 was determined to be 2.64 mg test item/L based on geometric mean measured concentration.
