The effects of the test item on the growth of the monocotyledonous aquatic plant species Lemna gibba were determined according to the principles of OECD 221.
Lemna gibba was exposed to the test item for 7 days under semi-static conditions. 5 nominal test item concentration levels in a geometrical series with a dilution factor of 2:20.0 - 40.0 - 80.0 - 160 - 320 mg/L were used..
The measured concentrations of the test item at the start and the end of the exposure in the dose-response test were in the range of 96 to 103% and 73 to 102% of the nominal values, respectively. All effect values are given based on the nominal test item concentrations
