A test was performed following OECD 221.
The results show that the tested item had some toxic to Lemna minor with EC50 = 47.1 mg/L.
Lemna minor is an aquatic plant that develops his leaves on the surface of the water, while nourishing substances are taken from the water solution. With this tests the observed effect is only related to the potential toxicity of the substance and not to the potential shading effect of a classical Alga study.
