Additional information

The endpoint of growth inhibition study aquatic plants is covered by a study conducted on Lemna minor.

A study was conducted on aquatic algae (scenedesmus subspicatus) but no details was available. Upon a 72 -hour exposure, an EC50 of 4.6 mg/l was found. The significance of such data could not be ascertained , due to the possible interference of the substance colouration on the test outcome. However, in the overall evaluation, such result appeared to be comparable to other available data, thus taken as a qualitative indication of aquatic toxicity.
