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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
