Additional information
The toxicity test (key_Toxicity to aquatic algae and cyanobacteria_2014_Rel1) of aquatic algae performed according to OECD 201 (2011) and GLP was rated with RL=1 (reliable without restrictions) and used as key study.
In this study no inhibition on the growth of the freshwater green alga Desmodesmus subspicatus was found after 72 hours exposure to the test item in a limit concentration of 100 mg/L. The EC10- and EC50-values for inhibition of growth rate and yield after 72 hours were > 100 mg/L, respectively. The NOEC for inhibition of growth rate and yield after 72 hours were ≥ 100 mg/L.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
