Key value for chemical safety assessment

Additional information

Toxicity to algae and cyanobacteria has been tested with Desmodesmus subspicatus over a 72 hour period at 100 mg/l. No effects were observed and the 72 hour EC0 > 100 mg/l. The measured concentrations correspond to 84% and 83 -85% of nominal values at 0 and 72 hours, respectively.
