No effects were observed up to the highest concentration tested (100 mg/l nominal concentration.

Key value for chemical safety assessment

Additional information

Toxicity to algae and cyanobacteria has been tested with Desmodesmus subspicatus over a 72 hr period at 100 mg/l. No effects were observed and the NOEC / EC0 (biomass and growth rate) are >=100 mg/l (nominal concentration) and 83.8 m/l (measured concentration).
