Description of key information

With high probability acutely not harmful to algae, no toxic effects occur in the range of water solubility.

Key value for chemical safety assessment

Additional information

In an algae study (72 h) according to OECD 201 no inhibition of algae growth, expressed as biomass and growth rate was observed at the highest test concentration of 100 mg/L nominal (CIBA-GEIGY 1995a). The mean measured concentration (0.072 mg/L) of the test substance was found to at least match or even exceed the water solubility of the test item (< 0.07 mg/L).

Due to the absence of any toxic effects in the range of water solubility, the substance is not considered to be harmful to aquatic algae.
