Description of key information

With high probability acutely not harmful to green algae.

No effects occurred on growth of the green algae Scenedesmus subspicatus (EEC 302/87) in the range of water solubility; EC50 (72h) > 100 mg/L, NOEC (72h) >= 100mg/L (nominal)

Key value for chemical safety assessment

Additional information

The toxicity to aquatic algae was investigated according to EEC-guideline 302/87, with Scenedesmus subspicatus as test species [CIBA-GEIGY 1992]. Due to the low water solubility of the test item a solubilizer was used to prepare the stock solution. Up to the highest test concentration of 100 mg/L (nominal) no inhibition of algal growth was observed. Hence, it can be concluded that the test substance is not harmful to algae.
