Description of key information

Additional information

A one-page summary on results of an OECD 203 guideline study with zebrafish is available (Ciba-Geigy, Dyestuffs and Chemicals Division 1990). A limit test with a concentration of 1000 mg/L was performed. No mortality was observed after 48 and 96 h.

Additionally, results of an OECD 209 guidline study are available (Ciba-Geigy, Dyestuffs and Chemicals Division 1990). The Respiration Inhibition Test resulted in an IC50-value after 3 h of above 100 mg/L.

Therefore, the test item is regarded with high probability acutely not harmful to aquatic organisms. The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate concentrations.
