Description of key information

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations. No toxic effects occur at the range of solubility

Key value for chemical safety assessment

Additional information

A study was performed according to OECD guideline 209 and GLP (RCC Ltd. 2002h). Up to and including the concentration of 100 mg/L (nominal concentration), the test substance had no significant inhibitory effect (<15%) on the respiration rate of activated sludge after the incubation period of three hours. The NOEC (3h) is at least 100 mg/L and the EC50 (3h) is higher than 100 mg/L.
