Description of key information
The inhibition of the degradation activity of activated sludge is not anticipated when introduced to biological treatment plants in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
The toxicity of the test compound to the degradation activity of activated sludge was assessed in a GLP study conducted according to OECD guideline 209. The activated sludge was collected at a municipal wastewater treatment plant and exposed for 3h to the following test item concentrations: 62.5, 125, 250, 500, and 1000 mg/L. No effect on the respiration rate coulde be observed in any of the concentration and the EC10 was determined to be > 1000 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
