Description of key information

The toxicity of the testmaterial to activated sludge of a predominantly domestic sewage under aerobicconditions was determined in a study according to 87/302/EEC, OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test), and EPA OPPTS 850.6800 (Modified Activated Sludge, Respiration Inhibition Test for Sapringly Soluble Chemicals).
No effects were seen at a concentration of 1000 mg/L after 3 hours.

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L

Additional information

The substance did not show any effects on the respiration rate of domestic sewage sludge after exposure for 3h at 21 C.

NOEC (3 h): 1000 mg/L

IC50 (3 h): > 1000 mg/L
