Description of key information

EC50 (3h) > 1000 mg/l (nominal), based on main test and pre-test.

NOEC (3h) = aprrox. 10 mg/l (nominal), based on pre-test.

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L
EC10 or NOEC for microorganisms:
10 mg/L

Additional information

The effects of the substance on micro-organisms from activated sludge were evaluated by measuring their respiration rate in a pretest and a main test (verification experiment) in the presence of different concentrations of the test substance, according to the OECD Guideline 209 and EU Method C.11. The respiration rates of the control, reference and test item were measured after a contact time of 3 hours. The inhibitory effects of the test and the reference substance were determined in comparison to the control respiration rates.

EC50 (3h) > 1000 mg/l (nominal), based on main test and pre test.

NOEC (3h) = aprrox. 10 mg/l (nominal), based on pre-test.
