Description of key information

In a respiration inhibition test according to OECD guideline 209 a respiration inhibition of 2.0 % of activated sludge by the test item within 3 h was measured.

Key value for chemical safety assessment

Additional information

The potential toxic effect of the test item was tested according to EU method C.11, which is equal to OECD Guideline 209. Up to the highest nominal concentration of 1000 mg/L tested, the test item showed 2.0% respiration inhibition on activated sludge within 3 hours (Currenta, 2009).
