Description of key information

The 180-min IC50 (growth inhibition) to activated sludge from a predominantly domestic source was determined to be 186 mg/L (OECD 209). A supporting study (ISO 8192 -1986) determined a 180-min EC10 (respiration inhibtion) to sewage at >10000 mg/L, however, the sludge was presumably pre-adapted (industrial source).

Key value for chemical safety assessment

EC50 for microorganisms:
186 mg/L
