Description of key information

Depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible.

Key value for chemical safety assessment

EC50 for microorganisms:
300 mg/L
EC10 or NOEC for microorganisms:
32 mg/L

Additional information

Toxicity to microorganisms was evaluated in a GLP approach according to OECD guideline 209 using domestic non-adapted activated sludge as inoculum (BASF 2011). After an incubation period of 180 minutes the EC10 was estimated to be 32 mg/L while the EC50 was measured to be 300 mg/L.
