Description of key information

Toxicity to microorganisms: EC50 = 311.82 mg/L; NOEC = 13.3 mg/L

Key value for chemical safety assessment

EC50 for microorganisms:
311.82 mg/L
EC10 or NOEC for microorganisms:
13.3 mg/L

Additional information

Toxicity to microorganisms has been investigated in an activated sludge respiration inhibition test according to OECD test methods. The substance caused a concentration related inhibition ranging from 11% at 46.7 mg/L to 98% at 2000 mg/L. The EC50 was 311.82 (257.39 - 377.75) mg/L. The EC10 was 59.4 (44.3 - 78.8) mg/L. A concentration of 13.3 mg/L caused no significantly different effects relative to untreated controls and was regarded as the NOEC.
