Description of key information

After three hours the test material showed 11.11 % respiration inhibition of activated sludge at the highest concentration of 1000 mg/L. An EC-50 value of higher than 1000 mg/l and  EC-10 value of 856.5 mg/l was determined (by probit analysis) (Richter, 2012). 

Key value for chemical safety assessment

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

Additional information

EC50 should read > 1000 mg/l
