Description of key information

After 3 hours of exposure the substance showed 87.3 % respiration inhibition of activated sludge at a test concentration of 10000 mg/L. The EC50 is 4539 mg/L (by probit analysis) and the effect value is related to nominal concentration, since no analytical monitoring was performed (Kanne, 1989).

Key value for chemical safety assessment

EC50 for microorganisms:
