No inhibitory effect on the
respiration rate of activated sludge was observed at any of the
concentrations employed in the test.
Respiration rates of samples of
sludge showed a biologically significant increase (stimulation of >15%)
of 17% to 28% in mixtures at nominal test concentrations of 300 and 1000
Toxicity to microorganisms: not toxic to microorganisms: inhibition of respiration rates <15% (OECD 209, EU C.11)
EC50 for microorganisms > 1000 mg/LEC10/NOEC for microorganisms ≥ 1000 mg/LThe results indicate that the test material is not toxic to sewage bacteria up to the limits of its solubility and a NOEC and thus a PNEC cannot be determined.
