EC10 > 1000 mg/L (OECD 209, activated sludge)

Key value for chemical safety assessment

Additional information

One study is available on the toxicity of the test substance to activated sludge. The study was conducted according to OECD guideline 209 and GLP (Feil, 2011). The activated sludge was exposed to nominal test concentrations of 10, 32, 100, 320 and 1000 mg/L, during 3 hours. In comparison to the inoculum controls the respiration rate of the activated sludge was not inhibited at the test concentrations up to 320 mg/L. The EC10 and EC50 were determined to be > 1000 mg/L.
