Activated slugde_OECD 209: EC10(3h): 350 mg/L, EC50(3h) > 1000 mg/L, EC80(3h) > 1000 mg/L
Possible effects of the test compound on the
inhibition of oxygen consumption were determined in an activated sludge
respiration inhibition test (BASF SE, 2013). The study was performed in
accordance to OECD Guideline 209 and EU Method C.11 (2008). Activated
sludge from a municipal wastewater treatment plant served as inoculum.
Nominal test concentrations were 1000, 500, 250, 125, 62.5 mg/L as well
as a blank control. A EC10(3h) of 350 mg/L was observed. Both, EC50(3h)
and EC80(3h), were >1000 mg/L.
