The inhibition of the degradation activity of activated sludge is not anticipated.
For TEA, concerning the acute toxicity to microorganisms a test
performed by Klecka et al. (1985) according to OECD TG 209 was
identified as key study. Using activated, predominantly municipal sludge
as inoculum in a static procedure an EC50 of > 1000 mg/l after 180
minutes of exposure was calculated.
For DEA, there is one Non-GLP OECD 209 guideline study available (1992).
In this short-term respiration test with domestic activated sludge the
determined EC10was >1000 mg/L (referred to nominal
