The inhibition of the degradation activity of activated sludge is not
anticipated when introduced in appropriate low concentrations
For the determination of toxicity to microorganisms of
2-dimethylaminoethyl methacrylate one study is reported using Pseudomonas
putida as test organism. The result of this investigation showed a
EC10 of 42.7 mg/L. However, since the documentation for the toxicity
assessment to microorganisms of the test substance is insufficient, the
report of this study is not reliable. Hence, the assessment of the test
substance was made on the structural analogues 2-dimethylaminoethyl
acrylate (CAS# 2439-35-2). The toxicity of this substance on
microorganisms was determined in two different studies using Pseudomonas
putida (EC10 = 210 mg/L) and activated sludge from industrial sewage
treatment plant (EC20 > 1000 mg/L), respectively. The results of these
investigations showed no significant toxicity to microorganisms.
Therefore, an inhibition of the degradation activity of activated sludge
is unlikely when the test substance is introduced in appropriate low
