The toxicity of tributyl acetylcitrate towards activated sludge was
investigated in a study conducted according to EU Method C.11
(Biodegradation: Activated Sludge Respiration Inhibition Test; 2008) and
OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test;
1984). Based on the results of a screening test, the definitive test was
performed as a limit test using three parallels with the highest nominal
concentration of ca. 1000 mg/L. A fourth flask containing test substance
(1006 mg/L), tap water and synthetic sewage feed was used for testing
autoxidation of the test substance. At the concentration tested no
inhibitory effects were observed (3 h EC10>1000 mg/L nominal).
