Additional information

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).
