Abstract

Effect of Bis (2-butoxyethyl) adipate was studied for it’s inhibitory effect on the respiration rate of an activated sludge under in vitro conditions. The method followed in the study was that described in the OECD guideline for testing of chemicals 209 (Section-4, adopted 4th April, 1984"Activated sludge, Respiration Inhibition Test”). The EC50 (3h) of reference item3,5- dichlorophenol was determined as 24.61 mg/L. The EC50 (3h) of Bis (2- butoxyethyl) adipate was determined as 0.0841 g/L.
