Keywords
Abstract	The biodegrability of several endocrine disruptors, namely nonylphenol (NP), nonylphenol monoethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), bisphenol A (BPA) and triclosan (TCS) was evaluated in this study, using OECD method 301F (Manometric Respirometry Test). During the test, NP, NP1EO and BPA were biodegraded to percentages equal to 61.5±6.0%, 25.9±8.1% and 87.8±6.9% as BOD, respectively. No biodegradation was observed for NP2EO under the conditions of this experiment, while results were contradictory for TCS possibly due to its toxicity on the activated sludge microorganisms. Using first order kinetics to describe tested compounds biodegradation, half-lives (t1/2) of 4.5.±0.6 and 1.3±0.1 days were calculated for NP and BPA, respectively, whereas apparent t1/2 values could not be determined for the other compounds (t1/2 > 28 days).
