Simultaneous determination of endocrine disrupter compounds
(EDCs), namely diltiazem, progesterone, benzylbutylphthalate (BBP), estrone, and carbamazepine
(Cbz) were performed by using high performance LC-electrospray tandem MS. The ultrasound-aided
sequential extraction of sludge samples was optimized to increase extraction efficiencies of the
analytes; ranging between 93.0-98.3% recovery. The limit of detection values for diltiazem,
progesterone, BBP, estrone, and Cbz were found as 0.78, 0.72, 0.24, 0.75, and 0.72 mu g/kg,
respectively. Sludge samples taken from Ankara Tatlar; Hurma, Lara and Kemer of Antalya, and
Middle East Technical University-vacuum rotating membrane wastewater treatment plant (WWTP)
aeration tanks were analyzed for their EDCs contents under optimized conditions. Diltiazem was
found in all the samples in the range between 116.4-180.8 ng/g while progesterone and estrone
were not detected in any of the samples analyzed with the exception of Tatlar WWTP. The BBP
concentration was between beyond detection and 9195.5 ng/g. In addition, Cbz was found in all the
samples ranging from 25.6 to 118.8 ng/g.
