Detecting Traces of 17α-Ethinylestradiol in Complex Water Matrices

Comparing Methods of 17α-ethinylestradiol (EE2) Determination in Surface Water

We compared methods of determination of 17α-ethinyloestradiol (EE2) in surface water in Kielce, Poland. EE2 plays a role as a contraception agent and it is commonly used as an active agent in contraception pills. During studies three methods of EE2 determination were checked: TLC, HPLC, and ELISA assay. Samples of contaminated water were taken from eight points on four rivers crossing Kielce ci...

Adsorption Behaviors of 17α-Ethinylestradiol in Sediment-Water System in Northern Taihu Lake, China

Adsorption behavior of 17α-ethinylestradiol (EE2) in northern Taihu Lake sediment was analyzed by using batch equilibrium experiment. Freundlich isotherm could describe the adsorption thermodynamic behavior of EE2 in sediment. Sediment organic matter (SOM) contents had important impacts on the adsorption capacity for EE2. The pH values also influenced the adsorption capacity for EE2. Increase o...

Removal of ecotoxicity of 17α-ethinylestradiol using TAML/peroxide water treatment

17α-ethinylestradiol (EE2), a synthetic oestrogen in oral contraceptives, is one of many pharmaceuticals found in inland waterways worldwide as a result of human consumption and excretion into wastewater treatment systems. At low parts per trillion (ppt), EE2 induces feminisation of male fish, diminishing reproductive success and causing fish population collapse. Intended water quality standard...

Manganese‐oxidizing bacteria mediate the degradation of 17α‐ethinylestradiol

Manganese (II) and manganese-oxidizing bacteria were used as an efficient biological system for the degradation of the xenoestrogen 17α-ethinylestradiol (EE2) at trace concentrations. Mn(2+)-derived higher oxidation states of Mn (Mn(3+), Mn(4+)) by Mn(2+)-oxidizing bacteria mediate the oxidative cleavage of the polycyclic target compound EE2. The presence of manganese (II) was found to be essen...
