Detection of Estrogens from Aquatic Environments
by Gas Chromatographic Method

Abstract:

The presence of estrogens in the environment and their effects especially on reproductive health on aquatic animals and on humans has become a subject of growing concern worldwide. This paper describes the preliminary data and tests performed in order to obtain and optimize a new gas chromatographic method for the identification of the most common found estrogen in the environment, 17a-ethinylestradiol. For this purpose, a gas chromatograph equipped with an electron capture detector and a chromatographic column DB-5MS has been used and the specific parameters have been optimized. The developed analytical method was then tested on two types of water (waste water and surface water). The processing of samples followed several steps, involving liquid-liquid extraction, concentration, purification and derivatization. The linearity range of the method has been established between 0.025 - 0.100 mg/L. The recovery for 17á-ethinylestradiol fortified water samples reached 85.30 %. Keywords: aquatic environment, estrogens, GC-ECD method
