Estrogens are known endocrine-disrupting agents which have emerged as a class of pollutants that pose danger to aquatic organisms at low concentrations. Among their negative impacts on aquatic life is their effect on reproductive behavior, which can ultimately move up trophic levels of the ecosystem resulting in a compounding environmental effect. Estrogenic compounds detected in wastewater effluents and surface water at nanogram to picogram per liter concentrations include estrone (E1), 17β-estradiol (E2), 17α-ethinylestradiol (EE2), and estriol (E3). Despite their known risks, concentrations in the Northeastern United States have remained largely unknown. We have developed and validated an SPE-GC-MS method for the quantification of these estrogenic compounds in the Whippany River and Loantaka Brook (NJ, USA). Estrogens extracted from water samples via SPE are subsequently derivatized using BSFTA + 2% TMCS and successfully separated and quantified at ppb levels using this GC-MS method.
