Voltammetric Determination of the Total Content of the Most Commonly Occurring Estrogens in Water Media.

ABSTRACT: Estrogens in aquatic environments pose significant ecological and health risks due to their cumulative effects rather than individual impacts. This study investigates the voltammetric behavior of estrone (E1), 17β-estradiol (E2), estriol (E3), and 17α-ethinylestradiol (EE2), presenting a cost-effective and straightforward method for their simultaneous determination. Using differential pulse voltammetry (DPV) with a boron-doped diamond electrode, the method demonstrates high precision (deviations under 4%) and a linear dynamic range of 15.35-134.55 µmol·L^-1. Integration of a vacuum evaporation step reduced detection limits to 10^-8 mol·L^-1, enabling effective analysis of real water samples. This optimized approach ensures practical applicability for monitorin
