Os hormônios sexuais incluindo o 17a-metiltestosterona (MT) pertencem ao grupo de compostos considerados disruptores endócrinos. No entanto, poucos estudos reportam o hormônio MT em amostras ambientais. Nesse contexto, este trabalho descreve a determinação direta de MT em amostras de águas naturais baseado na electroredução, empregando o eletrodo de gota pendente de mercúrio e a voltametria de onda quadrada.

However, few studies report the presence of hormone MT in environmental samples. In this context, this paper describes the direct determination of MT in water samples based on electroredution and employing the electrode hanging mercury drop and square wave voltammetry.
