        We applied column experiments to investigate the environmental fate and transport of silver nanoparticles(AgNPs) in fully saturated conditions of porous media. These column experiments were performed to emphasize oxidation method with H2O2 concentration and acidic conditions. The mobility of AgNPs was decreased with the increasing ionic strength that the surface charge of AgNPs(zeta potential) was neutralized with the presence of positive ions of Na+. Additionally, it was also affected due to that not only more increased aggregated size of AgNPs and surface charge of quartz sand. The decreased breakthrough curves(BTCs) of bisphenol-A(BPA) and 17α-ethynylestradiol(EE2) were removed approximately 35.3 and 40%. This is due to that endocrine disrupting chemicals(EDCs) were removed with the release of OH․ radicals by the fenton-like mechanisms from acidic and fenton-like reagent presenting. This results considered that higher input AgNPs with acidic conditions is proved to realistic in-situ oxidation method. Overall, it should be emphasized that a set of column experiments employed with adjusting pH and H2O2 concentration in proved to be effective method having potential ability of in-situ degradation for removing organic contaminants such as BPA and EE2.

        In this study we present a mammalian cell culture model that allows to study the effect of endocrine disruptors (EDCs) on aromatase activity of aquatic amphibian, Bombina orientalis. Bombina orientalis aromatase gene was subcloned into a mammalian express

        환경오염이 심각해짐에 따라 국내외적으로 환경에 대한 관심이 고조되고 인체에 해를 끼치는 환경요인으로부터 방어하기 위한 많은 노력들이 기울여지고 있다. 특히 내분비계장애물질이 생식기능과 면역기능을 약화시키고, 행동 이상을 일으키며, 암 발생률을 높인다는 점이 밝혀지기 시작하면서 많은 연구들이 발표되고 여러 가지 방법들이 내분비계장애물질과 더불어 환경분야연구에 응용되어왔지만 단백질을 대상으로 연구하여 유전자기능을 연구하는 프로테오믹스(proteomics)
