Research on Photolysis of Steroid Estrogens in Aquatic System

Abstract:

Estrogens such as estrone (E1), 17β-estradiol (E2) and estriol (E3) which are excreted by humans and animals or synthetic compounds such as 17α-ethinylestradiol (EE2) are a group of biologically active compounds that are synthesized from cholesterol and have a steroid ring in common. Steroid estrogens harm to organisms at very low concentrations with much more endocrine function than other EDCs. Obviously, it is an important issue to explore their degradation mechanisms and effective methods. In the present studies, 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) were used as target compounds, and the photodegradation of them were investigated in aqueous solution using natural sunlight produced using a xenon lamp, or ultraviolet light via a Hg lamp.
