Distribution of estrogenic steroids in municipal wastewater treatment plants in Tehran, Iran
BACKGROUND Estrogenic steroids such as estrone (E1), 17β-estradiol (E2), estriol (E3), and 17α-ethinylestradiol (EE2) are among the most potent endocrine disrupting compounds (EDCs). Compared with North America, Europe and Japan there is no reliable information on the concentration of steroid hormones in wastewater treatment plants (WWTPs) influents and effluents in Iran. The aim of the present...
متن کاملSimultaneous Degradation of Estrone, 17β-Estradiol and 17α-Ethinyl Estradiol in an Aqueous UV/H2O2 System
UV/H₂O₂, which is an advanced treatment technology used to reduce multiple contaminants, is effective in potable water treatment. Simultaneous degradation effects and kinetics of three types of coexisting micropollutant estrogens (steroid estrogens, SEs), including estrone (E1), 17β-estradiol (E2) and 17α-ethinyl estradiol (EE2), in deionized water were studied. Experiments were carried out wit...
متن کاملComparing Methods of 17α-ethinylestradiol (EE2) Determination in Surface Water
We compared methods of determination of 17α-ethinyloestradiol (EE2) in surface water in Kielce, Poland. EE2 plays a role as a contraception agent and it is commonly used as an active agent in contraception pills. During studies three methods of EE2 determination were checked: TLC, HPLC, and ELISA assay. Samples of contaminated water were taken from eight points on four rivers crossing Kielce ci...
متن کاملOzone treatment prevents the toxicity of an environmental mixture of estrogens on rat fetal testicular development.
Effluents from wastewater treatment plants contain a mixture of estrogens (MIX: 17β-estradiol: E2, estrone: E1, estriol: E3 and 17α-ethinylestradiol EE2). High doses of estrogens have been shown to negatively impact fetal testicular development, but the impact of low doses of estrogens in mixture have yet to be elucidated. Using an organ culture system in which embryonic 15.5 day-old rat testes...
متن کاملCompetitive Degradation of Steroid Estrogens by Potassium Permanganate Combined with Ultrasound
The occurrence of natural estrogens including estrone (E1), 17β-estradiol (E2), and synthetic 17α-ethinylestradiol (EE2), which can be excreted by both humans and animals, and can enter the aqueous environment along with the discharge of domestic sewage, is a major concern since this may represent a serious health risk to humans even at extremely trace levels (ng·L(-1)). Simultaneous degradatio...
