Zusammenfassung
To remove efficiently steroid hormones will soon and quickly become a key water quality issue in densely populated and water deficient areas. Prague city (Czech Republic) with 1.2 million inhabitants and a well defined drainage and sewage system is an ideal place to study input and fate of natural and synthetic estrogens in surface water. Concentrations of 17β-estradiol, estriol, estrone, 17α- ethinylestradiol, mestranol and norethisterone have been determined in the creeks and rivers, in the city´s sewage treatment plants and in the water works of Prague. The highest total estrogen content of 466 ng/l is found in the sewage entering the major sewage treatment plant. The effluents still contain between 72 and 100 ng/l total estrogens. Before entering the city of Prague, the water of the river Vltava has a total estrogen content below 1 ng/l. It increases up to 3.8 ng/l in the city. During wastewater treatment the natural estrogen 17β-estradiol is degraded to estrone. Presence of 17α-ethinylestradiol in small creeks all over the city area suggests environmental persistence and general input.
