Description Recently, increasing attention is being paid to the presence of estrogens (female sex hormones) in the environment, especially in aquatic ecosystem. Their occurrence in drinking water is also disturbing because it can have consequences to human health. Various pieces of information, not always comparable, can be found in a literature according to estrogens behaviour during drinking water treatment. Therefore, we performed technological tests on laboratory scale to assess the ability of coagulation using ferric sulphate as a coagulant, powdered activated carbon adsorption and ozonation to remove beta-estradiol and ethinylestradiol from artificially contaminated water. The analytical procedure consisting of solid-phase extraction and high-performance liquid chromatography with mass spectrometric detection was selected as a suitable tool for quantification of target compounds in water under technological tests. The removal efficiency of coagulation procedure approximately at the level of reduced values of characteristic indicators of non-specific organic matter content (CODMn, A(254), colour) -26.39 and 11.62% for beta-estradiol and ethinylestradiol, respectively, was found. On the other hand, the lowest operationally useable dosages of activated carbon or ozone led to almost complete elimination of tested compounds -99.96-99.99 and 90.27-90.92%, respectively.
