Popis: In order to achieve sustainable development, environmental protection shall constitute an integral part of the development process and cannot be considered in isolation from it [1]. The environment, especially water ecosystem, is continuously loaded with foreign organic chemicals (xenobiotics) released by urban communities and industries. Water is not a com‐ mercial product like any other but, rather, a heritage which must be protected, defended and treated as such [2]. In the 20th century, many organic compounds, such as polychlorinat‐ ed biphenyls (PCBs), organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) have been produced and, in part, released into the environment [3]. The ultimate sink for many of these contaminants is the aquatic environment, either due to direct discharges or to hydro‐ logic and atmospheric processes [4]. In the 21st century „new“ pollutants namely pharma‐ ceuticals, cosmetics and endocrine disrupting chemicals (EDCs) have become a source of concern. Collectively, they are referred to as PPCPs (Pharmaceuticals and Personal Care Products) and are now viewed as emerging contaminants. A wide range of pharmaceutical and personal care products (PPCPs) is available on the market. From this range various classes, e.g., antibiotics, antiphlogistics, antiepileptics, beta-blockers, lipid regulators, vaso‐ dilators, and sympathomimetics, have been detected in drinking water, groundwater, wastewater, sewage, and manure [5]. In last time there is increasing evidence that some of these compounds are persistent in the environment, impacting nontarget organisms in vari‐ ous ways including changes in sex ratios of higher organisms [6,7]. The presence of a xeno‐
