Abstract:

The development of the chemical and pharmaceutical industry and the massive use of synthetic substances in various industries has become indispensable for our society. Unfortunately, this progress has brought a whole new kind of pollution. It is a group of substances which imagine for living organisms’ greater risk than 'normal' organic pollution. Because they have extraneous origin compared with naturally occurring compounds, they are called "Xenobiotics." It is a group comprising a large number of different substances, with dissimilar physical, chemical and biological properties such as pharmaceuticals, pesticides, detergents, paints, varnishes, plastic packaging, food additives, cosmetic products, drugs, and many others. Although these substances began to enter the water cycle as early as 30 years of the 20th century, their concentration often moves to the limit of the detection limit, so their presence in the water began to be examined in more detail in the 1980s, following the development of analytical technologies chemical composition of water. The main danger of these substances is that doesn’t primarily effect on water quality, but directly affect on the organisms  by confusing of the endocrine system or by directly damaging RNA or DNA, causing mutagenic changes, cancer-causing proliferation, birth defects, metabolic disorders, gender changes, the degeneration of reproductive capacity of entire populations or the disappearance of self-preservation instinct. The source of xenobiotics in the water cycle is predominantly wastewater, which generated through the wastewater treatment, which not designed to eliminate this type of pollution.
he dissertation thesis deals with the issue of xenobiotics in wastewater and is divided into the theoretical and experimental part. The theoretical part summarizes the xenobiotics current state of knowledge in wastewater from their history, origin, classification, possibilities of elimination to impacts on the environ
