Selection of suitable bioindicators for the determination of xenobiotics residuals

Bio-indicators are organisms, which we can use to evaluate contamination of terestrial and aquatic ecosystems by xenobiotics. This thesis deals above all with bio-indicators of vegetal and animal origin, which are capable to identify and quantify persistent organic pollutants and its residual contamination. This xenobiotics comes from human activities, most by consumer and automotive industry, inconsiderate agriculture. Thanks to its unpremeditated application and waste disposal, which are contaminated with them, ecosystems are infested and persistent organic pollutant‘s residuals are persisting for decades. By the help of bio-indicators we can find the source of contamination and size up its seriousness, we can observe its development and biological effect on organisms, which live in contaminated areas. In this thesis attention is given especially to polychlorinated bifenyls (PCB), polyaromatic hydrocarbons (PAH), organochlorinated pesticides (OPC). polybrominated difenylethers (PBDE) and PCCDs/Fs, its influence on the health and its distribution in our surroundings, especially in waste dumps and forgotten pollutants sources
