Xenobiotic substances in solid matrices of aquatic ecosystems

Monitoring of substances such as halogenated and other hazardous organic pollutants or heavy metals provides valuable information about environmental pollution. These persistent substances accumulate in both biotic and abiotic compartments, as well as in food chains, and many of them act as human carcinogens and endocrine disruptors. The Czech Hydrometeorological Institute’s annual monitoring results show long-term contamination of surface water ecosystem in the Czech Republic by these substances.
