Abstract: 
NEW IDEAS are presented: A fundamental concept is proposed of aquatic ecosystem as a bioreactor that carries out the function of water purification in natural water bodies and streams. According to the new conceptualization that was suggested by the auhtor, an ecosystem as a bioreactor has the following characteristic attributes: (1) it is a large-scale (large-volume) bioreactor; (2) it is a diversified (in terms of the number of taxa and the scope of functional activities) bioreactor; (3) it possesses a broad range of biocatalytic (chemical-transforming and degrading) capabilities. 
NEW FACTS were obtained in the experiments of the author: New experimental data on xenobiotics-induced inhibition of the functional activity of the molluscs Unio tumidus, U. pictorum, M. galloprovincialis and Limnaea (Lymnaea) stagnalis demonstrated a new type of the environmental hazard from sublethal concentrations of pollutants (exemplified by synthetic surfactants and detergents).
