Phytotoxicity of three types of organic xenobiotics (ethyl acetate, butanol-1, tetrachloromethane) was evaluated when three macrophyte species Ceratophyllum demersum , Elodea canadensis , Chara fragilis were exposed. Pollutant concentrations of 5 and 10 MAC (maximum allowable concentration) were created in microcosms. Incubation lasted for 14 days. New information was obtained experimentally that C. fragilis macrophyte is a highly sensitive test object, which can be used for bioindication purposes. Xenobiotics had no toxic effects on E. canadensis , so it can be considered for phytoremediation purposes. The data obtained are necessary for the development of phytotechnologies for water purification. A number of conditions under which these plant species can be used for ecotechnology are shown.
