Studies on the potential adaptation of one of the common aquatic macrophytes Elodea canadensis when immersed in a medium containing anthropogenic pollutants of various origins – metals (inorganic salts); organic salts, mineral acids; oil and its derivatives - water-soluble petrochemicals. It was found that almost all the studied pollutants do not show a clear external effect on the solid fragments of the plant (cell membranes). Thus, it was shown that Elodea canadensis is tolerant of anthropogenic pollutants that differ in nature, hazard class, physico-chemical properties, etc.
The dependence of the sensitivity of test organisms of different systematic groups and trophic levels (Escherichia coli bacteria, Chlorella vulgaris microalgae, Daphnia magna crustaceans, Lemna minor aquatic plants) to copper ions on the ratio of the volume of the medium and the number of test objects was studied. A significant decrease in EC50 indices was revealed with an increase in the volume of the test sample per one organism. The possibility of increasing the sensitivity of rapid bioassays on these organisms using the equipment and methodology developed in the Siberian Federal University is shown.
