Accumulation of heavy metals and morphophysiological responses of two common species of submerged hydrophytes (Elodea canadensis Michx. and Potamogeton perfoliatus L.) from habitats with differen levels of pollutions were studied. The investigations were carried out in the surroundings of the metallurgical plant, the town of Revda, Sverdlovsk oblast, Russia (upstream and downstream Revda River). It was shown that hydrophytes from polluted habitats (downstream) differed from plants of a less polluted site (upstream) by the higher accumulation of HMs, the greater thickness of a leaf, the larger cells and chloroplasts. Plants in the polluted site were characterized by a high photosynthetic pigments, while flavonoid content in the leaves was lower. The identified trends indicate a high adaptive potential of these plant species and their ability to inhabit the environment polluted with metals and other pollutants.
