Duckweed as an indicator for ecological and geochemical state of the environment

Anna Baranovskaya, Natalia Baranovskaya

The article examines the level of several trace and macroelements in duckweed family (lemnaceae) on the territories of Russian Federation. We characterized the average elemental composition of duckweed in Russia. The relationship of the macrophyte chemical composition with the environment were traced. The role of aquatic plant of the duckweed family as an geo-indicator of technogenesis is considered. The distribution of mercury in macrophyte on the studied area was discovered. The high sensitivity of the biological object to the ecological and geochemical state of the environment was revealed. Also local geochemical specifics of the Tomsk region (Russia) were studied, the influence of the Northern industrial zone particularly studied there.
