Abstract: The seasonal aspects of biomass dynamics and heavy metals accumulation in biomass were investigated for 27 species of high aquatic plants of shallow water reservoirs of North-West of Russia with different level of sediments pollution with heavy metals. It is shown that the character of seasonal dynamics of biomass and heavy metals accumulation differs at species, belonging to different ecological groups. The maximal accumulation of biomass and heavy metals at helophytes and submersed species is observed at the end of vegetation season, but for aquatic plants with floating leaves it is typical in the middle of vegetation. In polluted shallow water bodies, all groups demonstrate more fast accumulating of heavy metals and more shot period of active biomass accumulation.
