Abstract
Aquatic plants irrespective of whether they belong to various environmental groups in the process of their life can accumulate items in fairlyhigh concentrations. Research of the aquatic plants is a necessary component of monitoring of water bodies, as components of nature show a different response to technoge noninterference. The ability of accumulation ofchemical elements is important in assessing water quality. The purpose ofresearch was to study the sensitivity and ability of Canadian elodea (Elodeacanadensis) to the accumulation of some heavy metals (Cd2+,Cu2+, Pb2+,Zn2+) in the laboratory. Based on the results of the study, it was found thatcadmium and copper at high concentrations perniciously operates plantsE. сanadensis, compared with zinc and lead, maximum concentrations ofmetals, where there are signs of vitality of plants: lead-10 MPC, copper-5MPC, zinc-10 MPC, for cadmium-5 MPC. On the level of accumulation inplants of E.сanadensis of heavy metals can be positioned in the followingseries: Cu >Zn >Pb>Cd. The possibility of using plants E. сanadensispurification from heavy metals.Key words: higher aquatic vegetation, heavy metals, Elodea canadensis, LPC.
