The Estimation of Toxicity of Heavy Metals for Aquatic Plant Elodea Canadensis
The effect of heavy metals (Сu, Mn, Co, Ni, Zn) of physiology of submerged aquatic plant Elodea сanadensis: photosynthesis (chlorophyll epifluorescense); phototactic chloroplast displacement; plasmalemma permeability (K+ - leakage), was estimated in laboratory experiments.

| Summary: | The effect of heavy metals (Сu, Mn, Co, Ni, Zn) of physiology of submerged aquatic plant Elodea сanadensis: photosynthesis (chlorophyll epifluorescense); phototactic chloroplast displacement; plasmalemma permeability (K+ - leakage), was estimated in laboratory experiments. On the sensitivity to heavy metals the tested parameters could be ranged as follows: chlorophyll epifluorescens > phototaxis of chloroplasts > K+ - leakage from cells. According to the total inhibition for phototaxis of chloroplasts (as most integral and express parameter) the heavy metals could be ranged as follows: Mn<Ni<Co<Cu≤Zn. |
