The authors discovered the phytoremediation potential of previously unstudied species of aquatic macrophytes, namely, Ludwigia repens JR Forst., Micranthemum micranthemoides (Nutt.) Wettst., аnd Micranthemum umbrosum (JF Gmel.) SF Blake. The plants were exposed to a mixture of heavy metals (Pb, Zn, Cu, Cd). Experiments of the authors showed that in the presence of the aquatic plants, an accelerated decrease in the concentrations of all four metals as compared to control (water systems without plants) took place. The authors found phytotoxicity of the studied mixture of the heavy metals to macrophytes Micranthemum micranthemoides, and M. umbrosum.
