Studying of Heavy Metals (Copper and Cadmium) Interactions with Biomass of the Bryophyte-cyanobacteria Community

Using the method of atomic absorption spectrometry (AAS), the concentrations of some elements (Cu, Cd, Fe, Mn, Pb, Ni, and As ) were measured in the biomass of a bryophyte OST-1 with cyanobacteria (Phormidium sp., Oscillatoria sp.) community after its incubation in aquatic medium with added Cu (4 mg/L) and Cd (0,01 mg/L). Fe, Mn, Pb, Ni, and As were not added to the aquatic medium. It was found that after the incubation the concentrations of Cu and Cd increased. The concentrations of Fe, Mn, Pb, Ni, and As in the biomass did not change in the course of the incubation of the biomass. The results contribute to the scientific basis for developing phytoremediation.
