“…Based on the research of Vorobieva et al (2020), it was decided to use water closer to its natural composition for the experiment, rather than undertake the creation of artificial water using artificial media. At the same time, since a considerable amount of water was needed for the experiment, and it was not possible to transport such a large amount of water from the field, it was decided to use aquarium water for the study, the composition of which much more closely reflects natural environmental conditions (Table 1).…”

A laboratory experiment was performed to find out the potential bioaccumulation of metals (Al, Cu, Cd, Ni, Pb, Fe, Mn) in aquatic plants acting as natural biosorbents in the environment depending on the variation of water pH. Two plants were selected for the study: branched bur-reed—Sparganium erectum L., as a representative of emergent plants; and river water-crowfoot—Ranunculus fluitans Wimm., 1841, as a representative of submergent plants. The bioaccumulation of metals in plants relative to water (BCFW) was determined, and the metal pollution index (MPI) was calculated. The metal content in water and plants before the experiment was arranged in the following series of increasing values: Cd = Ni < Cu < Pb < Mn < Al < Fe (water) and Cd < Cu < Ni < Pb < Al < Fe < Mn (in both plants). The lowest concentration of cadmium was found in water both at the end and beginning of the experiment. In turn, aluminum level increased, and its concentration was the highest in both acidic and alkaline water. This suggests that aluminum is definitely more available to the organisms living in it under such conditions, and in higher concentrations may be a limiting factor for them. Bioaccumulation of metals (BCFW) in neutral and alkaline environments was higher in branched bur-reed, and in acidic conditions in river water-crowfoot. This may provide a basis for using specific plant species to selectively accumulate metals depending on the range of water pH. This is also supported by the MPI values, which indicate that they have a very high and often the highest impact on metal pollution levels. The observed variability of metals bioaccumulation against the condition of hydromacrophytes makes it possible to consider these plants as biosorbents used in constructed biological treatment plants, which, depending on the species placed there, can selectively absorb particular trace elements. The plants used in the experiment are common hydromacrophytes of Europe, so they can be used in the construction of artificial wetlands across the continent. The apparent diversity of metal accumulation in relation to hydromacrophytes indicates that this type of site can be inhabited by specific species, which can significantly improve the purification of natural or anthropogenic water reservoirs, i.e., those that are intended to perform a filtering function.

The paper presents a comparative study of the toxicity of chromium and molybdenum, carried out in hard aquarium 0,14⁰Clark and soft natural 8,2⁰Clark waters. A decrease in water hardness leads to an increase in the acute toxicity of metals, which is expressed in a decrease in the values of semi-lethal concentrations by 3 times for molybdenum and 25 times for chromium.The results obtained show that the toxicity of metals can differ significantly in waters with different hydrochemical compositions. The data presented in the work can be used in the development of regional MPC standards.
