Аннотация: Mercury in the modern world is a global pollutant entering the environment as a result of human activities. Currently, there are a large number of territories in the world whose soils and reservoirs contain mercury in quantities that pose a danger to human health and the environment. However, the methods that are traditionally proposed for remediation may pose a risk of secondary mercury contamination and/or negative health effects for those involved in cleaning. Phytoextraction of heavy metals from the soil environment is currently considered as one of the most promising non-invasive methods of reclamation. However, this approach has limited effectiveness for cleaning soils and reservoirs. Chemically reduced phytoextraction can increase the efficiency of this process both by converting less bioavailable mercury compounds into bioavailable fractions in the soil, and by increasing the rate of metal transfer in plants. The paper presents the results of a screening study of various chemical additives to enhance the phytoextraction of mercury with white creeping clover (Trifolium repens L.). The results obtained showed a good potential for reducing phytoextraction for the first time studied S-containing complexion, in which the monoethanolamine salt of dithiobiacetic acid was used as a sulfur-containing chelant (MEDBA).The reported study was funded by MUCTR according to the research project No. 3-2020-039.
