Abstract
The relevance of this work is related to solving the problem of soil pollution with heavy metals by applying Fallopia Sachalinensis and obtaining benefits in the recovery process. The aim of the work is to develop an algorithm for geoecological assessment of phytoremediation features when using plants, taking into account the conditions of anthropogenic soil pollution with heavy metals, as well as physiological characteristics and species-specific reactions under abiotic and biotic stress. For the quantitative determination of flavonoids in Fallopia Sachalinensis, a spectrophotometric method was used in the work on a Shimadzu – UV 1800 instrument using a complexing additive – 5% aluminum chloride solution, to determine the content of tannins, the redox titration method was used, in order to detect amino acids, qualitative reactions were carried out with aqueous extraction for three copies of each sample. Quantitative determination of amino acids in the studied samples is carried out on the AAA-339 amino acid analyzer (Czechoslovakia). Approbation of the algorithm on Fallopia Sachalinensis under conditions of anthropogenic contamination of soils of the Bashkir Trans-Urals with heavy metals showed that the plant has an indicator potential, but excludes the production of natural biologically active substances from biomass. At the same time, Fallopia Sachalinensis is resistant to soil pollution with heavy metals and has an increased resistance to industrial pollution, and the possibility of using it as an indicator of soil pollution has also been determined
