Biogeotechnological Possibilities of Carex Physodes and Kochia Prostrate (L) Sehod Plants Distributed in the Territory of Central Kyzilkum

Today, the development of science and technology has also led to the progressive development of industry. However, along with this, its negative impact onthe environment creates the prerequisites for a serious negative impact and danger on flora and fauna. Most importantly, these issues are closely linked to issues related to human health and protection. Therefore, today one of the most urgent scientific and practical problems is the search for biotechnological methods for solving the problems of ecology of technogenically destroyed soils.Our goal is to compare the old and new list of hazardous heavy metals / metalloids in the soil, to assess the degree ofdanger of a number of heavy elements in the soil by various indicators.As a result of biogenic-migration processes taking place in plant organisms, some types of toxic heavy metals have also been assimilated in the composition of soils and they have accumulated in various organs. Such properties of higher plant species can be used in phytoremediation of technogenically destroyed soils.According to the research objects,C.physodes and K.prostrata are considered plants that absorb heavy metals well. If plants assimilate heavy metals in the same amount as the soil or approximately the same, then these plants exhibit accumulative properties relative to all heavy elements in the soil.The implementation of the results of our research into practice is importantfor reducing unnecessary migration of heavy metals into the biosphere and for solving modern environmental problems
