Currently, in tern of human activity in the industrial regions, technogenic geochemical anomalies are formed. They are a source of environmental pollution by heavy metals. Phytoremediation - one of the most effective methods of cleaning of soils from heavy metals by plants which can accumulate them in their above-ground parts.. It is well known that an important role in this process is played by arbuscular mycorrhiza, which reduces the toxic effects of metals. This mechanism is based on binding of metals on the surface of the hyphae. There are a lot of conflicting data about accumulation of heavy metals by plants. The functioning of the symbiosis in heavy metals pollution is not sufficiently studied. The aim of our research was to study the peculiarities of mycorrhiza formation in plant communities on industrial dumps in terms of metal contaminants. To study of mycorrhiza in plant communities on industrial dumps, we selected roots of herbaceous plants (N = 10), which were staining with aniline blue. The results of the mycorrhiza study in industrial dumps substrate with a high content of heavy metals and low nutrient content are given in the article. It was shown, that the majority of herbaceous species in the industrial dumps has arbuscular mycorrhiza. The roots contain a small amount of hyphae. It was found that the phosphorus accumulated in the aboveground phytomass, and the metals - in plant roots.
