Accumulation of heavy metals by edible mushrooms Eastern Kazakhstan

Abstract

The article is devoted to the study of the accumulation of heavy metals by organs of Edible Boletusedulis
mushrooms growing on the territory of Semey and outside the city. The results obtained and analyzed for the content of copper,
zinc, cadmium, and lead in edible mushrooms, and it is concluded that mushrooms growing in the city are more polluted with
heavy metals than in the country, i.e., mushrooms are sensitive bioindicators of the state of the ecological environment. Heavy
metals accumulate in them not only from the soil, but also from the air. The most important sources of environmental pollution
in East Kazakhstan are ferrous and non-ferrous metallurgy, firing of cement raw materials, fuel combustion, and automobile
emissions.
