Abstract
The article provides data on the content of some chemical elements (Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pb) in edible mushrooms growing in the Transbaikal Territory. To determine microelements in the studied objects, the method of X-ray fluorescence analysis was used. The maximum accumulation of zinc, iron, manganese and the minimum accumulation of cobalt and lead were found in all studied species of mushrooms. In general, the average content of chemical elements in the studied types of mushrooms is – iron > zinc > copper > manganese > titanium > nickel ≈ cobalt > lead. Zinc accumulation occurred most intensively in the fruiting bodies of Suillus luteus, Lactarius deliciosus, Boletus edulis and Leccinum aurantiacum. Exceeding the maximum permissible concentration for nickel, copper, zinc and lead (in terms of wet weight) was not detected. Based on the total content of chemical elements, the following series can be constructed: Suillus variegatus > Lactarius trivialis > Lactarius deliciosus ≈ Suillus luteus > Boletus edulis > Leccinum aurantiacum. Suillus variegatus accumulates most of the studied elements in maximum quantities. It was revealed that Lactarius trivialis, Lactarius trivialis, Boletus edulis and Leccinum aurantiacum concentrate metals mainly in the caps. The content of the studied elements in mushrooms of the Transbaikal Territory is lower compared to their accumulation in mushrooms of other territories of Russia. All types of mushrooms accumulate zinc in high concentrations. For zinc and copper, the concentration coefficient turned out to be greater than unity, which indicates intensive accumulation of elements in the fruiting bodies of fungi. Leccinum aurantiacum is characterized by the lowest ability to accumulate chemical elements, which may be due to the developed barrier mechanisms of the species. This species has a high affinity for copper
