The elemental, fatty acid composition and content of polyphenols in the Pinus sylvestris L pollen, growing within the territory of Ulan-Ude and the Republic of Buryatia background territories, were determined. It is shown that with technogenic pollution in pollen, the content of iron, nickel, lead, cadmium and mercury increases, and the content of manganese decreases. In the fatty acid composition under stress conditions, an increase in the content of unsaturated fatty acids, and in particular, trans- and cis-forms of oleic acid, is observed. A decrease in the content of polyphenolic compounds in samples from contaminated areas was noted. Thus, the chemical composition of pine pollen can be used as an indicator of anthropogenic (technogenic) impact and early diagnosis of the stress state of the forest during forest pathological monitoring.
