Abstract
Based on long-term research (1993-2022), the content of chemical elements (Na, K, Ca, Cu, Zn, Fe, Pb, Sr, Zr, Cd, Ni, Co, Cr, Ba, Cd, and Mn) has been determined in 17 plant species of the northern West Siberia region. The regional geochemical background of dominant plant species has been established, and an assessment of changes in the chemical composition of plants in the area of oil and gas condensate field development in the northern West Siberia region has been provided. Indicator species reflecting early trends in ecosystem transformation under the influence of anthropogenic load and associations of chemical elements linked to various sources of pollution have been recommended. The role of phytoindication methods has been demonstrated in detecting subtle changes in the environmental state in the conditions of gas condensate field sites.
