Background Concentrations of Chemical Elements in Plants Inhabiting the Northern Part of Western Siberia and Changes They Undergo under the Impact of Oil and Gas Production
Abstract
Concentrations of chemical elements (Na, K, Ca, Cu, Zn, Fe, Pb, Sr, Zr, Cd, Ni, Co, Cr, Ba, Cd, and Mn) in 17 plant species inhabiting the northern part of Western Siberia have been determined on the basis of data collected in the course of long-term (1993–2022) studies. The regional geochemical background of predominant plant species is determined, and changes in the chemical composition of plants in the vicinity of oil and gas condensate fields in the northern part of Western Siberia are analyzed. Indicator species reflecting early trends in ecosystem transformations under the impact of anthropogenic pressure and associations of chemical elements typical for various pollution sources are proposed. It is demonstrated that phytoindication can be used to detect subtle environmental changes in the vicinity of gas condensate fields.
期刊介绍：
Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
