The elemental composition of needles of forest-forming species in Baikal Siberia in areas with accumulated environmental damage

The article presents the results of studying the content of 21 chemical elements in four species of coniferous trees of forest-forming species collected on the western coast of Lake Baikal in the Irkutsk Region. The article discusses the features of the elemental composition and accumulation of heavy metals in plants growing in the foothills of Khamar-Daban, where the Baikal Pulp and Paper Mill previously operated. It has been established that plants accumulate significant amounts of the metals iron and manganese. Data obtained using X-ray fluorescence analysis can be used to monitor the state of coastal ecosystems.
