Проведен отбор проб субстратов (почвы, донные отложения). Методом масс-спектрометрии с индуктивно связанной плазмой определено содержание редкоземельных элементов (РЗЭ) в отобранных образцах. Установлено повышенное содержание РЗЭ в растениях в сравнении с фоновыми значениями, рассчитаны коэффициенты биоаккумуляции. Рекомендовано применение полученных результатов при разработке фитотехнологий для снижения негативного воздействия от закрытого редкометалльного предприятия.</p></abstract><trans-abstract xml:lang="en"><p>Terrestrial and aquatic plants commonly found in the vicinity of the “Umbozero” rare-metal ore mine (Murmansk Region) were sampled for the first time and investigated. The studied species include goat willow, downy birch, subarctic milkvetch, narrowleaf bur-reed, and shield fern. Substrate samples (soil and bottom sediments) were also collected. Using inductively coupled plasma mass spectrometry (ICP-MS), the concentrations of rare-earth elements (REEs) in all collected samples were determined. Elevated REE contents were identified in plant samples compared to background levels, and bioaccumulation coefficients were calculated. The obtained results are recommended for use in the development of phytotechnologies aimed at reducing the negative environmental impact of the decommissioned rare-metal mining facility.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>редкоземельные элементы</kwd><kwd>хвостохранилища</kwd><kwd>коэффициент биоаккумуляции</kwd><kwd>Astragalus subpolaris</kwd><kwd>Salix spp.</kwd><kwd>Betula pubescens Ehrh</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rare-earth elements</kwd><kwd>tailings</kwd><kwd>bioaccumulation coefficient</kwd><kwd>Astragalus subpolaris</kwd><kwd>Salix spp.</kwd><kwd>Betula pubescens Ehrh</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают признательность Красавцеву С.Э. за помощь в отборе проб.
