The studied oxbow lake is located within the borders of the city of Samara, in its Krasnoglinsky District, where in 2021–2022 field studies were conducted and samples of bottom sediments and narrow-leaved cattail biomass were collected for subsequent laboratory study. Four sample plots were established within the studied oxbow lake for the field studies; a sample plot allocated in the coastal zone of the Saratov Reservoir, in the immediate vicinity of the studied oxbow lake, served as a control. Heavy metals and metalloids were quantified in bottom sediments, rhizomes with adventitious roots, stems, and leaves of narrow-leaved cattail using inductively coupled plasma spectrometry. Seasonal and spatial differences in the accumulation of heavy metals and metalloids by narrow-leaved cattail were identified. Most elements were more actively accumulated in the rhizome with adventitious roots (Cr, V, Co, Cu, Zn, As, Pb, Cd, Rb) compared to the stems and leaves, which were dominated by Mn and Sr. Ni and Se were practically not detected by the method used in the plant organs. The obtained data indicate that the underground organs of <italic>Typha angustifolia</italic> L. are a biogeochemical barrier for the most toxic heavy metals and metalloids in technogenically polluted low-flowing freshwater reservoirs.</p> </abstract><trans-abstract xml:lang="ru"><p> </p><p>В статье представлен анализ динамики аккумуляции тяжёлых металлов (V, Cr, Mn, Co, Ni, Cu, Zn, Rb, Sr, Cd, Pb) и металлоидов (As, Se) в надземных и подземных органах рогоза узколистного (<italic>Typha angustifolia </italic>L.) в условиях слабопроточной старицы р. Сок, сформированной при создании Саратовского водохранилища. Изучаемая старица расположена в границах г. Самары, в её Красноглинском районе, где в период 2021–2022 гг. были проведены полевые исследования и отобраны образцы донных отложений и биомассы рогоза для последующего лабораторного изучения. Для полевых исследований было заложено четыре пробных площади в пределах изучаемой старицы; контролем служила пробная площадь, выделенная в прибрежной зоне Саратовского водохранилища в непосредственной близости от изучаемой старицы. Количественное определение содержания тяжёлых металлов и металлоидов в донных отложениях, корневищах с придаточными корнями, стеблях и листьях рогоза узколистного осуществляли методом спектрометрии с индуктивно-связанной плазмой. Выявлены сезонные и пространственные различия в накоплении тяжёлых металлов и металлоидов рогозом узколистным. Большинство элементов активнее аккумулировалось в корневище с придаточными корнями (Cr, V, Co, Cu, Zn, As, Pb, Cd, Rb) по сравнению со стеблями и листьями, в которых преобладали Mn, Sr. Практически не выявлялись используемым методом в растительных органах Ni и Se. Полученные данные свидетельствуют о том, что подземные органы <italic>Typha</italic><italic> </italic><italic>angustifolia</italic> L. являются биогеохимическим барьером для наиболее токсичных тяжёлых металлов и металлоидов в условиях техногенно загрязненных слабопроточных пресноводных водоёмов.</p> </trans-abstract><kwd-group xml:lang="en"><kwd>heavy metals</kwd><kwd>metalloids</kwd><kwd>translocation coefficient</kwd><kwd>macrophytes</kwd><kwd>narrow-leaved cattail</kwd><kwd>underground organs</kwd><kwd>aboveground organs</kwd><kwd>bottom sediments</kwd><kwd>oxbow</kwd><kwd>Sok River</kwd><kwd>Saratov Reservoir</kwd><kwd>Samara city</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тяжёлые металлы</kwd><kwd>металлоиды</kwd><kwd>коэффициент транслокации</kwd><kwd>макрофиты</kwd><kwd>рогоз узколистный</kwd><kwd>подземные органы</kwd><kwd>надземные органы</kwd><kwd>донные отложения</kwd><kwd>старица</kwd><kwd>река Сок</kwd><kwd>Саратовское водохранилище</kwd><kwd>город Самара</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sharma M., Kant R., Sharma A.K.
