A large number of human activities result in the release of potentially toxic elements (PTEs) into the environment, which could lead to the degradation of riparian areas. This study aimed to evaluate the potential of Salix alba, Juglans regia and Populus nigra for the biomonitoring of PTEs in the riparian soils of the Sava River. Levels of seven PTEs (As, Cd, Cr, Cu, Ni, Pb and Zn) were measured in the soils, roots and leaves of plants at selected sampling sites and evaluated according to bioaccumulation and translocation factors. The obtained results showed that in riparian soils, As, Cr, Cu, Ni and Zn were at levels considered to be critical for plants. The levels of As, Cd, Cr, Ni and Zn measured in roots of Salix alba and As, Cr, Ni and Zn in its leaves were toxic for plant tissue. Toxic levels of Cr were also measured in the roots of Juglans regia and As in its leaves, as well as As and Cr in the roots of Populus nigra, and Zn in its leaves. Bioconcentration and translocation factors showed that S. alba and P. nigra have potential for the phytoextraction of Zn and Cd, while J. regia has potential for the phytoextraction of As. In terms of phytostabilization potential, S. alba proved to be good for the phytostabilization of Cd and Cu, and J. regia for the phytostabilization of Cr, As, Ni and Pb, while P. nigra showed potential for the phytostabilization of Cr, Ni, Pb and Cu.
大量人类活动导致潜在有毒元素（PTEs）释放到环境中，这可能导致河岸带地区退化。本研究旨在评估柳树、胡桃和黑杨对萨瓦河河岸带土壤中 PTEs 的生物监测潜力。在选定的采样点测量了土壤、植物根系和叶片中的七种 PTEs（As、Cd、Cr、Cu、Ni、Pb 和 Zn）水平，并根据生物积累和转运因子进行了评价。结果表明，在河岸带土壤中，As、Cr、Cu、Ni 和 Zn 的水平被认为对植物具有临界水平。柳树根系中测量的 As、Cd、Cr、Ni 和 Zn 以及叶片中的 As、Cr、Ni 和 Zn 对植物组织有毒。在胡桃的根中也测量到 Cr 的毒性水平，在其叶片中也测量到 As，在黑杨的根中也测量到 As 和 Cr，在其叶片中也测量到 Zn。生物浓缩和转运因子表明，柳树和黑杨具有提取 Zn 和 Cd 的潜力，而胡桃具有提取 As 的潜力。就植物稳定潜力而言，柳树被证明对 Cd 和 Cu 的植物稳定具有良好的效果，胡桃对 Cr、As、Ni 和 Pb 的植物稳定具有良好的效果，而黑杨对 Cr、Ni、Pb 和 Cu 的植物稳定具有良好的效果。
