The phytoremediation capacity of three common poplar species, white poplar ( L.), Lombardy poplar ( 'Italica'), and Euro-American hybrid poplar ( (Dode) Guinier cl. I-214), grown in a middle-sized city with a continental climate in Serbia was analyzed. For this purpose, 15 polycyclic aromatic hydrocarbons (PAHs), 10 polychlorinated biphenyls (PCBs), and 6 heavy metals (HMs) were tracked in leaves and one-year-old branches. showed the highest PAH uptake capacity, with concentrations of 821.40 ng g dry weight (DW) and 453.64 ng g DW in leaves and branches, respectively. Likewise, accumulated the highest levels of PCBs in leaves (364.53 ng g DW). Additionally, 'Italica' demonstrated the greatest accumulation potential for HMs, particularly zinc, with 310.10 µg g DW in leaves. Leaves accumulated ~30% more pollutants compared with branches. Significant differences in pollutant uptake capacities were found among species and plant organs. These findings highlight the importance of species selection in phytoremediation and clarify the role of poplar species in accumulating pollutants to mitigate urban pollution. Finally, this study provides valuable insights for future phytoremediation strategies using poplars, especially in urban environments with similar conditions.
对生长在塞尔维亚一个具有大陆性气候的中等城市的三种常见杨树品种，即银白杨（L.）、钻天杨（‘Italica’）和欧美杂交杨（（多德）吉尼耶I-214无性系）的植物修复能力进行了分析。为此，对叶片和一年生枝条中的15种多环芳烃（PAHs）、10种多氯联苯（PCBs）和6种重金属（HMs）进行了追踪。银白杨表现出最高的PAH吸收能力，叶片和枝条中的浓度分别为821.40纳克/克干重（DW）和453.64纳克/克DW。同样，银白杨叶片中PCBs的积累水平最高（364.53纳克/克DW）。此外，钻天杨对重金属，特别是锌，表现出最大的积累潜力，叶片中锌含量为310.10微克/克DW。与枝条相比，叶片积累的污染物多约30%。在物种和植物器官之间发现了污染物吸收能力的显著差异。这些发现突出了植物修复中物种选择的重要性，并阐明了杨树品种在积累污染物以减轻城市污染方面的作用。最后，本研究为未来利用杨树进行植物修复策略，特别是在具有相似条件的城市环境中，提供了有价值的见解。
