Abstract：
The study was carried out in the most industrialised region of southern Poland. Four areas were selected for the study: the vicinity of the Miasteczko Śląskie Zn-Pb-works (ZW; with three transects selected: A, B, and C), and the metalliferous waste heaps (H1, H2, H3). Samples were taken from the surface soil layer, while only mature silver birch (Betula pendula Roth) trees (3-4 m high) growing spontaneously in the study area were selected for the collection of leaves. The analysis of metals including trace metals (TMs; Ag, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Ni, Pb, Tl, and Zn) in the soil and leaves, as well as the contents of specialized leaf compounds belonging to polyphenols were performed. In general, the B. pendula trees in transects A and B located within 500 m of the furnaces exhibited 3-9 times higher content of TMs in their leaves compared to the plants located further away from the Zn smelter. In contrast, the quantity of TM in trees from transect C was independent of distance. The accumulation of TMs in the leaves was significantly lower in the metalliferous waste heap sites compared to the ZW area. It was hypothesised that the accumulation of TMs in B. pendula leaves would depend on the location and distance from the polluting source. It was demonstrated that TMs content in soil affects the accumulation of phenolic acids and flavonoids.
摘要：
这项研究是在波兰南部工业化程度最高的地区进行的。选择了四个区域进行研究：MiasteczkolstonskieZn-Pb-works附近（ZW；选择了三个样带：A，B,andC),和含金属废物堆(H1、H2、H3)。样品取自表层土壤层，而仅选择在研究区域自发生长的成熟的白桦树（BetulapendulaRoth）树（高3-4m）来收集叶子。金属分析，包括痕量金属(TM；Ag，Ca,Cd,Cr,Cu,Fe,K,Mg,MnNi,Pb,Tl,和锌)在土壤和树叶中，以及属于多酚的特殊叶化合物的含量。总的来说,与远离Zn冶炼厂的植物相比，位于熔炉500m内的A和B样带中的B.pendula树的叶子中的TM含量高3-9倍。相比之下,来自横断面C的树木中TM的数量与距离无关。与ZW地区相比，含金属废物堆放地点的叶片中TM的积累明显较低。假设B.pendula叶片中TM的积累将取决于距污染源的位置和距离。结果表明，土壤中的TM含量会影响酚酸和类黄酮的积累。
