The article is focused on the application of Energy dispersive micro X-ray fluorescence spectroscopy as a specific method to determine the contents of potentially toxic elements and its spread in plant tissues. As a model species, Quercus spp. were selected. In order to compare the obtained results with previous research, four well-described abandoned Cu-deposits were selected for sampling: Ľubietová (Slovakia), Libiola and Caporciano (Italy), and São Domingos (Portugal). The results of micro X-ray fluorescence spectrometry confirm the irregular contamination of Quercus spp. by potentially toxic elements. The level of contamination is the highest predominantly in the root cortex, where is also the highest Ca contents (with exception of São Domingos). At Ľubietová and Caporciano, high Ni content was described in branches cortex, in branches mesoderm also Fe, Cu and Zn. At the same time, the inhibition influence of Ca was also confirmed regarding the input of these elements into plants.

文章重点介绍了应用能量色散显微X射线荧光光谱作为确定潜在有毒元素含量及其在植物组织中扩散的具体方法。作为模式种，Quercus spp。被选中。为了将获得的结果与之前的研究进行比较，选择了四个描述良好的废弃铜矿床进行采样：Ľubietová（斯洛伐克）、Libiola 和 Caporciano（意大利）以及 São Domingos（葡萄牙）。显微X射线荧光光谱结果证实栎属不规则污染属 通过潜在的有毒元素。污染程度最高的主要是根皮层，那里的钙含量也最高（圣多明各除外）。在 Ľubietová 和 Caporciano，在树枝皮层、树枝中胚层以及 Fe、Cu 和 Zn 中描述了高镍含量。同时，也证实了Ca对这些元素输入植物的抑制作用。
