摘要

本文的主要目的是利用能量色散微x射线荧光光谱(μXRF)分析方法研究植物体各部位营养物质和潜在有毒元素的含量。在马拉乔夫(斯洛伐克中部)著名矿区的废弃汞矿床Veľká Studňa上，选择了白桦(Betula pendula)和欧洲云杉(Picea abies)作为模式物种进行取样。为了研究该方法的生物积累机制和有效性，我们分别对植物体的根、茎、枝、叶/针进行了分析。在所有元素中，Ca在所有样品中含量最高。必需元素浓度下降规律如下:Ca >如果比;Mg祝辞P比;年代比;锰;潜在有毒元素的排列顺序为:Zn >菲比;阿尔比;Hg祝辞比;铜。本文评价了该分析方法在植物基质分析中的应用效率。

APPLICATION OF MICRO-X-RAY FLUORESCENCE INTO THE PLANT UPTAKE ASSESSMENT OF NUTRIENTS AND POTENTIALLY TOXIC ELEMENTS

The main aim of the article is to investigate the content of nutrients and potentially toxic elements in individual parts of the plant body using the analytical method of energy dispersive micro-X-ray fluorescence spectroscopy (μXRF). As the model species, silver birch (Betula pendula) and European spruce (Picea abies) were selected and sampled at the abandoned Hg-ore deposit Veľká Studňa on the well-known mining territory of Malachov (Central Slovakia). In order to investigate the bioaccumulation mechanism and test the efficiency of the method, the analyses were focused on the several parts of the plant body individually: roots, stems, branches, leaves/needles. Among all elements, Ca was contained in the highest concentrations in all samples. The concentrations of essential elements decreased as follows: Ca > Si > Mg > P > S > Mn; and of potentially toxic elements in order: Zn > Fe > Al > Hg > As > Cu. The article evaluates the efficiency of the presented analytical method for application in plant matrices.
