This study presents the results of comparative analyses carried out in the Arboretum Mlyňany, located in an uncontaminated area of south-western Slovakia. Bioaccumulation intensity of Cr, Cu, Mn, Ni, and Zn in the needles of eleven pine species was evaluated. Spectroscopic techniques along with standard protocols were applied to analyze elements content in 1- and 2-year-old needles and soil samples collected from 30 locations. The results were evaluated using Cluster Analysis and Kruskal-Wallis test. In examined stands, soil Cr, Cu, Mn, Ni, and Zn contents ranged from 14.4 to 32.6, 6.3 to 46.5, 619.4 to 2228.4, 13.2 to 37.4, and 35.2 to 62.5 mg kg⁻¹, respectively, revealing low vertical mobility. Elemental concentrations were typical for fine-textured, uncontaminated soils of Central and Eastern Europe. Total Cr, Cu, Mn, Ni, and Zn in pine needles ranged from 10.0 to 23.5, 2.6 to 7.6, 19.6 to 1804.2, 24.1 to 103.1, and 8.1 to 55.1 mg kg⁻¹, respectively, revealing slight differences between accumulation in 1- and 2-year-old needles. Pinus rigida Mill and Pinus sylvestris L. demonstrated the highest bioaccumulation capacity. The results presented in our study point to a specific bioaccumulation capacity of 11 pine species under low soil pollution levels.

这项研究提供了在斯洛伐克西南部未受污染地区的Mlyňany树木园进行的比较分析的结果。评价了11种松树针中Cr，Cu，Mn，Ni和Zn的生物积累强度。光谱技术和标准方案一起用于分析1岁和2岁针头和从30个地点收集的土壤样品中的元素含量。使用聚类分析和Kruskal-Wallis检验评估结果。在检查的林分中，土壤Cr，Cu，Mn，Ni和Zn的含量范围为14.4至32.6、6.3至46.5、619.4至2228.4、13.2至37.4和35.2至62.5 mg kg ^-1分别显示出较低的垂直迁移率。元素浓度是中欧和东欧质地细密，未污染的土壤的典型浓度。松针中的总Cr，Cu，Mn，Ni和Zn的范围分别为10.0至23.5、2.6至7.6、19.6至1804.2、24.1至103.1和8.1至55.1 mg kg ^-1，显示1中的累积量略有差异-和2岁的针头。刚性松和樟子松具有最高的生物积累能力。我们的研究结果表明，在低土壤污染水平下，11种松树具有特定的生物累积能力。
