Concentrations of selected heavy metals in the femora and femoral bone structure of bank (Myodes glareolus) and common (Microtus arvalis) voles from different polluted biotopes in Slovakia (Kolíňany and Nováky sites) were investigated. Length, weight, and histological structure of vole bones were also analyzed. We observed higher concentrations of lead (Pb), iron (Fe), copper (Cu), and zinc (Zn) in the bones of both species from the Kolíňany site. Significant differences were observed in the concentration of Fe in bank and common voles (p<0.05) and in the concentration of Zn (p<0.05) in common voles. The animals from Nováky had higher concentrations of cadmium (Cd) and nickel (Ni) in their bones; however, the differences were not significant. The measured values for bone length and weight were higher in both species from Nováky (p<0.05). We did not identify differences in qualitative histological characteristics of the femora between the voles (M. glareolus and M. arvalis separately) between the two biotopes. In addition, no statistically significant differences for any the measured variables of primary osteons' vascular canals were observed. Correlation analysis in M. glareolus showed a strong positive relation between Cd and Ni (r=0.52), Pb and bone weight (r=0.53), Fe and bone weight (r=0.52), and Fe and perimeter size of primary osteons' vascular canals (r=0.55). In common voles, a strong positive relation was found between Fe and Cu (r=0.60) and between Fe and perimeter size of vascular canals of primary osteons (r=0.55). Our results indicate that accumulation of some heavy metals is slightly increased in the femora of both species at Kolíňany.
研究了来自斯洛伐克不同污染生境（科利尼亚尼和诺瓦基站点）的银行（Myodes glareolus）和常见（Microtus arvalis）田鼠股骨和股骨结构中选定重金属的浓度。还分析了田鼠骨骼的长度、重量和组织学结构。我们观察到科利尼亚尼站点的两种田鼠骨骼中的铅（Pb）、铁（Fe）、铜（Cu）和锌（Zn）浓度更高。在银行和常见田鼠的 Fe 浓度（p<0.05）和常见田鼠的 Zn 浓度（p<0.05）方面观察到显著差异。来自诺瓦基的动物骨骼中的镉（Cd）和镍（Ni）浓度更高；然而，差异并不显著。两种田鼠的骨骼长度和重量的测量值在诺瓦基都更高（p<0.05）。我们没有在两个生境之间识别出股骨的定性组织学特征在田鼠（M. glareolus 和 M. arvalis 分别）之间的差异。此外，对于初级骨单位血管腔的任何测量变量都没有观察到统计学上的显著差异。在 M. glareolus 中的相关分析显示 Cd 和 Ni 之间存在强烈的正相关关系（r=0.52），Pb 和骨重之间（r=0.53），Fe 和骨重之间（r=0.52），Fe 和初级骨单位血管腔的周长之间（r=0.55）。在常见田鼠中，发现 Fe 和 Cu 之间（r=0.60）以及 Fe 和初级骨单位血管腔的周长之间（r=0.55）存在强烈的正相关关系。我们的结果表明，在科利尼亚尼的两种物种的股骨中，一些重金属的积累略有增加。
