Abstract

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.
