Further investigation of risk elements content in the bones of wild rodents from a polluted area in Slovakia.

Martiniakova M, Omelka R, Grosskopf B, Duranova H, Stawarz R, Balaz I - Acta Vet. Scand. (2015)

Bottom Line: Significant differences were observed for the content of Fe between A. flavicollis and M. glareolus (P < 0.05).Moreover, the concentrations of Cu, Zn and Ni were significantly higher in the bones of all three species (P < 0.05) in comparison with the values obtained in the same animal species at the same site in February 2007.Our results demonstrate an increased accumulation of Cu, Zn and Ni in the femora of M. glareolus, A. flavicollis and A. sylvaticus from the Kolíňany area and thus indicate towards ongoing contamination of this locality.

ABSTRACT

Background: Wild rodents are suitable for monitoring environmental pollution and exposure risk assessment for people living in contaminated areas. The content of selected risk elements in the femora of bank vole (Myodes glareolus), yellow-necked mouse (Apodemus flavicollis) and wood mouse (Apodemus sylvaticus) was estimated from the Kolíňany area of Slovakia, which is characterized by a high degree of environmental pollution. The rodents were trapped in February 2011 using standard theriological methods. All animals (n = 32) were adult males in good physical condition. The concentrations of Fe, Cu, Zn and Ni in their bones were determined by atomic absorption spectrophotometry.

Results: The highest concentrations of Fe and Cu were detected in the bones of yellow-necked mouse. Significant differences were observed for the content of Fe between A. flavicollis and M. glareolus (P < 0.05). The highest levels of Zn and Ni were found in the femora of wood mouse; however, significant differences were not detected between the rodents. Moreover, the concentrations of Cu, Zn and Ni were significantly higher in the bones of all three species (P < 0.05) in comparison with the values obtained in the same animal species at the same site in February 2007.

Conclusions: Our results demonstrate an increased accumulation of Cu, Zn and Ni in the femora of M. glareolus, A. flavicollis and A. sylvaticus from the Kolíňany area and thus indicate towards ongoing contamination of this locality.

Mentions: The individuals of bank vole (M. glareolus, n = 14), yellow-necked mouse (A. flavicollis, n = 6) and wood mouse (A. sylvaticus, n = 12) were obtained by means of the standard theriological methods and procedures from wood ecosystems [20] in February 2011. The wild rodents were trapped near the water pond in Kolíňany (Nitra district, Slovakia; Fig. 1) which is located ~10 km away from the town Nitra and it is considered to be a heavily polluted region [18, 19]. Possible sources of pollution for this district are small factories, the application of agricultural chemicals, traffic pollution and the waste from large local industrial complexes. All animals caught were adult males (aged 4–5 months of age as determined by dental wear). They appeared to be in good physical condition and without gross lesions at necropsy. All procedures were approved by the Ministry of Environment of the Slovak Republic.Fig. 1
