Abstract/OtherAbstract:
Data on liver and body copper, zinc, lead, and cadmium content of small mammals (rodents and insectivorous) were collected and analyzed. Data comparisons were performed in two aspects: (1) points and years of monitoring; (2) monitor species bioaccumulations. Specific bioaccumulation features were observed in some of the monitor species. A method for comparative evaluation of heavy metal loads in the different species is proposed using data for liver and body contamination. The loads of Clethrionomys glareolus and Apodemus flavicollis were compared, and the data are in agreement with data from other authors in Central Europe. A correlation between heavy metal content in the food and liver of snow vole was established. The data demonstrate that two of the regions investigated in Rila Mountain National Park could be assumed to be background locations. Some possible reasons for the heavy metal contamination of the low-altitude region in Rila are discussed. Not very significant pollution was observed around industrial facilities. Correlations between heavy metal levels in zoomonitors and meteorological factors were established.
