The subject of this research is mercury pollution in the alpine zone of the High Tatra Mountains (the West Carpathians). The snow vole (Chionomys nivalis) was chosen as a bioindicator. Mercury concentrations in the tail tips from captured individuals were examined. The samples were collected over the span of 2 years, from May 2016 to November 2017. The smaller (1-year-old) individuals had higher mercury concentrations in their tails than the bigger (2-year-old) individuals, suggesting recent aerial contamination of alpine habitats. The amount of mercury found in the tails did not differ between sexes. The differences in mercury concentration between animals caught in the spring and autumn were also insignificant. The possible relationship between mercury in the tissues and the seasonal variability of the water cycle in the mountains (snow melting, precipitation) is discussed. [ABSTRACT FROM AUTHOR] |
