|Title: MEASUREMENT OF THE ATMOSPHERE LOADING OF THE SLOVAK CARPATHIANS USING BRYOPHYTE TECHNIQUE|
|Author: BLANKA MANKOVSKA, JULIUS OSZLANYI, PETER BARANCOK|
|Abstract: Biomonitoring of multielement atmospheric deposition using terrestrial moss is a well-established
technique in Europe. The moss samples of Hylocomium splendens, Pleurozium schreberi and Dicranum sp. were collected in the Slovak part of the Carpathian Mountains (sites of Geldek,
Štefanová, Poľana, Východná, Stolíky, Morské oko). A total of 39 elements including a number of toxic metals and rare earths were determined by instrumental neutron activation analysis using epithermal neutrons at the IBR-2 reactor of FLNP JINR. In addition to NAA, atomic absorption
spectrometry was applied to determine the content of Cd, Cu, Hg and Pb and elemental analyzer to determine the content of N and S. In comparison to the median northern Norway values of
heavy metal contents in moss the Slovak atmospheric deposition loads of the elements were found to be higher than average. We found maximal concentrations of As (45 times), Cd (110 times), Cu (64 times), Fe (44 times), Hg (174 times), Pb (105 times) and Zn (14 times) in site Stolíky; Cr (218 times) and Mn (7 times) in site Morské oko; V (34 times) in site Štefanová in comparison to the Norway values. We find out statistical important decrease of concentration
N on all sites by comparison 2000/2005. The obtained data can be useful as a reference level for comparison with the future measurements of air pollution in the examined area and also for biodiversity study.
