The dominant contribution on wet deposition of water-soluble main ions in the South-Eastern Adriatic region

The results of content of water-soluble ions measured in 604 samples of precipitation collected in South-Eastern Adriatic region during 6 years have been analyzed. The HYSPLIT model was used to study the air mass paths. Although the ion concentrations of investigated ions in precipitation of air masses from the continental parts of Europe were significant, the total wet deposition is dominated by precipitation coming over the Mediterranean Sea. The sea salt components are significantly correlated. The correlations between Ca2+ and Mg2+, Ca2+ and SO4 (2-) and Ca2+ and K+ indicate the main terrigeneous ions
