Longtime geochemical evaluation of anthropogenic element’s distribution in the air using deposited attic dust

By Biljana Balabanova, Trajče Stafilov and Robert Sajn

Abstract

Atmospheric deposition poses significant ecological concerns. In this work attic dust was examined as historical archive of anthropogenic emissions, with the aim of elucidating the pathways of enrichments associated with exploitation of Cu, Pb and Zn minerals in the Bregalnica river basin region. Attic dust samples were collected from 84 settlements. At each location for attic dust sampling, topsoil samples from the house yards were also collected. Mass spectrometry with inductively coupled plasma (ICP-MS) was applied as analytical technique for determination of Ag, Bi, Cd, Cu, In, Mn, Pb, Sb, Te, W and Zn. The Universal Kriging method with linear variogram interpolation was applied for the construction of spatial distribution maps. This geochemical association links typical elements which are normally associated with air pollution (Cd-Pb-Zn), and usually are not influenced by lithological background. This investigation fortifies an extended anthropogenic association (Ag, Bi, In and Mn) that implement some other anthropogenic activities such as agricultural activities (use of urban sludge, manure and fertilizers) or their occurrence can be a secondary affection from mine poly-metallic pollution. Spatial patterns showed intensive deposition in the areas of Pb-Zn mining activities (“Sasa” and “Zletovo” mines) and copper mine “Bučim”. Long-distance distributions of higher contents of these elements from the mines were not detected
