Abstract
Atmospheric dust emissions can be а threat for the environmental and human health. Long-term
emission occurs in this area due to the Pb-Zn hydrothermal exploitation (Sasa and Zletovo mines) and copper
ore exploitation and flotation (Bučim mine), in the area of Bregalnica river basin. The present study proposes
a combined model based on: bioindication with moss species (Hypnum cupressiforme and Homolothecium
lutescens), and universal kriging mapping for determination of arsenic distribution. For that purpose, 149
moss samples were collected from the area, and both moss species were used interchangeably. At the same
sampling points, soil samples from the surface layer were also collected. Mass spectrometry with inductively
coupled plasma (ICP-MS) was used for determination of total arsenic content in moss and soil samples. Prior
to analysis, the samples were totally digested with the application of microwave system for samples digestion
for moss samples and open wet digestion was used for total dissolution of soil samples. Spatial distribution
maps were constructed for determination and localizing of narrower areas with higher contents of arsenic.
The content of arsenic in moss tissue (regarding air-born dust) ranges from 0.05 mg/kg to 4.28 mg/kg, while
distribution of arsenic in soil samples ranges from 3 to 261 mg/kg. Dominant lithogenic occurrence of arsenic
was correlated with areas of Neogene pyroclastites (volcanism).
