Abstract

In the last decade there has been a research expansion of methodologies that establish fast and effective methodological approaches for monitoring atmospheric deposits. Air pollution has been alarming in recent decades globally. The distribution of microparticles originating from different emission sources poses a huge threat to the health of the human population. The number of researches done so far is huge, but the most common problem is to find a fast, effective and transparent research model. In this research we proposed a model, which can serve as an initial research for subsequent screening models. This approach, unlike the typical analysis with existing chemical instrumentation techniques, does not require chemical destruction of the sample and additional costs for chemical agents. But on the other hand this model is suitable for screening of
large areas in order to identify criticaly affected areas with anthropogenic born elements. Bryophytes are a very useful tool for monitoring atmospheric deposition. Moss samples of Hypnum cupressiforme (Hedw.) and Homalothecium lutescens (Hedw.) were collected at the critical mining areas in the Eastern part of the Republic of North Macedonia. The unique structure and physiology of mosses allows dust particles to remain trapped on their surface. With the help of electron microscopy, the composition of anthropogenic elements in the dust particles trapped
on the surface of these structures was monitored. Chemical characterization of the moss surface in comparison with the deposited dust. Analyzes have shown that both moss species have similar surface adsorption to dust particles, as well as insignificant variability in the chemical composition. Hypnum cupressiforme dominate in the background content for the biogenic elements carbon and oxygen, macroelements Mg, Al, Si, K, Ca, and microelements Fe, Cu and Zn.
