Abstract

The presence of metals in the ambient air (ambient dust) in the urban environment is a frequent
subject for research, and so far it has been worked out in many urban centers in the world. The systematic research for
the contents of the ambient dust in the city of Skopje is not made before, so we cannot present such information.
However, it should be emphasized that such information which refer on the contents of the urban dust exist in many
towns, but that information is very changeable depending on the seasons in which the data is measured. As an example,
on the basis of a large number of researches the metals which are present in the urban dust are divided in three groups:
– Urban elements (Ba, Cd, Co, Cu, Mg, Pb, Sb, Ti, Zn). – Natural elements (Al, Ga, La, Mn, Na, Sr, Th, Y) – Elements
with mixed background (Ca, Cs, Fe, Mo, Ni, Rb, Sr, U). There is accepted opinion that the background of the urban
elements is primarily connected with the development of the traffic, the processes of corrosion of the materials build
in the objects in the towns (buildings, houses, roads, etc.) as well as the emission of dust which appears in the soils,
and fields with no grass. In order to be able to make any correlation of the obtained data which refer to a small number
of measured samples (only of two locations) many deeper researchers are needed. From the other side, the influence of
the contents of dust (as well as the ambient air) upon the health of the people is a topic which requests more serious
and longer measures.
Key words: barium, urban elements, natural elemnet
