ABSTRACT

There are selected regions with a certain quality of a situation or a tendency of changes
of environmental components. The significantly changes, in these areas are observed at
soils, as the basic component of environment at which is man biologically contacted.
The significantly chemical degradation of soils - acidification and contamination of
soils with heavy metals - in loaded regions – the middle Spis region are showed. The
middle Spis region is area at Slovak republic with deteriorated or heavily deteriorated
environment in environmental regionalization. Soil contamination by heavy metals is
especially caused by ore mining, processing and treatment. Systematic monitoring of
soils contamination with heavy metals in such loaded areas is necessary. Geographical
information systems (GIS) belong to environmental monitoring systems. They offer
tools and methods by which is possible to present a development of changes at the
quality and at the contamination of soils finding at surroundings of the source as well as
to define areas for revitalisation.

Soil samples from the middle Spis region were collected to determine of the influence
of anthropogenic load on bioavailability of metals from soil. According to obtaining
results there were made a suitable database. By synchronization of the made database
with GIS well-arranged transparent maps were created. The computer programme Arc
View GIS was used as a suitable programme package for the selected area.

Keywords: monitoring, heavy metal, contamination, soil, loaded region, geographical information systems
