The aim of this work is to show the importance of monitoring the hygiene quality evaluation of soil profile in the Slovak Republic area. In the past, when no emphasis was laid on ecology, as it is nowadays, there was an uncontrolled emission of pollutants from different fields of anthropogenic activities. The consequences are manifested even today, and immediate and expensive solutions are much needed.In this work, the results of the research on the degree of heavy metal contamination in the soil profile as well as plant availability have been presented, which depended on the soil reaction in the 'Štiavnica Hills' and 'Žitný ostrov' areas. The choice of these areas is related to specific areas mentioned above that are characteristic of anthropogenic activity, besides factors such as natural (geochemical) contamination and intensive agricultural activity.All the soil samples were analysed to give a changeable soil reaction. Analyses on heavy metal in the aqua regia extract (total content) that is, risky elements in their mobile form contents in the NH₄NO₃ c = 1 mol • dm⁻³ leach and humus content according Tjurin were conducted.
