THE DEGREE OF POLLUTION WITH HEAVY METALS OF FALLOW SOILS IN RURAL ADMINISTRATIVE UNITS OF PSARY AND PLOKI IN POLAND

Volodymyr Pohrebennyk, Agnieszka Petryk

Abstract

The article aims at analysing the content of heavy metals in the soils of two rural administrative units of the municipality of Trzebinia namely Psary and P?oki which are located in the Silesian-KrakпїЅw Upland, in the western part of the Malopolska province, in Poland. The analysis of soil material was based on the determination of granulometric composition of the soil with the use of the Casagrande method modified by PrпїЅszy?ski (according to the industry standard BN-78/9180-11)[1], soil reaction in 1M KCl and in water with the use of potentiometric method, electrolytic conductivity of the soil with the use of conductometric method, content of organic matter in soil by its annealing using the modified Tiurin method, the total heavy metals content in the soil using FAA method.These areas have been heavily transformed by the mining and processing industries. It was found that the mean content of lead, cadmium and zinc in the soils of Psary and P?oki exceeded the permissible concentrations of these elements according to the regulations adopted by the Polish legislator [2] for agricultural land. The mean copper content in the soils of the aforementioned rural administrative units did not exceed the concentration of the element stated in the ministerial standards. The research conducted on fallows of the rural administrative units showed the positive direction of the relationship between the content of heavy metals and organic matter content as well as pH value in the soil layer of 0-20cm.
