Elevated content or heavy metals in soils is characteristic of the Dąbrowa Górnicza region. The highest concentrations of lead. cadmium and zinc exceed herc 650, 15, and 1000 mg/kg of soil, respectively. Samples of soi I from selected sites underwent the speciation analysis with the use of the Tessier method. modified according to Kersten and Forstner. Results of the investigations proved the highest concentrations or these metals in the area of Trzebiesławice. They occur here in the strongly bound forms and, mainly, their occurrence is related to presence of limestone rocks. The greatest amounts of these metals in easily assimilable to plant forms occur within the area of the town of Dąbrowa Górnicza. The most probable source ot· most of these heavy metals in soils are here contaminants emitted by the industry, mainly by the metallurgy. In the vicinity of the town of Błędów, mainly sandy soils occur, characteristic or which is low content of considered metals. Weak sorption capacities of these soils account for relatively good cxtractability of the three metals. In soils from the Lęka area, strong binding of these metals was confirmed. Occurrence or cadmium should be of special attention because this metal occurs as built in the crystal lattice of minerals.

In Agricultural and Industrial Works FARMUTIL HS at Śmiłów were "cleaner production" program has been pul in practice, elimination of odors occurring during production of the meal and bone meal is of vital importance. Conccnlrations and emissions of lola! dust, organic substances in form of gas and vapors (as total organic carbon), hydrogen chloride, fluorine chloride, sulphur and nitrogen dioxides, carbon monoxide, heavy metals, polychlorinatcd dibcnzodioxins and dibcnzofurans were measured al emitters of the piani for thermal disposal of odors from the production of the meat and bone meal. The results of measurements and analyses of the composition of the flue gas emitted lo the atmosphere revealed that the concentration of harmful chemical compounds was low, lower than the permissible values defined in the standards.
