This work presents result of research content $Zn$ i $Pb$ in soils and sediments in Biała Przemsza valley. Samples were taken on Oct. 22, 2011 year in the Sławków. It was done five drilling (S I, S II, S III, S IV, S V) and taken 61 samples. The collected sediment measured temperature, pH, Eh and PEW. The content of water, organic matter and carbonates measured by weight method. For chosen samples was performed BCR sequential extraction. It served determine the potential mobility of $Zn$ and $Pb$ in the analyses samples. Studies have shown that the most mobile part of the fraction $Zn$ in sediments is 7 - 63%, in the soils of 7 - 38% and $Pb$ 3 - 70% of the sediment, and 6 - 62% of the soils. The highest absolute concentrations of metals in the most mobility form was found in soils closest to the river bed. As you move away from the trough of the show a downward trend.

The purpose of this study is to determine the zinc and lead contamination of soils in the surroundings of waste dump in the Bukowno region, distribution of the analyzed metals in the vertical soil profiles, as well as defining the potential mobility of Zn and Pb in the environment. In the thesis potential emission sources and the state of environment contamination with analyzed metals were discussed. Conducted research showed, that the soil in the surroundings is very heavily polluted with zinc and lead. The participation of mobile forms of metals were found, which probably migrated from surface into deeper layers of soils.
