The mobility of heavy metals in soils in the Krušné Hory and Slavkovský Les mountains.

In the North Bohemian forest soils the total content and EDTA, HAc and H2O-extractable portions of Cr, Co, Ni, Cu, Pb and Zn were investigated. Increased concentration of Pb in topsoils, in comparison with subsoils, is the result of air pollution. The extractable portion of all studied heavy metals is higher in topsoil than in subsoil.
