The goal is both to summarize information obtained from the literature on the properties of lead and its geochemical position especially in forest soils and the specific contaminated site to assess the isotopic signatures as the likely origin of lead in soil study area. Compiled a literary review mainly concerns the influence, resources and effects of lead on the environment, the characteristics of the soil, their chemistry and their degradation. The experimental section describes the characteristics of the sampling sites, techniques of collecting and processing samples for analysis, the chemicals used and the analysis results. EDTA-extractable content (bioavailability) of lead in soil samples is the most accumulated in the humus (H) organic horizons, because they have the greatest sorption capacity. We found average levels of EDTA-extractable lead in forest soils assessed range from 8.5 to 28.6 DM with a mean of 17.6 DM only three of the eight sampling sites (Large niva, and East Hill Chlustov Radvanovické saddle spruce forest) exceed found containing 30 -1 . Observed isotopic ratios in large floodplain locations (from the spruce forest east Lenora) and Radvanovické saddle (spruce forest and beech wood from south of Lenora) are similar to those already previously identified signature of lead in river sediments by Lenora.
