   Biogeochemistry of the anthropogenic contaminants As, Be, Cd, Cu and Pb was studied in the experimental Lesni potok catchment in central Bohemia. Bedrock, as well as the soil cover, are enriched by As, Be and Pb. The enrichment of Cu and Pb in topmost layers of the soil profile arc due to low mobility of elements, metabolic cycling by vegetation (Cu), and anthropogenic emissions (Pb). The content of As and Cd is more or less evenly distributed with depth, and in to a certain extent controlled by content of the soil clayey fraction.Atmospheric (mostly anthropogenic) inputs of As, Pb and Cu have been considerable. The distribution of elements between the solid and liquid phases depends on pH and Eh of system. Mobility of Pb and Cu is low, what results in their gradual accumulation in soils. Solid forms of As become mobile under reducing conditions.
