Abstract (in english)
   The biogeochemical study was carried out at the Lesni potok (LP) catchment, Central Bohemia, Czech Republic. The ecosystem was impacted by heavy acid deposition during the industrial development in 1980-1990. The catchment is forested mostly by two tree species, Norway spruce and European beech. The Be concentration in the granite bedrock is 12.6 mg kg-1. Elevated concentration of Be (5.4 ?g L-1) in surface waters is a result of its mobilization from the soils (3.9 mg kg-1) and weathered rock by acid precipitation. As the pH of the precipitation and consecutively pH of the surface waters is increasing in the Czech Republic, the Be concentrations in the surface waters gradually decrease. Groundwater with high pH values contains lower concentrations of Be (0.17 ?g L-1) than surface waters. The monitoring of Be in the environment is important with respect to its possible harmful effects on aquatic biota and root systems of the plants.
