Abstract (in english)
   The biogeochemical study was carried out at the Lesní 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 species, Norway spruce and European beech. The Be concentration in the granite bedrock is 12.6 mg kg-1. The plagioclase contains the highest Be concentrations out of the rock-forming minerals. Elevated concentrations of Be (5.4 ug 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 um L-1) than surface waters. The soils at prone area depletd in Be compared to the soils in the riparian zones.
   The vegetation located on the prone area contains lower concentrations of the Be than vegetation at riparian zones. The monitoring of Be in the environments is important wwith respect to its possible harmful effects on aquatic biota and root systems of the plants
