Název v původním jazyce

Fluxes of Arsenic in Soil-Water System at the Čelina-Mokrsko Gold District, Bohemian Massif

Popis výsledku v původním jazyce

We present a weathering mass balance of two small catchments, located within the Čelina-Mokrsko gold district (Central Bohemia) that has never been mined and, which is affected by serious As contamination as a consequence of arsenopyrite weathering. Mechanical and chemical weathering rates of rocks were estimated at 656 kg/ha/year and 172 kg/ha/year at the Mokrsko catchment and 329 kg/ha/year and 45 kg/ha/year at the Čelina catchment, respectively. The weathering rate of arsenopyrite was estimated at 1210 g/ha/year and 210 g/ha/year during the period of 2003-2004 in the highly As mineralized Mokrsko catchment and less As-mineralized Čelina catchment, respectively. Mass budgets of arsenic in soil of both catchments reveal that As has been accumulated in the soil of the Čelina catchment and depleted in the soil of the Mokrsko catchment during the sampling interval.
