Název v původním jazyce

Cadmium transport in structured soil under conditions of climate change

Popis výsledku v původním jazyce

Cadmium penetration into a sandy-loam soil during the field ponded infiltration at Kralovska luka site in Southern Slovakia was observed in a controlled experiment. Transport of cadmium adsorbed on soil particles < 0.01 mm was examined using radioactivetracer techniques in laboratory batch tests. Quite deep 115Cd penetration (65 cm beneath the soil surface) gives evidence of the particle-facilitated transport of cadmium through preferential pathways. More than 40% of the applied cadmium penetrated deeper than 10 cm. The field experiment was analyzed using both conventional single-permeability approach (based on Richards' equation for water flow and advection-dispersion equation for solute transport) and dual-permeability approach. The latter approachallowed us to simulate more adequately the particle-facilitated transport. The simulation results obtained with the dual-permeability model show close agreement with the measured cadmium penetration.
