Název v původním jazyce

Parameterisation and modelling of cadmium transport in soils under conditions of climate change

Popis výsledku v původním jazyce

Cadmium penetration into a sandy-loam soil during the field ponded infiltration at Kráľovska lúka site in Southern Slovakia was observed in a controlled experiment using a radioactive tracer technique. Quite deep 115mCd penetration (65 cm beneath the soil surface) gives evidence of the particle-facilitated transport of cadmium through preferential pathways, when more than 40% of the applied cadmium moved deeper than 10 cm. Adsorption of cadmium on all the soil particles, the particles > 0.01 mm and theparticles < 0.01 mm were estimated in laboratory batch tests using the radioactive tracer technique, and the distribution coefficients were calculated for both the matrix and preferential flow domains. Data from the field experiment were used to calibrate the dual-continuum model S1D Dual. The model was then used for predicting cadmium penetration into the soil in Kalinkovo, Macov and Jurová during a simulated heavy-rain event.
