Redistribution of cadmium and lead fractions in contaminated soil samples due to experimental leaching
Original language description
The sequential extraction procedure (SEP) is often applied to soils for identification of binding phases but rarely is it used to monitor binding dynamics temporally. In this study, contaminated soils were subjected to two different leaching scenarios, one analogous to a hydrostatic or stagnant water exposure, and one that represents a hydrodynamic event such as heavy precipitation. A four step SEP was applied before and after each stage of leaching and the adsorption dynamics of cadmium and lead were studied. In the hydrostatic experiment, removal of Cd and Pb occurred largely from the residual fraction (from initially >30%-zero Cd after the 720 h experiment, 40%-<20% Pb, and from 50%-20% Cd, >50%-40% Pb, from organic and mineral soil horizons respectively). There was a significant redistribution onto the Fe/Mn oxides (from initially 30%-60% Cd after 720 h, 40%-65% Pb, and from 15%-30% Cd, 45%-60% Pb for organic and mineral soils respectively). A significant redistribution of Cd onto
