Transport and Accumulation of Heavy Metals in Undisturbed Soil Columns
The podzolic soils of the Kola Peninsula, Russia, have in localised areas been highly contaminated with copper and nickel from smelting activities. Migration and retention of these metals were investigated in undisturbed soil columns irrigated with simulated background and polluted precipitation in order to study the temporal processes of retention and release within the soil. The mineral layer...
متن کاملInverse Estimation of Soil Hydraulic and Solute Transport Parameters from Transient Field Experiments: Heterogeneous Soil
While inverse parameter estimation techniques for determining key parameters affecting water flow and solute transport are becoming increasingly common in saturated and unsaturated zone studies, their application to practical problems, such as irrigation, have received relatively little attention. In this article, we used the Levenberg–Marquardt optimization algorithm in combination with the HY...
متن کاملEvaluating non-equilibrium solute transport in small soil columns.
Displacement studies on leaching of bromide and two pesticides (atrazine and isoproturon) were conducted under unsaturated steady state flow conditions in 24 small undisturbed soil columns (5.7 cm in diameter and 10 cm long) each collected from two sites differing in soil structure and organic carbon content in North Germany. There were large and irregular variabilities in the characteristics o...
متن کاملExperimental Investigation of Solute Transport in Large, Homogeneous and Heterogeneous, Saturated Soil Columns
Laboratory tracer experiments were conducted to investigate solute transport in 12.5-m long, horizontally placed soil columns during steady saturated water flow. Two columns having cross-sectional areas of 10 x IOcm’ were used: a uniformly packed homogeneous sandy column and a heterogeneous column containing layered, mixed, and lenticular formations of various shapes and sizes. The heterogeneou...
متن کاملPrediction of Dispersivity for Undisturbed Soil Columns from Water Retention Parameters
ity D/v (L), that can be related solely to characteristics of the porous medium (Fried and Combarnous, Dispersivity ( ) is a required input parameter in solute-transport 1971). Dispersivity is a required input parameter in conmodels based on the advection-dispersion equation (ADE). Normally is obtained from miscible-displacement experiments. This depentaminant transport models based on the ADE ...
