Experimental study on effect of dissolved organic matter on mobility of soil colloids
Soil colloids are widely distributed in underground environment. They can facilitate or retard the migration of pollutants in soils, depending on the mobility of the colloids.

Investigation of co-migration of heavy metal with colloid under preferential flow
Most of the heavy metal pollutants in soil come from external industrial and agricultural activities. Surface soil layer is the only access through which the heavy metal can migrate downward.

Frost Heave in Colloidal Soils [PDF]
We develop a mathematical model of frost heave in colloidal soils. The theory accounts for heave and consolidation while not requiring a frozen fringe assumption. Two solidification regimes occur: a compaction regime in which the soil consolidates to accommodate the ice lenses, and a heave regime during which liquid is sucked into the consolidated soil

To accurately evaluate the distribution and bioavailability of potentially toxic elements (PTEs) such as Cu and Cd in farmlands near a copper smelter, we determined the total concentrations (Cu-T and Cd-T), various speciation concentrations of Cu and Cd ...

Transport of Colloids and Colloid-facilitated Cadmium in a Sri Lankan Agricultural Soil
Naturally occurring colloids, particles of diameter < 2 μm, are ubiquitous in geo environments and can potentially facilitate transport of numerous contaminants in soil via colloid-facilitated transport (CFT).

Predicting the Rate Coefficients of Attachment and Detachment of Colloids in Saturated Porous Media
The transport behavior of pathogenic microorganisms and nanoparticles (NPs) in the subsurface is usually studied by performing laboratory soil column experiments.

Field-scale study of colloid transport in fracture flow from a sloping farmland of purple soil
To evaluate natural colloid transport potentials into groundwater,via fracture flow,a field-scale study was undertaken on a large sloping farmland plot(1 500 m2) in central Sichuan in the summer of 2013.

Colloids have a high adsorption capacity and can be mobile under preferential flow, and so may facilitate heavy metal migration. Heavy metal migration with soil colloids in a clayey soil under preferential flow conditions was investigated through ...
