Transport of Colloids and Colloid-facilitated Cadmium in a Sri Lankan Agricultural Soil
Journal of Water and Environment Technology, 2023 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).

Effect of Chemical and Physical Heterogeneities on Colloid-Facilitated Cesium Transport
Journal of Contaminant Hydrology, 2018 A set of column experiments was conducted to investigate the chemical and physical heterogeneity effect on colloid facilitated transport under slow pore velocity conditions. Pore velocities were kept below 100 cm d-1 for all experiments. Glass beads were packed into columns establishing four different conditions: 1) homogeneous, 2) mixed physical ...

A Colloid-Facilitated Transport Model With Variable Colloid Transport Properties
Geophysical Research Letters, 2007 Anomalous contaminant transport velocities in groundwater for species generally considered to be immobile are often attributed to the mechanism of colloid‐facilitated transport. In some of the field observations attributed to colloid facilitation, an extremely small fraction of the total contaminant mass introduced to the groundwater is detected ...

Effects of transient flow conditions on colloid-facilitated release of decabromodiphenyl ether: Implications for contaminant mobility at e-waste recycling sites [PDF]
Eco-Environment & HealthPolybrominated diphenyl ethers (PBDEs) are ubiquitous contaminants, especially in the soil and groundwater of contaminated sites and landfills. Notably, 2,2′,3,3′,4,4′,5,5′,6,6′-decabromodiphenyl ether (BDE-209), one of the most frequently and abundantly

Colloid-Facilitated Transport of Radionuclides Through the Vadose Zone [PDF]
, 2003 In the previous reporting period, we have clarified the qualitative mineral transformation pathways when Hanford sediments are reacted with caustic Hanford tank waste. The major finding was that cancrinite, sodalite, zeolite A and allophane form when Hanford tank waste leaks into subsurface sediments. Cancrinite and sodalite are the most stable phases.

Frontiers in Forests and Global Change, 2021 Phosphorus (P) is preferentially bound to colloids in soil. On the one hand, colloids may facilitate soil P leaching leading to a decrease of plant available P, but on the other hand they can carry P to plant roots, thus supporting the P uptake of plants.

Saturated Zone Colloid-Facilitated Transport [PDF]
, 2001 The purpose of the Saturated Zone Colloid-Facilitated Transport Analysis and Modeling Report (AMR), as outlined in its Work Direction and Planning Document (CRWMS M&O 1999a), is to provide retardation factors for colloids with irreversibly-attached radionuclides, such as plutonium, in the saturated zone (SZ) between their point of entrance from the ...
