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

The Immobilization Mechanism of Inorganic Amendments on Cu and Cd in Polluted Paddy Soil in Short/Long Term [PDF]
ToxicsThis study investigated the impact of soil colloidal characteristics on the transfer patterns of different Cu and Cd speciation in contaminated soil treated with three different amendments: lime (L), zero-valent iron (ZVI), and attapulgite (ATP).

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).

Frost Heave in Colloidal Soils [PDF]
SIAM Journal on Applied Mathematics, 2011 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

Quantitative characterization of non-DLVO factors in the aggregation of black soil colloids
Scientific Reports, 2022 The variable role and fate of soil colloids under different environmental conditions are derived from their dispersion and aggregation properties. In this work, dynamic and static light scattering were used to characterize the original size, aggregation ...
