Abstract: In this paper, the sediment‐side abiotic mechanisms for contaminant transport across the sediment‐water interface of rivers are compared. The transport processes considered include molecular diffusion, colloidal diffusion, ...

Abstract: Organic colloids resulting from sediment diagenesis in porewaters are transported across the sediment-water interface via Brownian diffusion. The sediment selected for this study was from the University Lake, Baton Rouge, ...
