Mechanisms of trace metal transport in rivers
Gibbs RJ. 1973. Mechanisms of trace metal transport in rivers. Science. 180(4081):71-73
Evaluations are presented of the amounts of Fe, Ni, Cu, Cr, Co, and Mn transported by the Amazon and Yukon rivers. The trace metals were analytically partitioned among the transport phases: in solution, ion exchange, organic materials, metallic coatings, and crystalline solids. All the samples of water and suspended sediments were taken from the rivers at 60% of main channel depths and upstream from any influence of saline water. The trace metals distribution for both rivers is similarly proportioned with copper and chromium transported mainly in the crystalline solids, manganese in coatings, and iron, nickel, and cobalt distributed equally between precipitated metallic coatings and crystalline solids.
