Comparative Floc-Bed Sediment Trace Element Partitioning Across Variably Contaminated Aquatic Ecosystems
Abstract
Significantly higher concentrations of Ag, As, Cu, Ni and Co are found in floc compared to bed sediments across six variably impacted aquatic ecosystems. In contrast to the observed element and site-specific bed sediment trace element (TE) partitioning patterns, floc TE sequestration is consistently dominated by amorphous oxyhydroxides (FeOOH), which account for 30-79% of floc total TE concentrations, irrespective of system physico-chemistry or …
