Natural and anthropogenic sources of metals, metalloids, and rare earth elements are ubiquitous in the environment, and elevated concentrations of these constituents are often found in fresh waters. These elevated concentrations have wide-ranging implications, including potential lethal and sub-lethal effects on aquatic biota, adverse effects on water used for drinking water and irrigation, and overall degradation of water bodies used for recreation and other purposes. This session is devoted to research that aims to characterize and quantify (1) source areas which contribute constituent mass, (2) transport processes which move constituents from source areas to and through affected water bodies such as streams, rivers, lakes, wetlands, and groundwater, and (3) biogeochemical processes which attenuate and/or transform constituents. Submissions from a variety of subfields are welcome, including research on the effects of mining, metals from consumer products including nanoparticles, studies of stormwater runoff, and industrial sources of contamination.
