The assessment of copper and zinc removal from highway stormwater runoff using Apatite II™

Creator:

Huang, Hsiao-Wen

Abstract:

Copper and zinc are heavy metals commonly present in highway stormwater runoff. Discharge of these metals to surface waters inhabited by sensitive aquatic species including threatened and endangered salmonids has necessitated the need for improved treatment techniques. Although copper is of the greater toxicological concern, zinc is often present at...

Statistical analysis and speciation modeling of copper in Oregon highway runoff

Creator:

Bloomquist, Don J.

Abstract:

Low levels of copper have been shown to impair the olfactory system of threatened and endangered (T&E) salmon, decreasing their predator avoidance behavior and likely increasing mortality. However, only dissolved copper (dissCu) present as the cupric ion (Cu2+) and weakly complexed species are truly bioavailable. Previous studies indicate the vast...

Comparison of Experimentally-determined and Model-estimated Attachment Efficiency for Predicting Nanoparticle Aggregation

Creator:

Kennard, Jasmin J.

Abstract:

The widespread use of engineered nanoparticles (ENPs) in industrial applications and consumer products makes their release to the environment inevitable. Understanding the aggregation behavior of ENPs is crucial to understanding their fate, transport and toxicology in aquatic systems. This study investigated the comparability of experimentally-determined and model-estimated attachment efficiencies for...
