Impact of copper smelter emissions on two subalpine ecosystems near Anaconda, Montana : preliminary report

Creator:: Walsh, Natalie, Bissell, Gael, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Preliminary analysis of data from this study in the mountains southwest of the Anaconda Copper Smelter, an industrial source of SO2 and heavy metal particulate, reflects a complex pattern of pollutant impact. The differential effect of smelter emissions on plant life in the study area is best explained by the...

Limiting copper loss from treated wood in or near aquatic environments

Creator:: Mitsuhashi Gonzalez, June M.
Abstract:: Copper migration from treated wood has created concerns within the environmental community because of the potential effects of this heavy metal on aquatic organisms. Migration can be limited, to some extent, by more controlled treatments and by post-treatment processing, but these actions cannot completely overcome the problem. An alternative approach...

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...

Impact of fluorides and insects on radial growth of lodgepole pine near an aluminum smelter in Northwestern Montana : a preliminary inquiry

Creator:: Carlson, Clinton E., Hammer, William P., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: A study was conducted in summer of 1973 to assess impact of fluoride-insect damage on radial growth of lodgepole pine near the Anaconda Aluminum Company at Columbia Falls, Montana. Statistically significant growth losses attributed primarily to the effects of fluorides were found in 40 14 of 17 unmanaged stands for...

Measuring the Sustainability of a Proposed Copper Mine in Arizona : A Temporal Comparison

Creator:: Handy, John B.
Abstract:: A proposed copper mine in Arizona has the potential to be the largest copper producing mine in North America. It is expected to produce over a billion pounds of copper per year, and individually produce more than half of the United State's demand for copper. The operation claims to be...

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...

Geomorphic and Climatic Controls on Water Temperature and Streambed Scour, Copper River Delta, Alaska : Implications for Understanding Climate Change Impacts to the Pacific Salmon Egg Incubation Environment

Creator:: Adelfio, Luca A.
Abstract:: Pacific salmon (Oncorhynchus spp.) face numerous challenges associated with climate change. Most research has emphasized the potential effects of elevated summer water temperatures; however, climatic changes are also projected to significantly alter incubation and rearing habitats during the late autumn, winter, and spring months ("the incubation period"). Along the southern...

Biochemical and physiological indicators of behavioral impairment in salmonids exposed to chlorpyrifos and copper

Creator:: Sandahl, Jason
Abstract:: The purpose of this work was to determine if environmentally-relevant concentrations of chlorpyrifos and copper, two commonly detected chemicals in Western surface waters, can negatively impact the biological health of salmonids. Both compounds are highly neurotoxic to fish, but each with distinct biological target sites and mechanisms of action. We...

Copper Speciation in Wastewater-Impacted Surface Waters

Creator:: Mosbrucker, Ariel M.
Abstract:: This study investigates the relationship between total and ionic copper in samples taken from the Tualatin River and wastewater treatment facilities (WWTFs) that discharge into the Tualatin River. Copper speciation was analyzed by determining conditional stability constants and densities of copper binding ligands on the dissolved organic matter (DOM) in...
