ABSTRACT Selenium (Se) is an essential micronutrient for humans and animals and can be toxic when present in high concentrations in soil and water. Many soils in Gunnison and Uncompahgre River Basins in West-Central Colorado are formed from deposits derived mainly from weathered Mancos shale that have high concentration of Se and salts. Elevated concentrations of Se and salts were detected in streams and rivers in this area. The objectives were to determine the amount and distribution of… 

Mercury and selenium concentrations in fishes of the Upper Colorado River Basin, southwestern United States: A retrospective assessment

It is identified that species of management concern accumulate THg and Se to levels above risk thresholds and that fishes of the White-Yampa (THg) and Gunnison (Se) rivers are at the greatest risk in the UCRB.

Microbial communities across a hillslope‐riparian transect shaped by proximity to the stream, groundwater table, and weathered bedrock

A depth-resolved, hillslope to riparian zone transect study to identify factors that control how microorganisms are distributed and their functions within the East River, CO watershed, and expects that the drivers of community composition and metabolic potential identified will predict patterns across the larger watershed hillslopes system.

Taxonomically and metabolically distinct microbial communities with depth and across a hillslope to riparian zone transect

It is concluded that important ecosystem functions are strongly associated with the riparian zone, some of which may have crucial implications as to water quality and human health.



Selenium distribution in topsoils and plants of a semi-arid Mediterranean environment.

Selenium was determined from 25 topsoils and 25 plants in the semi-arid Central Spain where large extents of soils are developed on evaporitic materials. Some species of vegetation associated with

Detailed study of selenium in soil, representative plants, water, bottom sediment, and biota in the Kendrick Reclamation Project Area, Wyoming, 1988-90. Water Resources Investigation

In response to increasing concern about the quality of irrigation drainage and its potential effects on fish, wildlife, and human health, the U.S. Department of the Interior formed an interbureau

Concentrations and characteristics of selenium in soil samples from Dashan Region, a selenium-enriched area in China

Abstract In order to clarify the total selenium (Se) content and species of Se in the soils of Dashan Region, a typical Se-enriched area in China, 69 soil samples with different land-use purposes

Selenium in Hungary. The rock-soil-human system.

It was concluded that Hungarian rock-soil systems, especially the acid igneous rocks and the widely distributed young sediments with most of the agricultural activity, are low in Se, and the mean serum Se level of the blood samples were also low.

Selenium in Hungary

Selenium (Se) status of Hungarian rock-soil systems has been poorly investigated. The goal of this study was to get general information on the main features of Se geochemistry, and to have a brief

Bioaccumulation of selenium from natural geologic sources in western states and its potential consequences

Ecological impacts of water-quality problems have developed in the western United States resulting from the disposal of seleniferous agricultural wastewater in wetland areas. Overt effects of

Selenium retention in the organic matter of Swedish forest soils

SUMMARY Fractions of selenium present in the soil profiles of three Swedish podzols were analysed using a sequential extraction scheme to characterize Se distribution among the organic and

Microbial Transformations of Selenium and the Bioremediation of Seleniferous Environments

A major emphasis is placed on Se reduction and methylation/volatilization reactions because these processes are currently the most promising for transformation of toxic Se oxyanions into less toxic or biologically unavailable forms.

Reconnaissance investigation of water quality, bottom sediment, and biota associated with irrigation drainage in the Gunnison and Uncompahgre River basins and at Sweitzer Lake, west-central Colorado, 1988-89

During the last several years, there has been increasing concern about the quality of irrigation drainage and its potential harmful effects on human health, fish, and wildlife. This report describes
