The speciation of iodine in the salt impacted Black Butte soil series along the Virgin river, Nevada, USA
نویسندگان
چکیده
Salt-impacted soils occur in floodplains, wetlands and backswamps in arid climates. These soils become sinks or temporary storage sites for soluble salts and contaminants including agricultural chemicals, industrial pollutants and radionuclides such as I. The vertical distribution of I in the Black Butte soil series along the Virgin river was assessed and the distribution of I between I , IO 3 and organically bound I was determined. The speciation of I was compared to the organic C content, specific components of the organic C, and clay content. This study indicates that organic I was the most abundant form of I in these soil samples and that the content of organic I generally correlated to total organic matter and lignin (as measured by chemolysis) of the samples. 2008 Elsevier Ltd.

Rediscovering Rana onca: Evidence for Phylogenetically Distinct Leopard Frogs from the Border Region of Nevada, Utah, and Arizona
Remnant populations of leopard frogs within the Virgin River drainage and adjacent portions of the Colorado River (Black Canyon) in northwestern Arizona and southern Nevada either represent the reportedly extinct taxon Rana onca or northern, disjunct Rana yavapaiensis. To determine the evolutionary distinctiveness of these leopard frogs, we evaluated mitochondrial DNA (mtDNA) restriction site v...
متن کاملEvaluation of background geochemical speciation of heavy metals in overburden topsoil of bituminous sand deposit area, Ondo state, Nigeria
Metals are ubiquitous within the earth crust. However, the exceptional high-level concentration of heavy metals in the soil due to natural or anthropogenic activities and the chemical forms in which they exist determine the level of risk they portend to the environment. This work was aimed at determining the background level of the presence of seven priority toxic metals (Cr, Ni, Pb, As, Cd, Cu...
متن کاملBowen Ratio Estimates of Evapotranspiration for Tamarix Ramosissima Stands on the Virgin River in Southern Nevada
A Bowen ratio energy balance was conducted over a Tamarix ramosissima (saltcedar) stand growing in a riparian corridor along the Virgin River in southern Nevada. Measurements in two separate years were compared and contrasted on the basis of changes in growing conditions. In 1994, a drought year, record high temperatures, dry winds, and a falling water table caused partial wilt of outer smaller...

Salt cedar is widely spread out in most part of the country but there is lack of information about its symbiosis with arbuscular mycorrhizal fungi. Then, the main objective of this study was to evaluate the symbiosis of AMF with salt cedar and its affectability by distance from river and soil physiochemical properties. For this purpose, riparian Maroon forest width was divided to three location...
