Understanding Selenium Mobility by Sorption and Extraction Processes in Surface Coal Mine Spoil
Surface coal mine spoil was studied to evaluate selenium (Se) mobility and solubility using batch experiments, column-Ieachmg techniques, and sequential and individual extraction processes. Both selenite and selenate followed linear isotherm patterns at relatively lower Se treatments, whereas over a broader solution Se concentraton range the sorption mechanism followed the Lanpuir model. The va...

متن کاملRole of Natural Organic Solutes on the Sorption of Selenium by Coal Mine Backfill- Core Samples from the Powder River Basin, Wyoming
Concentrations of dissolved selenium (Se) as large as 330 pg L-' have been detected in water samples &om bacW aquifers in the southern Powder River Basin (PRB) of northeastern Wyoming. During d a c e coal mining, rock mstwial overiymg the coal is redistributed in relation to its original stratigraphic position; exposure of the prewiously buried material to surface oxidizing conditions decreases...
متن کاملGeochemical Processes Affecting the Mobility of Dissolved Selenium in Surface Coal Mine Backfill Environments
During surface Fadlelmawla', K.J. Reddf, and G.F. Vance3 coal mining, rock material overlying the coal is redistsibuted with respect to its original stratigraphic position. Oxidation of the redistributed backfill material may release dissolved selenium (Se) to groundwater in backfill systems. This study was initiated to examine the chemistry of Se in the groundwater backfill environment. Both b...
متن کاملForest to reclaimed mine land use change leads to altered ecosystem structure and function.
The United States' use of coal results in many environmental alterations. In the Appalachian coal belt region, one widespread alteration is conversion of forest to reclaimed mineland. The goal of this study was to quantify the changes to ecosystem structure and function associated with a conversion from forest to reclaimed mine grassland by comparing a small watershed containing a 15-year-old r...
