coal zone in Wyoming and Montana. Coal from the Wyodak-Anderson coal zone is produced from 23 mines in the Powder River Basin. This coal is utilized for electric power generation at power plants in 26 states. The Wyodak-Anderson coal is sometimes blended with higher sulfur coal to . Soil geochemistry. Several locations in both the Champ Mine (CM; 6 previously mined and reclaimed locations plus one nonmined reference location) and Mountain Fuel Mine (MFM; 7 reclaimed locations plus one nonmined location) were sampled over two summers (see Fig. S1 in the supplemental material) in an attempt to encompass the range of biological, geochemical, and physical conditions on the.

Request PDF | Environmental geochemistry of selenium in Chinese coal | Selenium is one of the volatile elements in coal. With the mining and utilization of coal, selenium is largely released into. Selenium (Se), an animal toxicant and aquifer contaminant, occurs in coal mine environments of Wyoming.
There is a paucity of information on solution-phase Se speciation in mine soils. The objectives of this study were to compare Se extraction efficiencies of various reagents and to characterize SeO2– 3 (selenite), SeO2– 4 (selenate) and organic Se components in these extracts.
Se in ground water after mining, Wyoming, U.S.A. FIELD AND ANALYTICAL METHODS Rock sample collection Continuous core samples were collected from all the mine sites; however, only chip samples could be obtained from a drill site in the backfilled spoil material at coal mine B.
Sample depths ranged from. This paper elaborates soil, water, and lettuce contamination status with respect to selenium, sulphur, trace metals, and BTEX (benzene, toluene, ethylbenzene, and xylenes) in a coal-based area (Raša Bay, Adriatic Sea, Croatia).
A local coal-fired power plant polluted soil with S, Se, Cd, and PAHs due to the combustion of domestic superhigh-organic-sulphur coal. Elevated levels of selenium (Se) were detected downstream from the five open pit coal mines in the Elk River Valley, British Columbia.
Se is an essential nutrient but, in excessive amounts, it may cause teratogenic deformities and reproductive failure in fish and birds. To provide mine operators in the Elk River Valley with the information needed to assess the risk of Se release from waste.
A comparison of different soil environments containing various vegetation types also suggested that, for a plant containing 5 mg/kg Se, the soil Se status would be highest in abandoned mine lands.
In the western United States, elevated selenium (Se) levels in soil have resulted in documented cases of ruminant fatalities. This is due to the ingestion of Se-hyperaccumulating vegetation growing on previously reclaimed phosphate mine soils. A field-scale analysis was first.
