The continuing medical mystery of Balkan Endemic Nephropathy The continuing medical mystery of Balkan Endemic Nephropathy
Balkan Endemic Nephropathy (BEN) is a disease of subtle onset and insidious progression that typically occurs between the 4th and 6th decade in long‐resident individuals in highly specific geographic locations of the Balkan region and affects 1 – 5% of the population. Though it does not follow typical Mendelian genetics, there is a familial pattern of occurrence. Although residents may...

Atmospheric particulate matter in proximity to mountaintop coal mines: Sources and potential environmental and human health impacts Atmospheric particulate matter in proximity to mountaintop coal mines: Sources and potential environmental and human health impacts
Mountaintop removal mining (MTM) is a widely used approach to surface coal mining in the US Appalachian region whereby large volumes of coal overburden are excavated using explosives, removed, and transferred to nearby drainages below MTM operations. To investigate the air quality impact of MTM, the geochemical characteristics of atmospheric particulate matter (PM) from five surface...

Relationships between water and gas chemistry in mature coalbed methane reservoirs of the Black Warrior Basin Relationships between water and gas chemistry in mature coalbed methane reservoirs of the Black Warrior Basin
Water and gas chemistry in coalbed methane reservoirs of the Black Warrior Basin reflects a complex interplay among burial processes, basin hydrodynamics, thermogenesis, and late-stage microbial methanogenesis. These factors are all important considerations for developing production and water management strategies. Produced water ranges from nearly potable sodium-bicarbonate water to...

Organic substances in produced and formation water from unconventional natural gas extraction in coal and shale Organic substances in produced and formation water from unconventional natural gas extraction in coal and shale
Organic substances in produced and formation water from coalbed methane (CBM) and gas shale plays from across the USA were examined in this study. Disposal of produced waters from gas extraction in coal and shale is an important environmental issue because of the large volumes of water involved and the variable quality of this water. Organic substances in produced water may be...

The effect of coal bed dewatering and partial oxidation on biogenic methane potential The effect of coal bed dewatering and partial oxidation on biogenic methane potential
Coal formation dewatering at a site in the Powder River Basin was associated with enhanced potential for secondary biogenic methane determined by using a bioassay. We hypothesized that dewatering can stimulate microbial activity and increase the bioavailability of coal. We analyzed one dewatered and two water-saturated coals to examine possible ways in which dewatering influences coal...

Microbial production of natural gas from coal and organic-rich shale Microbial production of natural gas from coal and organic-rich shale
Natural gas is an important component of the energy mix in the United States, producing greater energy yield per unit weight and less pollution compared to coal and oil. Most of the world’s natural gas resource is thermogenic, produced in the geologic environment over time by high temperature and pressure within deposits of oil, coal, and shale. About 20 percent of the natural gas...
