Health effects of toxic organic compounds from coal; the case Balkan endemic nephropathy (BEN) Health effects of toxic organic compounds from coal; the case Balkan endemic nephropathy (BEN)
Balkan endemic nephropathy (BEN) is a serious kidney disease that occurs only in clusters of rural villages located in tributary valleys of the Danube River in the Balkan Peninsula. It is believed that at least 25,000 persons are suffering from BEN or are suspected of having the disease and that the total number of people at risk may exceed 100,000. BEN was first described as a distinct...

A geostatistical approach to predicting sulfur content in the Pittsburgh coal bed A geostatistical approach to predicting sulfur content in the Pittsburgh coal bed
The US Geological Survey (USGS) is completing a national assessment of coal resources in the five top coal-producing regions in the US. Point-located data provide measurements on coal thickness and sulfur content. The sample data and their geologic interpretation represent the most regionally complete and up-to-date assessment of what is known about top-producing US coal beds. The sample...

The Upper Pennsylvanian Pittsburgh coal bed: Resources and mine models The Upper Pennsylvanian Pittsburgh coal bed: Resources and mine models
The U.S. Geological Survey recently completed a digital coal resource assessment model of the Upper Pennsylvanian Pittsburgh coal bed, which indicates that after subtracting mined-out coal, 16 billion short tons (14 billion tonnes) remain of the original 34 billion short tons (31 billion tonnes) of coal. When technical, environmental, and social restrictions are applied to the remaining...

Use of 234U and 238U isotopes to identify fertilizer-derived uranium in the Florida Everglades Use of 234U and 238U isotopes to identify fertilizer-derived uranium in the Florida Everglades
Surface water and peat in the northern Everglades have very low natural concentrations of U and are therefore sensitive to the addition of small amounts of U from anthropogenic sources such as fertilizer. Peat samples collected along a nutrient gradient in the northern Everglades have unusually high concentrations of U (> 1 ??g/g, dry basis) and also have a distinctive 234U/238U activity...

Geochemistry of sulfur in the Florida Everglades: 1994 through 1999 Geochemistry of sulfur in the Florida Everglades: 1994 through 1999
In this report, we present data on the geochemistry of sulfur in sediments and in surface water, groundwater, and rainwater in the Everglades region in south Florida. The results presented here are part of a larger study intended to determine the roles played by the cycling of carbon, nitrogen, phosphorus, and sulfur in the ecology of the south Florida wetlands. The geochemistry of...
