Dissolved selenium in surface and subsurface waters of the Rawanwara Colliery area of Penchvalley Coalfield, and its impacts on human health
Costs and benefits of building energy efficiency are estimated as a means of reducing greenhouse gas emissions in Pittsburgh, PA and Austin, TX. The analysis includes electricity and natural gas consumption, covering 75% of building energy consumption in Pittsburgh and 85% in Austin. Two policy objectives were evaluated: maximize GHG reductions given initial budget constraints or maximize social savings given target GHG reductions. This approach evaluates the trade-offs between three primary and often conflicting program design parameters: initial capital constraints, social savings, and GHG reductions. Results suggest uncertainty in local stocks, demands, and efficiency significantly impacts anticipated outcomes....
Geochemical Features of Water-Rock Interactions at the Sulphur Bank Mercury Mine, Lake County, California
Assessment of DNA damage in coal open-cast mining workers using the cytokinesis-blocked micronucleus test and the comet assay
Coal mining is one of the most important causes of environmental pollution, as large quantities of coal dust particles are emitted. Colombia-South America has large natural coal reserves and "El Cerrejón" is the world's largest open-cast mine located in the northern department of Guajira. The aim of the present study was to evaluate genotoxic effects in a population exposed to coal residues from the open-cast mine "El Cerrejón". 100 exposed workers and 100 non-exposed control individuals were included in this study. The exposed group was divided according to different mining area activities: (i). Transport of extracted coal, (ii). Equipment field maintenance, (iii). Coal stripping and, (iv). Coal embarking.

All mining lease boundaries found in the Powder River Basin. This data layer has many overlapping polygon features and is thus more applicable if used as Arc/Info regions. Each region is attributed relating to the name of the coal mine utilizing the leased area. The data layer was originally produced by the Bureau of Land Management and distributed in an ASCII text format which was then converted into a GIS layer.
Source of Anthropogenic Heavy Metals in Fluvial Sediments of a Rural Catchment: Coxs River, Australia
Effects of direct revegetation on the hydrology, erosion and sediment yield of an abandoned deposit of coal-mine refuse
Performance of some diversity and biotic indices in rivers affected by coal mining in northwestern Spain
Optimum combination of water drainage, water supply and eco-environment protection in coal-accumulated basin of North China
Benthic Invertebrate Population Characteristics as Affected by Water Quality in Coal-Bearing Regions of Tennessee
Evaluation of Coal-Mining Impacts Using Numerical Classification of Benthic Invertebrate Data from Streams Draining a Heavily Mined Basin in Eastern Tennessee
Coal croplines found in the Powder River Basin, 1:24000 scale. Coal cropline is the exposed coal seam due to erosion and tectonics. Each linear feature is attributed with reference to the name of the coal seam that is exposed. The data were originally produced by digitizing photointerpreted coal cropline features off of 1:24,000 USGS quadrangles.
