Assessing The Toxicity Of A Reconstituted Water Simulating Streams Influenced By Mountaintop Mining In Central Appalachia, Benjamin David Browning
Assessing The Toxicity Of A Reconstituted Water Simulating Streams Influenced By Mountaintop Mining In Central Appalachia, Benjamin David Browning
Theses, Dissertations and Capstones
Freshwater ecosystems in Central Appalachia experience increased concentrations of manganese (Mn) and total dissolved solids from the runoff of surface mines and valley fills. Biological communities have been impacted by these surface mining operations and it has been suggested that the increase in total dissolved solids may contribute to these negative effects, but standard laboratory toxicity tests have not found increased concentrations of total dissolved solids to have such negative effects as seen in the field. The elevated total dissolved solids in mining influenced streams may only be toxic in conjunction with another toxicant that is presence in these systems …
