The Earth’s oceans are currently undergoing unprecedented changes: rivers have suffered a severe reduction in their sediment transport, and as a result, sediment input to the oceans has dropped lower than ever before. These inputs have varied over millennia as a result of both natural occurrences and human actions, such as the building of dams and the extraction of materials from riverbeds. Sedimentary Crisis at the Global Scale 1 examines how river basins have been affected by the sedimentary crises of various historical epochs. By studying global balances, it provides insights into the profound disruption of the solid transport of fluvial bodies. The book also explores studies of various rivers, from the Amazon, which remains relatively unaffected, to dying rivers such as the Colorado and the Nile.
Copper has been mined and processed at the Mount Lyell mine at Queenstown in western Tasmania for a century but it was not until Copper Mines of Tasmania took the Mount Lyell mine over in 1994 that more than scant regard was paid to protecting the ennvironment. Historically, the mine was a economic focal point for western Tasmanian development, with towns, railways and governments all dependent on its fate. But the environmental impact and costs of this prosperity were high. With ' new' industries on the west coast such as ecotourism and aquaculture, which depend on a 'clean' environment, the existing and continuing pollution from historic mining practices does not meed the present expectati...
The purpose of this report is to describe laboratory analytical methods for the determination of pesticides and selected organic compounds in the dissolved phase of the water column and to provide a single document containing a listing of all concentrations and graphs of mass transport of pesticides and organic contaminants in the Mississippi River and some of its tributaries.
