Plutonium and the Rio Grande
Author: William L. GrafPublisher: Oxford University Press, USA
ISBN: 0195089332
Category : Nature
Languages : en
Pages : 346
Book Description
The first atomic bombs were constructed at the Los Alamos National Laboratory, where lab workers disposed of waste plutonium in nearby canyons leading to the Rio Grande. Today, the environmental consequences are just beginning to be understood as scientists examine the effects created by past mishandling of one of the most toxic chemical wastes known. Written in an engaging, accessible style, Plutonium and the Rio Grande is the first book to offer a complete exploration of this environmental history. It includes an explanation of what plutonium is, how much of it was released by the Los Alamos workers, and how much entered the river system directly from waste disposal and indirectly, as a result of atomic bomb fallout. The book includes extensive appendices, maps, diagrams, and photographs. Environmental managers, ecologists, hydrologists and other river specialists, as well as concerned general readers will find the book readable and informative.

Book Description
We often envision the New World before the arrival of the Europeans as a land of pristine natural beauty and undisturbed environments. However, David Lentz offers an alternative view by detailing the impact of native cultures on these ecosystems prior to their contact with Europeans. Drawing on a wide range of experts from the fields of paleoclimatology, historical ecology, paleontology, botany, geology, conservation science, and resource management, this book unlocks the secret of how the Western Hemisphere's indigenous inhabitants influenced and transformed their natural environment. A rare combination of collaborators uncovers the changes that took place in North America, Mexico, Central America, the Andes, and Amazonia. Each section of the book has been comprehensively arranged so that a botanical description of the natural vegetation of the region is coupled with a set of case studies outlining local human influences. From modifications of vegetation, to changes in soil, wildlife, microclimate, hydrology, and the land surface itself, this collection addresses one of the great issues of our time: the human modification of the earth.
