Download or read book Basin Wildrye Metal Contents in Restored and Unrestored Areas Along Silver Bow Creek and the Upper Clark Fork River written by Anne Marie Morse and published by . This book was released on 2021 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Butte, MT has extensive environmental damage due to 120 years of mining, milling, and smelting starting in the late 1800's with no control or forethought on waste management. The area is now one of the largest superfund complexes in the United States and has been extensively remediated with restoration continuing. A growing number of studies are investigating native plants' ability to aid in metal removal after reclamation efforts. Basin wildrye, Leymus cinereus, grows in each of the restored and contaminated areas sampled. This study investigated the Mn, Fe, Cu, Zn, As, Cd, and Pb content of aerial plants and roots, as well as surrounding soil, on a transect to 25 meters from the creek bank. Aerial plants averaged a content (all values ppm) of Mn 20.0 ℗ł 0.6, Fe 260 ℗ł 67, Cu 4.0 ℗ł 0.2, Zn 30 ℗ł 1, As 0.30 ℗ł 0.01, and Pb 0.200 ℗ł 0.002; roots averaged a content of Mn 104 ℗ł 3, Fe 6,000 ℗ł 2,875, Cu 22.0 ℗ł 0.9, Zn 132 ℗ł 5, As 3.0 ℗ł 0.2, and Pb 4.00 ℗ł 0.04; soils averaged a content of Mn 210 ℗ł 27, Cu 101 ℗ł 4, and Zn 220 ℗ł 16; and cores averaged a content of Mn 270 ℗ł 41, Cu 310 ℗ł 19, Zn 410 ℗ł 39, As 260 ℗ł 56, and Pb 193 ℗ł 6. The soil showed higher metal contents than the roots, which showed higher concentrations than the areal plants. Element content increased with increased distance from the bank. Soil contents increased by factors of 4, 12, and 0.2 for Mn, Cu, and Zn respectively; aerial plant content increased by factors of 0.2, 3, 7, 0.4, and 3 for Mn, Fe, Cu, Zn, and Pb respectively; and root contents increased by factors of 0.2, 58, 10, 0.13, and 9 for Mn, Fe, Cu, Zn, and Pb respectively. In addition, a potential Mn and Fe deficiency below the Warm Springs Settling Ponds could indicate the ponds settle out Mn as well as other metals. Overall, the Warm Springs (contaminated) location had the highest elemental contents followed by Miles Crossing (restored, suspected groundwater upwelling), Santa (twice restored), and Hay Canyon (control). Potentially toxic elements exist in the plants and soil along Silver Bow Creek and the Upper Clark Fork River.

This book was released on 2013-12-01 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem research has emerged in recent decades as a vital, successful, and sometimes controversial approach to environmental science. This book emphasizes the idea that much of the progress in ecosystem research has been driven by the emergence of new environmental problems that could not be addressed by existing approaches. By focusing on successes and limitations of ecosystems studies, the book explores avenues for future ecosystem-level research.

Download or read book Ecological Integrity written by David Pimentel and published by Island Press. This book was released on 2013-04-22 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global Integrity Project has brought together leading scientists and thinkers from around the world to examine the combined problems of threatened and unequal human well-being, degradation of the ecosphere, and unsustainable economies. Based on the proposition that healthy, functioning ecosystems are a necessary prerequisite for both economic security and social justice, the project is built around the concept of ecological integrity and its practical implications for policy and management. Ecological Integrity presents a synthesis and findings of the project. Contributors -- including Robert Goodland, James Karr, Orie Loucks, Jack Manno, William Rees, Mark Sagoff, Robert Ulanowicz, Philippe Crabbe, Laura Westra, David Pimentel, Reed Noss, and others -- examine the key elements of ecological integrity and consider what happens when integrity is lost or compromised. The book: examines historical and philosophical foundations of the concept of ecological integrity explores how integrity can be measured examines the relationships among ecological integrity, human health, and food production looks at economic and ethical issues that need to be considered in protecting ecological integrity offers concrete recommendations for reversing ecological degradation while promoting social and economic justice and welfare . Contributors argue that there is an urgent need for rapid and fundamental change in the ecologically destructive patterns of collective human behavior if society is to survive and thrive in coming decades. Ecological Integrity is a groundbreaking book that integrates environmental science, economics, law, and ethics in problem analysis, synthesis, and solution, and is a vital contribution for anyone concerned with interactions between human and planetary health.
