Contaminants of the Great Lakes by Jill Crossman,Chris Weisener Pdf
This book reviews the globally important freshwater resource of the Great Lakes, which is currently threatened by contaminants that compromise water quality and impact its ecological and economic health. Divided into four parts, this volume covers historic, current and emerging sources of contamination from heavy metals and persistent organic pollutants to microplastics; and identifies their ecological impacts. Due to factors ranging from rapidly changing land use practices, climate change and our emerging understanding of their impact on biological, chemical and physical interactions, the effectiveness of management strategies has proven highly variable. Continued enhancements in the rate of lake recovery are required to sustain the health of the Great Lakes. Accordingly, the book also explores recent advances in contaminant detection, along with future steps forward in lake management approaches. Revealing our current knowledge gaps and providing a roadmap towards sustainable solutions, the book offers a valuable asset for scientists, managers and the public alike.
Human Health Risks from Chemical Exposure by R. Warren Flint,John Vena Pdf
More than 100 professionals have contributed to this important book summarizing much of what is known about the issue of chemicals in the Great Lakes environment and the risks these chemicals pose to human health. The book makes significant recommendations for action in policy, communication, education, and research regarding the chemicals and their risks. The views of individuals from government, universities, industries, and public special interest groups in Canada and the United States have been integrated into a comprehensive statement that reflects scenarios that are applicable worldwide.
Persistent Organic Pollutants in the Great Lakes by Ronald A. Hites Pdf
Pollution threatens the Laurentian Great Lakes and is a serious problem. This book examines what is known about the major classes of persistent toxic organic pollutants. Agricultural runoff, urban waste, industrial discharge, landfill leachate, and atmospheric deposition, are all to blame. Contamination of the various ecosystems is reviewed, and what is known about the effects of this pollution. This volume provides an invaluable resource for those in environmental research, measurements, and decision making concerning the Great Lakes.
Trends in Levels and Effects of Persistent Toxic Substances in the Great Lakes by Michael Gilbertson,Glen A. Fox,William W. Bowerman Pdf
`Are the Great Lakes getting better or worse?' This is the question that the public, scientists and managers are asking the International Joint Commission after a quarter-century of cooperative action by the United States and Canadian governments to clean up the Great Lakes. This volume contains papers from the workshop on Environmental Results, hosted in Windsor, Ontario, by the Great Lakes Science Advisory Board of the International Joint Commission, on September 12 and 13, 1996. The Great Lakes have been through almost a century of severe pollution from the manufacture, use and disposal of chemicals. In the 1960s wildlife biologists started to investigate the outbreaks of reproductive failure in fish-eating birds and ranch mink and to link these to exposure to organochlorine compounds. Human health researchers in the 1980s and 1990s linked growth retardation, behavioral anomalies and deficits in cognitive development with maternal consumption of Great Lakes fish prior to pregnancy. The Great Lakes became the laboratory where the theory of endocrine disruptors was first formulated. Now a group of Great Lakes scientists, hosted by the International Joint Commission, has compiled the story of the trends in the concentrations and effects of persistent toxic substances on wildlife and humans. The technical papers review the suitability of various organisms as indicators, and present the results of long-term monitoring of the concentrations and of the incidence of effects. The evidence shows that there was an enormous improvement in the late 1970s, but that in the late 1990s there are still concentrations of some persistent toxic substances that have stubbornly remained at levels that continue to cause toxicological effects.

Restoration of Aquatic Ecosystems by National Research Council,Division on Earth and Life Studies,Commission on Geosciences, Environment and Resources,Committee on Restoration of Aquatic Ecosystems: Science, Technology, and Public Policy Pdf
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
