As rising levels of mercury in the environment pose an increasing threat of toxicity to humans and wildlife, several laws already call for industries to reduce mercury emissions at the source. Ecosystem Responses to Mercury Contamination: Indicators of Change outlines the infrastructure and methods needed to measure, monitor, and regulate the concentration of mercury present in the environment. This book draws on the knowledge of forty international experts in the fields of atmospheric transport and deposition, mercury cycling in terrestrial and aquatic ecosystems, and mercury bioaccumulation in aquatic foodwebs and wildlife. The authors propose a set of indicators to use as a measure of changing mercury concentrations in the environment. Next, they recommend a monitoring strategy and offer guidance for determining systematic changes in concentration. Then the authors examine additional monitoring strategies to relate observed changes in concentration to regulatory controls on mercury emissions. The final chapter provides an integrated framework for establishing a national-scale program to monitor mercury concentrations in the environment. Ecosystem Responses to Mercury Contamination: Indicators of Change contains the information needed to design a large-scale monitoring program for mercury and to use the concentration data to create, enforce, and evaluate the progress of initiatives aimed at reducing mercury emissions.

Report on how mercury (Hg) was examined in top-predator fish, bed sediment, and water from streams that spanned regional and national gradients of Hg source strength and other factors thought to influence methylmercury bioaccum. Sampled settings include stream basins that were agr¿l, urbanized, undeveloped, and mined. Predator fish were targeted for collection, and composited samples of fish were analyzed for total Hg (THg), as most of the Hg found in fish tissue is MeHg. Samples of bed sediment and stream water were analyzed for THg, MeHg, and characteristics thought to affect Hg methylation, such as loss-on-ignition and acid-volatile sulfide in bed sediment, and pH, dissolved organic carbon, and dissolved sulfate in water.

Accessibly written by a team of international authors, the Encyclopedia of Environmental Change provides a gateway to the complex facts, concepts, techniques, methodology and philosophy of environmental change. This three-volume set illustrates and examines topics within this dynamic and rapidly changing interdisciplinary field. The encyclopedia includes all of the following aspects of environmental change: Diverse evidence of environmental change, including climate change and changes on land and in the oceans Underlying natural and anthropogenic causes and mechanisms Wide-ranging local, regional and global impacts from the polar regions to the tropics Responses of geo-ecosystems and human-environmental systems in the face of past, present and future environmental change Approaches, methodologies and techniques used for reconstructing, dating, monitoring, modelling, projecting and predicting change Social, economic and political dimensions of environmental issues, environmental conservation and management and environmental policy Over 4,000 entries explore the following key themes and more: Conservation Demographic change Environmental management Environmental policy Environmental security Food security Glaciation Green Revolution Human impact on environment Industrialization Landuse change Military impacts on environment Mining and mining impacts Nuclear energy Pollution Renewable resources Solar energy Sustainability Tourism Trade Water resources Water security Wildlife conservation The comprehensive coverage of terminology includes layers of entries ranging from one-line definitions to short essays, making this an invaluable companion for any student of physical geography, environmental geography or environmental sciences.

"Mercury deposition and contamination is widespread and well documented, and it continues to be a public-health concern for certain sectors of the global human population in both developed and developing countries. This edited volume focuses on integrating the diverse sciences involved in the process of mercury cycling in the environment--from the atmosphere, through terrestrial and aquatic food webs, and human populations--to develop a comprehensive perspective on this important environmental pollutant. Using a systems-level approach, this book provides recommendations on mercury remediation, risk communication, education, and monitoring. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly, expanding into several interdisciplinary fields and encompassing such disparate academic and scientific disciplines as biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists really begun to establish more holistic approaches to studying mercury pollution, giving rise to investigations that have furthered the integration of a multi-tiered approach, especially by using chemistry, biology, and human health sciences collectively. The study of mercury pollution has produced a variety of contributions to domestic and international policies related to the management of mercury in the environment"--Provided by publisher.

This book is a result of the authors’ more than 40 years of study on the behavior, populations, and heavy metals in the colonial waterbirds nesting in Barnegat Bay and the nearby estuaries and bays in the Northeastern United States. From Boston Harbor to the Chesapeake, based on longitudinal studies of colonial waterbirds, it provides a clear picture of the toxic trends and effects of heavy metals in the aquatic environment. The authors take a food web, ecosystem approach to contaminants, using population dynamics, habitat selection, and inputs to the bay to examine metal levels. They also look at the human dimension, discuss what metals in birds tell us about human exposure, and describe stakeholder involvement in these issues. The book covers numbers and dynamics, colony sites and locations, and prey contaminant levels, and compares them to other comparable coastal estuaries. It uses colonial waterbirds as the focal point for an ecosystem approach to metals that begins with prey fish and goes through invertebrates to humans. Additionally, it provides information based on long-term integrative studies the authors have done on metal levels and bird species and compares the findings with data from the Harbor Estuaries Program, other Northeast bays, the Great Lakes, and the Wadden Sea.

Balances Scientific and Economic Points of View to Thoroughly Address Management Issues Responding to the need for clarification and benchmarks, Environmental Life Cycle Costing provides the fundamental basis on which to establish a definitive methodology. Clearly defining environmental LCC, this book balances scientific and economic points of view and thoroughly addresses the management perspective. Demonstrates the Process From Problem Definition to Analysis, to Presentation The book focuses on environmental LCC but also analyzes conventional LCC and societal LCC, providing case studies for each. It presents the link between life cycle costing and life cycle assessment and then explores public, private, and societal options. The book also explains all components of the method using the cross-cutting example of a washing machine. It also provides categorizations that permit the method to be adapted or streamlined as a function of the time available to the practitioner. Case study boxes demonstrate the process for carrying out an LCC, from problem definition to analysis and ultimate presentation to the decision maker. Experts Integrate Conventional Thinking with Emerging Ideas Environmental LCC summarizes all costs associated with the life cycle of a product regardless of who bears those costs. It includes present and future money flows as well as those to be internalized in the decision relevant future. A collaboration of experts at the forefront of research, this book ties conventional thinking on life cycle costs into emerging theory and practice by including environmental and social cost analyses and linking LCC to the environmental and social pillars of sustainability.

One of the major factors behind the writing of the First Edition was the worldwide phenomenon of declining amphibian populations. Although this decline has not abated, the breadth of research into its causes has expanded significantly. This book provides an authoritative compendium of the most recent information.
