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.

Choosing the optimal management option requires environmental risk managers and decision makers to evaluate diverse, and not always congruent, needs and interests of multiple stakeholders. Understanding the trade-offs of different options as well as their legal, economic, scientific, and technological implications is critical to performing accurate assessments and making sound decisions. Valuation of Ecological Resources: Integration of Ecology and Socioeconomics in Environmental Decision Making examines various alternatives for determining the “value” of complex ecological resources. The book discusses how ecology, sociology, and economics influence environmental management decisions. The book further explores the scientific underpinnings of ecological valuation and the roles of regulatory and legislative bodies in the decision-making process. A series of case studies demonstrates the utility of various information sets, tools, and analytical frameworks. Summarizes the conclusions reached by the Ecological Risk Assessment Advisory Group during special workshops conducted by the Society of Environmental Toxicology and Chemistry (SETAC) Written by leading experts from industry, academia, and environmental regulatory agencies, this new text is an excellent resource for self-study as well as for courses in industrial ecology, environmental management, ecological risk assessment, environmental policy, and strategies for sustainability and corporate responsibility.

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.

A balanced, comprehensive overview of Environmental Quality Standards (EQS), Derivation and Use of Environmental Quality and Human Health Standards for Chemical Substances in Water and Soil addresses the selection and prioritization of substances for standard derivation. With integrated content and up-to-date information on assessment of regulations that affect the derivation and use of EQS, it examines the derivation of these standards and their implementation to protect human health and the environment. The book is based on contributions from thirty-five scientists, regulators, and policy makers from eleven countries with individual expertise across disciplines such as risk assessment, environmental, health, economic, and social sciences. These scientists summarize current knowledge on aquatic and terrestrial environmental quality standards, placing these standards in a wider socioeconomic and regulatory context. The book explains how to derive environmental standards that are defensible from a scientific and socioeconomic perspective. Using multidisciplinary techniques applicable to water, sediments, and soils; the text demonstrates how to select the best form and derivation method relative to individual environmental standards. The book presents an in-depth examination of when, where, and how to implement environmental standards based on the social and economic context. It includes detailed coverage of technical approaches that shed light on the derivation and implementation of EQSs. It also identifies future research that will help to underpin the science of environmental and human health standards.

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.
