Projected emissions of sulfur and nitrogen are expected to have continuing negative impacts on forests, in spite of reductions in sulfur emissions as a result of SO2 control programs. Sulfur and nitrogen emissions present serious long-term threats to forest health and productivity in the United States. This report is intended to explain the differences in approaches for calculating critical loads for forest ecosystems in Europe, Canada, and the United States; it is directed to air quality regulators and Federal Land Managers (FLMs) in the United States, and addresses concerns particular to U.S. Federal lands. The paper describes the basic mass balance approach for calculating critical loads, presents the various critical thresholds, and explains the assumptions inherent in the calculation and data selection procedure. The input necessary from FLMs in the process of estimating the critical load is described.

This book provides a unique overview of research methods over the past 25 years assessing critical loads and temporal effects of the deposition of air pollutants. It includes critical load methods and applications addressing acidification, eutrophication and heavy metal pollution of terrestrial and aquatic ecosystems. Applications include examples for each air pollution threat, both at local and regional scale, including Europe, Asia, Canada and the US. The book starts with background information on the effects of the deposition of sulphur, nitrogen and heavy metals and geochemical and biological indicators for risk assessments. The use of those indicators is then illustrated in the assessment of critical loads and their exceedances and in the temporal assessment of air pollution risks. It also includes the most recent developments of assessing critical loads and current and future risks of soil and water chemistry and biodiversity under climate change, with a special focus on nitrogen. The book thus provides a complete overview of the knowledge that is currently used for the scientific support of policies in the field of air pollution control to protect ecosystem services.

Ecotoxicology offers an overview of current ecotoxicological problems. It includes basic ecotoxicological concepts, as well as information about chemicals and toxic substances that may cause harmful effects on the ecosystem and its living components. The book, with a total of 48 chapters, is divided into three parts. The first part includes the basic concepts of ecotoxicology, starting with an introductory chapter on ecotoxicology as a subdiscipline of ecology; assessment on ecotoxicological effects and risk; and properties and effects of toxic chemicals. These topics are further discussed throughout the book, along with nomenclature, focal topics, and the history of ecotoxicology. The two remaining parts tackle harmful properties and harmful chemicals. The second part also covers bioaccumulation, bioavailability, biodegradability, biodegradation, and biomagnification. It also provides models for ecotoxicological populations, ecosystems and landscapes, and on food-web bioaccumulation. Chemicals including benzene, copper, lead, nitrogen, phenols, pheromones, phthalates, plutonium, and uranium are covered in separate chapters in the final part. This book will be of great value to ecologists, ecotoxicologists, and environmental managers. - Provides an overview of the theory and application of global ecology - International focus and range of ecosystems makes Ecotoxicology an indispensable resource to scientists - Based on the bestselling Encyclopedia of Ecology - Full-color figures and tables support the text and aid in understanding

This book is aimed at generalizing the modern ideas of both biogeochemical and environmental risk assessment that have been developed in recent years. Only a few books are available in this interdisciplinary area, since most deal mainly with various technical aspects of ERA description and calculations. This text aims at supplementing the existing books by providing a modern understanding of mechanisms responsible for ecological risks for human beings and ecosystems.

In this book is summarized those management principles that should be valid in areas where forests continuously are used for production, where biodiversity aspects are important as well as economy and productivity, and where demands on soil status and water quality are set. Especially the very long-term aspects are emphasized, and it is shown how system model thinking is used to reach the goals. Biogeochemical aspects are put forward as they are very important in areas on poor bedrock with acid soils. Forest vitality and stress on trees are treated, as well as the importance of wildlife and their effects of browsing. The balance between social and recreational demands from the society and the economical needs of the landowner is of great concern. Experiences from a special area in South Sweden are presented.

The subject of acid deposition remains one of the most urgent of our contemporary environmental problems. Research programmes are continually redefming our understanding of cause and effect and hence the continuing need for a timely and authoritative series addressing these issues. This volume seeks to review and defme our contemporary understanding of acid deposition by reference to new international data and as a consequence assist the definition of our future research requirements and policy developments. International contributions to the volume are drawn from the Federal Republic of Germany, the U.S.A., Canada, Brazil, Switzerland, Austria, Israel, France and the United Kingdom. Some of these nations have experienced acid deposition on a regional scale for considerable periods of time; for others the phenomenon is an emerging problem. This collection of papers has been compiled by invitation to eminent members of the acid deposition research community and by selection from a carefully targeted call for papers. It is primarily designed to meet the needs of researchers, lecturers and postgraduate students in environmental disciplines and for environmental policy makers. It is of interest to professionals in related disciplines and essential as a reference text for libraries. The volume is divided into four broad themes: Emissions, chemistry and deposition; Ecosystem effects (freshwater, soils and forest systems); Effects on structural materials; Mitigation, control and management. Each of these sections provides an overview of contemporary understanding, presents new experimental or field evidence and provides guidance for our future research agenda.

The management of air quality is currently at the forefront of international debate. With authors drawn from international experts in their respective fields, Air Quality Management provides comprehensive coverage of the air quality management issue. There are chapters on improving air quality in the UK, the construction of emissions inventories and the design and operation of air monitoring networks. Validation of air pollution models, requiring source receptor modelling, is described, as is the use of geochemical or biological tolerances known as critical loads to determine the maximum allowable inputs of pollutants to the terrestrial environment. The first European Auto-Oil Study, which was sponsored by the European Commission in order to identify the most cost-effective means of meeting air quality targets, is included as a case study. There is also reference to the successes and problems of air pollution control in California, the US state which has pioneered the promotion of vigorous air pollution control measures. Air Quality Management provides a vital source of material for all those involved in the field, whether as a student, industrialist, consultant, or government agency with responsibility in this area.
