    Final Report of the Dutch Priority Programme on Acidification
    • 1 Edición
    • Volumen 46
    • T. Schneider + 1 más
    • Inglés
    This book contains the results and conclusions of extensive research on the causes and effects of acidification of forests/forest soils and heathland in the Netherlands. In 1985 the Dutch Priority Programme on Acidification was started in order to give a more concrete form to the increasing interest of policy-makers in the effects of air pollution on ecosystems in particular.In the last three years, the research has focused on obtaining a more accurate estimate of the emission of ammonia on the deposition of SOx, NOy and NHx, and also on quantifying effects on forest and heathland ecosystems. This quantification of effects included experimental work model analyses, and derivation of critical loads and levels for forest and heathland ecosystems. Furthermore, scenario analyses were made with the Dutch Acidification Systems Model (DAS) in order to evaluate the effectiveness of policy measures.The research itself, which formed the basis for this book, has been described in the reports on individual projects. A summary of the scientific results and conclusions is given in thematic reports (added as annex). An independent Review Team has provided a critical assessment of the research carried out since 1988. The Review Report has been incorporated as annex.

  • Dynamic Aquaria

    Building Living Ecosystems
    • 1 Edición
    • Walter H. Adey + 1 más
    • Inglés
    Dynamic Aquaria is the outgrowth of years of research aimed at studying how to accurately model and construct living ecosystems in mesocosms, microcosms, and aquaria. It is a unique book, presenting scientifically sound information for a growing new area of science--synthetic ecology, or the construction of living ecosystems. At the same time, the authors present thoughtful perspectives on how knowledge gained by creating these smaller ecosystems helps us to understand our wild ecosystems and biosphere as a whole.

This is a synthetic compilation of well-established techniques.Researche... and students in a wide range of disciplines spanning plant and soil science, agricultural chemistry, forestry, ecology, oceanography, limnology, biogeochemistry, anthropology, and archaeology will find Carbon Isotope Techniques a valuable resource.

  • Advances in Ecological Research

    • 1 Edición
    • Volumen 21
    • Inglés
    This volume contains five papers dealing with a wide range of plant, animal, and soil biological topics.Gray and his colleagues describe the origin and spread of the salt marsh grass Spartina anglica. The result of a hybridization at the close of the last century, this genetically uniform species has been extremely successful in its particular niche and has a fascinating biology.Smith stresses the importance of gene-environment interactions in life-history theory in contrast to the resource constraint emphasis of the optimization approach. Experimental approaches to the subject are also discussed.Chanway and his colleagues examine the evidence for the importance of interactions between plants and micro-organisms in the rhizosphere in determining the outcome of plant competition and the establishment of community structure. Despite scarce evidence, real effects meriting further research do seem to exist.Brundrett also deals with an aspect of ecology in the soil. Most plants seem to have mycorrhizal associates and their importance is now widely appreciated. Much has been learned but more research is needed to determine the beneficial or after effects of mycorrhizae in natural systems.Richter and Babar review the diversity of tropical soils. They are in fact much more variable than is often thought, perhaps because too few ecologists are specialists in soils. Clearly, a proper knowledge and understanding of the many soil types is vital to conservation and development work in the tropics.

  • Environmental Biotechnology

    • 1 Edición
    • Volumen 42
    • A. Blažej + 1 más
    • Inglés
    The growing awareness of environmental problems provided the stimulus for this 4th International Symposium on Biotechnology, Interbiotech '90, to address many aspects of the relationship between biotechnology and the environment. The papers are mainly devoted to the contribution of biotechnology in solving environmental problems, including biological waste water treatment, utilization of municipal sewage sludge, detoxification of polluted soil and complex utilization of lignocellulosic wastes. There is examination of possible dangers in such cases as the release of r-DNA organisms into the environment. The relationship of biotechnology and energy (e.g. biogas, landfill gas fuel, photosynthetic systems for fuel production) is also discussed.

  • Receptor Modeling for Air Quality Management

    • 1 Edición
    • Volumen 7
    • P.K. Hopke
    • Inglés
    This book presents the background and application of receptor models for the source identification and quantitative mass apportionment of airborne pollutants. Over the past decade, receptor models have become an accepted part of the process for developing effective and efficient air quality management plans. Information is provided on the ambient and source sampling and chemical analysis needed to provide the input data for receptor models. Commonly used models are described with examples so that the air quality specialist can see how these models are applied. Recent advances in several areas of the field are presented as well as the perspective of both U.S. Federal and State level air quality managers on how these models fit into the development of a management plan.The aim of the book is to provide a practical guide to persons who may be given the task of implementing receptor modeling as a part of some air quality management problem. The intention of all the chapter authors is to furnish both the basic information needed to begin doing receptor modeling as well as some insight into some of the problems related to the use of these models. These tools like any others used in solving complex technological problems are not a panacea, but do represent powerful aids in data analysis that can lead to insights as to how an airshed functions and thus, to effective and efficient air quality management strategies.

  • Applied Isotope Hydrogeology

    A Case Study in Northern Switzerland
    • 1 Edición
    • Volumen 43
    • F.J. Pearson + 7 más
    • Inglés
    In 1980, Nagra, the Swiss National Cooperative for the Storage of Radioactive Waste, began a comprehensive field investigation programme to assess the feasibility and safety of a repository for the final disposal of high-level radioactive waste in northern Switzerland. An international team of scientists has carried out a comprehensive study on the isotope hydrogeology of deep groundwaters. One of the major implications of this work pertains to the storage of radioactive waste. The study goes far beyond an in-depth regional study as it draws together the results of diverse techniques, many of which have been re-evaluated or further developed.This book presents in great detail the results of one of the most comprehensive isotope hydrology studies ever undertaken.

  • Evaluation of Environmental Data for Regulatory and Impact Assessment

    • 1 Edición
    • Volumen 41
    • S. Ramamoorthy + 1 más
    • Inglés
    Mounting concern for the state of the environment has led to a substantial increase in the collection of environmental data in the past two decades. This trend raises issues with regard to the quality assurance and quality control of the data gathering process, from sampling to analysis. The evaluation of environmental data in terms of quality, and relevance for use in the management of toxic chemicals in the enviroment, has reached a critical phase. An enormous volume of data is being generated, on both residue levels and their effects, to meet short- and long-term needs for regulatory procedures and (environmental) impact assessments. Therefore, it is important to verify not only the quality of the data collected, but also the choice of relevant test parameters. This volume deals with the evolution of analytical methodologies to the current state-of-the-art techniques, quality assurance/quality control of data acquirements, and testing procedures for screening of toxic chemicals - including their hazard identification, persistence, and fate processes in the environment. The models currently employed in environmental impact assessment and risk assessment are also discussed in detail. Public involvement and participation in regulatory decision-making processess is also described. It is intended for managers and scientists involved in environmental management and research of toxic chemicals in the environment.
