Carbon Isotope Techniques deals with the use of carbon isotopes in studies of plant, soil, and aquatic biology. Topics covered include photosynthesis/translocation studies in terrestrial ecosystems; carbon relationships of plant-microbial symbioses; microbe/plant/soil interactions; and environmental and aquatic toxicology. Stable carbon isotope ratios of natural materials are also considered. Comprised of 15 chapters, this book begins with an introduction to radiation-counting instruments used in measuring the radioactivity in soil and plant samples containing carbon-14. The discussion then turns to the basic methods of 14C use in plant science, highlighted by three examples of applications in the field of plant physiology and ecology. Subsequent chapters explore the use of carbon isotope techniques for analyzing the carbon relationships of plant-microbial symbioses; the interactions of microbes, plants, and soils; and the degradation of herbicides and organic xenobiotics. Carbon dating and bomb carbon are also described. The final section is devoted to the uses and procedures for 13C and 11C. This monograph is intended for advanced undergraduate or graduate students, as well as generalist scientists who have not previously used radioisotopes or stable isotopes in their research.

This CD-ROM provides the facts, abstracts and figures needed to build environmental models together with information on the environmental effects of chemical substances. The data has been rigorously selected from scientific journals covering 25 years. Environmental models included cover a wide range of topics, including eutrophication, dispersion of chemical compounds, growth and competition of different organisms as well as models which describe global environmental cycles.Ecotoxicological information on substances includes the water concentrations at which aquatic organisms are affected by the chemical compounds. These concentrations are used in the regulation of releases and for calculating safe concentration levels in the environment. The growth of environmental toxicological data and the growth of different types of environmental models has been a major new development in this field.ECOTOX: Ecological Modelling and Ecotoxicology presents ecotoxicological information about more than 2000 chemical substances, including such data as growth parameters, lethal concentrations (LC50), emissions, degradation of chemical substances, background concentrations, concentration factors, biological effects, octanol/water partition coefficients, excretion and uptake rates, emissions and composition of living organisms. Accompanying this information are the constants and equations to be used in environmental models, and abstracts from scientific journals to give an explanation concerning the scope of the data.All this information is directed towards environmental modelling, administration of environmental regulations, scientific models, environmental policy making and environmental impact assessment.NEW FROM APRIL 2001 - http://www.enviromod.subnet.dk/Ecological and Environmental Modeling - An Interactive Internet Course

Volume III addresses our present understanding of how oxidation is involved both positively and negatively in life processes. This is a more recent and rapidly developing aspect of oxidation chemistry and many of the concepts still have to be proved by rigorous scientific investigation. Nevertheless, the mechanistic principles developed as a result of studies in vitro over the years now provide the basis for understanding the complex oxidation chemistry of life processes and its control by biological antioxidants.

Many years have passed since the last edition of the present book was published. The discovery during this period of many new reagents has resulted in a vast accumulation of data on their application and made this completely revised edition necessary.Numerous new tests and various new chapters have been added. Chapters 3,4 and 5 of the fifth edition have been combined into one chapter, which is divided into sections devoted to the elements. These sections are arranged in alphabetical order to make for easier location of information on a given element. To further improve the usefulness of the volume, a reference list has been provided for each sub-section followed by a biography of the appropriate quantitative methods.

Tropical Radioecology

Tropical Radioecology is a guide to the wide range of scientific practices and principles of this multidisciplinary field. It brings together past and present studies in the tropical and sub-tropical areas of the planet, highlighting the unique aspects of tropical systems. Until recently, radioecological models for tropical environments have depended upon data derived from temperate environments, despite the differences of these regions in terms of biota and abiotic conditions. Since radioactivity can be used to trace environmental processes in humans and other biota, this book offers examples of studies in which radiotracers have been used to assess biokinetics in tropical biota.

The first purpose of this book is to provide a comprehensive review of the state of development of natural analogue studies with emphasis on those studies which are relevant to the following repository designs: Nagra (Switzerland) disposal concepts for high-level waste/low and intermediate-level waste; SKB (Sweden) disposal concepts for spent fuel/low and intermediate-level waste; and Nirex (UK) disposal concept for low and intermediate-level waste.The book's second aim is to discuss the expanding application of natural analogues for non-performance assessment purposes, especially their potential for presenting the concept of geological disposal to various interested audiences in a coherent, understandable and scientifically legitimate manner.Much of the discussion of the book is relevant to concepts for geological disposal of radioactive wastes by other countries, and is concerned only with those physico-chemical processes which control the release of radionuclides from the near-field, and their subsequent retardation and transport in the geosphere.

Lead and Public Health

The book presents a detailed assessment of the health science of lead and the human health risk assessment models for lead’s human health impacts, followed by an account of various regulatory efforts in the United States and elsewhere to eliminate or reduce human toxic exposures to lead. The science of lead as presented here covers releases of lead into the environment, lead’s movement through the environment to reach humans who are then exposed, and the spectrum of toxic effects, particularly low-level toxic effects, on the developing central nervous system of the very young child. The section on human health risk assessment deals with quantifying not only the dose-response relationships that underlie toxic responses to lead in sensitive populations but also with the likelihood of toxic responses vis-à-vis environmental lead at some level of exposure. This section includes a treatment of computer models of lead exposure, particularly those that use lead in whole blood as a key measure. Various models convert lead intake via various body compartments into measures of body lead burden. Such measures are then directly related to severity of injury. The final section of the book deals with past and present regulatory efforts to control lead releases into the human environment. Current control efforts present a mixed picture. The most problematic issue is the continued presence of lead paint in older housing and lead in soils of urban and mining industry communities.

Key Concepts in Environmental Chemistry provides a modern and concise introduction to environmental chemistry principles and the dynamic nature of environmental systems. It offers an intense, one-semester examination of selected concepts encountered in this field of study and provides integrated tools in explaining complex chemical problems of environmental importance. Principles typically covered in more comprehensive textbooks are well integrated into general chapter topics and application areas. The goal of this textbook is to provide students with a valuable resource for learning the basic concepts of environmental chemistry from an easy to follow, condensed, application and inquiry-based perspective. Additional statistical, sampling, modeling and data analysis concepts and exercises will be introduced for greater understanding of the underlying processes of complex environmental systems and fundamental chemical principles. Each chapter will have problem-oriented exercises (with examples throughout the body of the chapter) that stress the important concepts covered and research applications/case studies from experts in the field. Research applications will be directly tied to theoretical concepts covered in the chapter. Overall, this text provides a condensed and integrated tool for student learning and covers key concepts in the rapidly developing field of environmental chemistry.
