Concern over the effects of chemicals in the environment has been increasing for many years. Environmental contamination by DDT, Aldrin, Dieldrin, mercury, PCBs, organotins and many other sub stances are all part of the public consciousness and have led to widespread attention to this topic. Some of the concerns have arisen because human health has been affected when contaminants have been consumed via the food chain-for instance in the case of 'Minimata disease' in Japan. In other cases, direct effects on other components of ecosystems have given cause for alarm. The toxic effects which any chemical can cause are a function of exposure and innate toxicity, i.e. of the ability to reach in sufficient quantity a site where a biological process can be disrupted and of the tendency to cause disruption when it gets there. The processes by which chemicals reach sites of toxic action are the subject of this book, and are a fundamental consideration in ecotoxi cology. When a chemical enters the environment e.g. via a spillage or in an effluent, it is potentially subject to a wide variety of processes which may eliminate it from the environment completely, modify it into a more or less harmful substance, or transfer it to another part of the environment. The processes involved are complex and highly variable, but it is essential to increase our understanding of them."

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.

The scope of nanotechnology in medical applications has expanded fast in the last two decades. With their unprecedented material properties, nanoscale materials present with unorthodox opportunities in a wide range of domains, including drug delivery and medical imaging. This book assembles the various facets of nanomedicine while discussing key issues such as physicochemical properties that enhance the appeal of nanomedicine. The book is an excellent resource for physicians, PhDs, and postdocs involved in nanomedicine research to learn and understand the scope and complexity of the subject. It begins with a short history of nanotechnology, followed by a discussion on the fundamental concepts and extraordinary properties of nanoscale materials, and then slowly unfolds into multiple chapters illustrating the uses of various nanomaterials in drug delivery, sensing, and imaging.

Since the dawn of the industrial age, we have unleashed a bewildering number of potentially harmful chemicals. But out of this vast array, how do we identify the actual threats? What does it take to prove that a certain chemical causes cancer? How do we translate academic knowledge of the toxic effects of particular substances into understanding real-world health consequences? The science that answers these questions is toxicology. In The Alchemy of Disease, John Whysner offers an accessible and compelling history of toxicology and its key findings. He details the experiments and discoveries that revealed the causal connections between chemical exposures and diseases. Balancing clear accounts of groundbreaking science with human drama and public-policy relevance, Whysner describes key moments in the development of toxicology and their thorny social and political implications. The book features discussions of toxicological problems past and present, including DDT, cigarettes and other carcinogens, lead poisoning, fossil fuels, chemical warfare, pharmaceuticals-including opioids-and the efficacy of animal testing. Offering valuable insight into the science and politics of crucial public-health concerns, The Alchemy of Disease shows that toxicology's task-pinpointing the chemical cause of an illness-is as compelling as any detective story.

Cutting across traditional subject boundaries, Principles of Ecotoxicology, Fourth Edition gives readers an integrated view of ecotoxicology, from molecules to ecosystems. This new edition of a bestselling textbook continues to emphasize principles rather than practice, providing the interdisciplinary perspective and grounding required for research.

Organized into three sections, the book first describes the molecular structures, properties, and environmental fate of pollutants. It then deals with the effects of pollutants on living organisms at the molecular, cellular, and individual levels. Moving into population biology and population genetics, the third part of the book addresses a question of great interest to ecologists: What effects do pollutants have at the levels of population, community, and the whole ecosystem?

The book also looks at how ecotoxicology is used in the biomonitoring of environmental pollution, the investigation of pollution problems, the conducting of field trials, the study of the development of resistance, and the growing area of environmental risk assessments. Throughout, examples and case studies illustrate the principles.

This updated fourth edition includes new material on nanoparticle pollution, bioaccumulation, biomarkers, and chemical warfare in nature, as well as a new chapter on the future directions of ecotoxicology. A concise textbook that will also appeal to practicing ecotoxicologists, it provides a solid basis for understanding what happens to chemicals in the real world, where they go, how they ultimately degrade, and how they affect the individuals and populations that encounter them.

Since the discovery of Glutathione S-Transferase (GST) or Glutathione transferase, studies have probed important questions about its pharmacological and physiological significance. Toxicology of Glutathione Transferases is the only text that details the methods used in GST research. With chapters written by experts who have been involved in all areas of GST research and have actively contributed to the progress of this field, the book describes the role of GSTs in toxicology, focusing on their pharmacologic and physiologic roles and their relevance to biological toxicology. The book provides current information on gene families, structure and regulation of gene expression, reaction mechanisms and substrates, three-dimensional structures of GSTs, design of proteins with GST activity, and various approaches to developing inhibitors that overcome drug resistance. It also covers the physiological significance and the mechanisms of activation of microsomal GSTs. These topics, along with the role of GSTs in detoxification of chemical carcinogens and possible implications of GST polymorphism in human health and disease, make the volume useful to researchers in the field of pharmacology and toxicology. Chapters cover the possible and exciting role of GSTs in defense mechanisms against chronic oxidative stress-linked disorders such as atherosclerosis and the newly emerging area of GST-mediated modulation of stress-signaling through its catalytic as well as binding activities. They explore an intriguing hypothesis that strongly suggests an important role of the factors that modulate the GSH-electrophile conjugate (GS-E) homeostasis in the regulation of cellular processes. Chapters on known and potential endogenous electrophilic substrates and a major role of GSTs in suppressing stress-induced lipid peroxidation reinforce this newly emerging role of GSTs. These are just a few of the features that make the book helpful to clinicians involved in basic as well as tr

Since the advent of cDNA microarrays, oligonucleotide array technology, and gene chip analysis, genomics has revolutionized the entire field of biomedical research. A byproduct of this revolution, toxicogenomics is a fast-rising star within toxicological analysis. Gathering together leading authors and scientists at the forefront of the field, An Introduction to Toxicogenomics provides a comprehensive overview of this new discipline. With a focus on toxicology, it introduces the basic principles of microarray/oligonucleotide array-based genomic analysis and explains how it fits into the field of biomedical research. These discussions provide an overview to the actual mechanics of the analyses themselves and offer insights on handling and quality control. Then the book features an important section on the basics of data analysis and clustering methods such as genetic algorithms. Finally, it covers the application of expression profiling in the field of toxicology and addresses the two fundamental types of analysis in detail, with sections dedicated to both mechanistic and predictive studies. Although toxicogenomics promises fast, efficient techniques and information-rich data, much of its potential remains untapped. An Introduction to Toxicogenomics consolidates the concepts underlying the field to provide a solid foundation from which to begin your research endeavors.

In spite of the growing importance of Species Sensitivity Distribution models (SSDs) in ecological risk assessments, the conceptual basis, strengths, and weaknesses of using them have not been comprehensively reviewed. This book fills that need. Written by a panel of international experts, Species Sensitivity Distributions in Ecotoxicology reviews the current SSD methods from all angles, compiling for the first time the variety of contemporary applications of SSD-based methods. Beginning with an introduction to SSDs, the chapter authors review the issues surrounding SSDs, synthesizing the positions of advocates and critics with their own analysis of each issue. Finally, they discuss the prospects for future development, paving the way for improved future uses. In sum, this book defines the field of SSD modeling and application. It reveals a lively field, with SSD-applications extending beyond legally adopted quality criteria to other applications such as Life-Cycle Analysis. For anyone developing or revising environmental criteria or standards, this book explores the pros and cons of using the SSD approach. For anyone who needs to apply and interpret SSD-based criteria or standards, the book explains the basis for the numbers, thereby making it possible to correctly apply and defend them. For anyone performing ecological risk assessments, the book covers when and how to use SSDs including alternative assumptions, data treatments, computational methods, and available resources. Species Sensitivity Distributions in Ecotoxicology provides you with a clear picture of these standard models for estimating ecological risks from laboratory toxicity data.

Nutrients are gaining recognition for their role in protecting against the toxic effects of free radicals, alcohol and other substances. At the same time, advances in food technology, the appearance of novel foods and new ingredients have generated new toxicological issues and forced health and safety professionals to develop new and more reliable methods to assess their impact on our health. These issues are at the heart of the second edition of Nutritional Toxicology. The book discusses the role of nutrients in protecting the body against toxicants. It explores the overall importance of the metabolism of xenobiotics and antioxidant nutrients in their increasingly important role in protecting against oxidative damage generated by free radicals. The book also discusses components of the diet that can influence metabolism of drugs, how alcohol consumption affects nutritional status, and conversely, how nutritional status affects alcohol metabolism. The effect of age on the body's ability to metabolize drugs and toxicants is discussed in detail.

We are just beginning to discover the importance of vitamin C in the health of natural and man-made ecosystems. Synthesis of ascorbic acid is well understood, but algae as the only source of ascorbate in the aquatic food pyramid has not been explored. There is an expanding field of the culture of aquatic organisms that demand formulated feeds to best meet their requirements for health, growth, and reproduction. With over 100 species now cultured for human consumption, the question arises as to whether we have reliable information for the dietary needs for vitamin C for even a small percentage of these organisms. A comprehensive approach to the role of vitamin C at the cellular level as well as in the aquatic food chains, this book discusses growth and reproduction, disease resistance, and toxicology of aquatic organisms. Ascorbic Acid in Aquatic Organisms was written as the offshoot of a special session on aquatic organisms and practical aquaculture at the 1998 World Aquaculture Society (WAS) meeting. This book reviews the research already available and identifies new directions for research. It is a unique combination of good nutrition research, ecology, and practical aquaculture (for instance brine shrimp enrichment). This interdisciplinary volume will appeal to marine fish culturists, aquatic biologists, comparative and evolutionary cellular physiologists, and environmental toxicologists.

This volume contains the lectures and seminars given at the NATO Advanced Study Institute on "Sensor Systems for Biological Threads: The Algal Toxins Case," held in Pisa, Italy in October, 2007. The Institute was sponsored and funded by the Scientific Affairs Division of NATO. It is my pleasant duty to thank this institution. This ASI offered updated information on how far the research on algal toxins has gone in the exploration of structures, biosynthesis and regulation of toxins, and the development of technology for bio-monitoring these c- pounds. Algae can form heavy growths in ponds, lakes, reservoirs and sl- moving rivers throughout the world; algae can house toxins which are - ually released into water when the cells rupture or die. Hundreds of toxins have been identified so far. Detection methods, including rapid screening, have been developed to help us learning more about them, especially to find out which toxins are a real threat for people and what conditions encourage their production and accumulation. Early detection of algal toxins is an - portant aspect for public safety and natural environment, and significant efforts are underway to develop effective and reliable tools that can be used for this purpose.

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.

Ecotoxicology of Wild Mammals brings together the latest research on the exposure and effects of environmental contaminants in wild mammal populations.
The underlying theme is encompassed by four questions:

• What exactly do we know about environmental contaminants in wild mammals?
• What are the commonalities and differences between mammal orders/species in the effects that contaminants have?
• How and to what degree of accuracy can we predict the adverse effects of environmental contaminants on mammalian wildlife?
• How significant are contaminant insults compared with other density-independent and -dependent factors such as habitat loss, climatic factors and disease?
