As an integral component of environmental policy, it has become essential to regulate and monitor toxic substances. Past emphasis has been primarily on analytical approaches to the detection of specific, targeted contaminants, thus allowing chemical characterisation. However, toxicity testing or biological assessment is necessary for ecotoxicological evaluation, and this offers marked benefits and advantages that complement chemical analysis. Key issues to be addressed include identification of pertinent tests, reproducibility and robustness of these tests, and cost considerations.This book examines these issues and describes and explains the approaches that have been developed for environmental toxicity evaluations. Advantages, benefits and drawbacks of the strategies and methods are highlighted. Directed equally at ecotoxicologists, industrial chemists, analytical chemists and environmental consultants, this book is written in a way that will prove helpful to both new and experienced practitioners.

Developed, developing and emerging economies worldwide are collectively contributing multiple stresses on aquatic ecosystems by the release of numerous contaminants. This in turn demands that basic toxicological information on their potential to harm living species be available. Hence, environmental protection programs aimed at preserving water quality must have access to comprehensive toxicity screening tools and strategies that can be applied reliably and universally. While a good number of toxicity testing procedures and hazard assessment approaches have been published in the scientific literature over the past decades, many are wanting in that insufficient detail is available for users to be able to fully understand the test method or scheme and to be able to reproduce it successfully. Even standardized techniques published in recognized international standard organization documents are often lacking in thoroughness and minutiae. Paucity of information relating to biological test methods may be consequent and trigger several phenomena including generation of invalid data and resulting toxicity measurements, erroneous interpretation and decision-taking with regards to a particular chemical or environmental issue, or simply abandonment of testing procedures. Clearly, improperly documented toxicity testing methods can be detrimental to their promotion and use, as they open the doorway to unnecessary debate and criticism as to their raison d’être. Furthermore, this situation can indirectly contribute to delaying, minimizing or eliminating their application, thereby curtailing the important role toxicity testing plays in the overall protection and conservation of aquatic ecosystems.

Founded on the paradox that all things are poisons and the difference between poison and remedy is quantity, the determination of safe dosage forms the base and focus of modern toxicology. In order to make a sound determination there must be a working knowledge of the biologic mechanisms involved and of the methods employed to define these mechanisms. While the vastness of the field and the rapid accumulation of data may preclude the possibility of absorbing and retaining more than a fraction of the available information, a solid understanding of the underlying principles is essential. Extensively revised and updated with four new chapters and an expanded glossary, this fifth edition of the classic text, Principles and Methods of Toxicology provides comprehensive coverage in a manageable and accessible format. New topics include 'toxicopanomics', plant and animal poisons, information resources, and non-animal testing alternatives. Emphasizing the cornerstones of toxicology-people differ, dose matters, and things change, the book begins with a review of the history of toxicology and followed by an explanation of basic toxicological principles, agents that cause toxicity, target organ toxicity, and toxicological testing methods including many of the test protocols required to meet regulatory needs worldwide. The book examines each method or procedure from the standpoint of technique and interpretation of data and discusses problems and pitfalls that may be associated with each. The addition of several new authors allow for a broader and more diverse treatment of the ever-changing and expanding field of toxicology. Maintaining the high-quality information and organizational framework that made the previous editions so successful, Principles and Methods of Toxicology, Fifth Edition continues to be a valuable resource for the advanced practitioner as well as the new disciple of toxicology.

Chemical Warfare in Nature Pesticides and other industrial chemicals are at the root of many pollution problems. In view of the toxic effects of industrial chemicals found in the water, soil, and air, Ecotoxicology: Effects of Pollutants on the Natural Environment considers the impact of chemicals on the environment from a wider perspective: the evolution of plant toxins—and defense mechanisms against them in animals as a consequence of plant–animal warfare. Comparisons are made between this and the development of resistance by insects towards man-made insecticides. Pesticides and Drugs The text focuses particularly on problems posed by pesticides and, to a lesser extent, by drugs. This material specifically addresses the problems that pesticides pose and explores the development of resistance to them. It focuses on the history of pesticides, pesticide selectivity between target species and beneficial organisms, and types of pesticides. It discusses mandatory ecotoxicity testing as part of the process of risk assessment of environmental chemicals. The text considers the effects of pollutants at the population level, with respect to changes in numbers and genetic composition. It factors in the sublethal effects of pollutants on population levels, and cites an increase in the concentration of persistent pollutants in natural food chains as a cause of the decline of certain vertebrate predators. Overall the text: • Considers plant toxins as models for pesticides • Emphasizes principles illustrated with practical examples • Includes a glossary of terms Divided into three sections, this text uses a variety of examples and case studies to examine the effects of pollutants—including naturally occurring ones—on natural processes. It guides the reader through the basic issues and principles; outlines the science of ecotoxicology, which is the study of the effects of chemicals upon ecosystems; and introduces various strategies for pollution control.

Annotation This book describes the different tests that must be performed on new chemicals and other materials to demonstrate to the regulatory authorities that they are safe for use. Tests vary from physico-chemical, measuring properties such as melting point and density, through genetic toxicity studies, to mammalian toxicology and studies to investigate effects on the environment. This book describes clearly the process of obtaining approval for use in a variety of global regions and across different applications. It also explains why different tests are performed and the implications of the results.
