Wildlife Toxicity Assessments for Chemicals of Military Concern is a compendium of chemical-specific toxicity information with discussions on the rationale and development of Wildlife Toxicity Reference Values (TRVs) intended for use on terrestrial wildlife for risk assessment applications. Substances covered include military-related chemicals including explosives, propellants, pesticides and metals.
Wildlife Toxicity Assessments for Chemicals of Military Concern is a much-needed resource designed to meet the needs of those seeking toxicological information for ecological risk assessment purposes. Each chapter targets a specific chemical and considers the current knowledge of the toxicological impacts of chemicals to terrestrial wildlife including mammalian, avian, amphibian and reptilian species.
Provides detailed information on how Wildlife Toxicity Values (TRVs) for military chemicals of concern are derived and evaluated. Covers wildlife toxicity assessments of explosives, metals and environmental chemicals. Compiles relevant information on the environmental effects of chemicals on wildlife in relation to public and environmental health.

Understanding Risk to Wildlife from Exposures to Per- and Polyfluorinated Alkyl Substances (PFAS) provides the most recent summary of toxicity data relevant to mammals, birds, reptiles, and amphibians, and provides values for use in risk assessment applications. Predicting the bioaccumulation of PFAS in terrestrial wildlife (including humans) has proven to be extremely complex. As a group, PFAS act differently than traditional non-ionic organic molecules, where PFAS can break down and reform, whereas some are demonstrated to be extremely persistent. Where sufficient data are provided, this book establishes toxicity reference values (TRVs), which are derived to assist in characterizing environmental sources of contamination and making risk-based decisions.Features: Provides toxicity reference values (TRVs) for vertebrates (mammals, birds, amphibians) for PFAS, where sufficient data are available, and includes objective supporting background information. Assigns a level of confidence to each TRV to provide the risk assessor with an understanding of the relative uncertainty associated with each value. Presents toxicity data in the formats of scatter diagrams and tables for quick review and assessment. Provides TRVs relevant for screening and decision makingThis book serves as a useful aid for risk assessors and managers in those industries that have sites contaminated with PFAS, consultants tasked with evaluating risks at such sites, and staff at regulatory agencies at various governmental levels, who need to know how much contamination is considered safe for wildlife. It will also appeal to researchers with an interest in filling the gaps in the current toxicological data for PFAS exposure.

Education in World History shows how broad currents in transnational history have interacted with trends in educational organization and teaching practices over time.From antiquity and early classical societies to present day, this book highlights the ways in which changes in religious and intellectual life and economic patterns in key world regions have generated developments in education. Since the postclassical period, cross-cultural connections have also influenced educational change. In more recent times, transnational dialogues and mobility have played a vital role in shaping educational patterns. Ranging through South and East Asia, Africa, Europe and the Americas, the book also considers how the impact of modern forces, such as industrialization and nationalism, have transformed education in fundamental ways. Throughout the volume, Mark S. Johnson and Peter N. Stearns emphasize the tensions between elite and state educational interests and more diverse popular demands for access and, often, for more innovative pedagogy.Suitable for introductory world history and history of education courses, this lively overview reconsiders the history of education from the perspective of world and comparative history.

Provides a hands-on approach to demilitarization and environmental aspects of energetic materials and munitions This book gives an overview of the environmental impact of the production, use, and cleanup of energetic materials and munitions. It provides scientists, engineers, environmental specialists, and users with the understanding of environmental issues for munitions and of the ways to improve design and manage potential risks. It covers the various aspects of how chemical properties influence fate, transport, and toxicity of new formulations and prescribes tools for reducing or alleviating environmental risks. In addition, it discusses pyrotechnics and the problem of dealing with munitions underwater. Chapters in Energetic Materials and Munitions: Life Cycle Management, Environmental Impact and Demilitarization look at demilitarization in general, as well as in the future. Topics covered include logistics, costs, and management; life cycle analysis and management; and greener munitions. Another introduces readers to the "One Health" approach in the design of sustainable munition compounds. Following that, readers are taught about land assessment for munitions-related contamination in military live-fire training. The book also examines the development and integration of environmental, safety, and occupational health information. -Brings together in one source expertise and in-depth information on the current and future state of how we handle the production, use, and demilitarization of explosives and weaponry -A handy reference for experienced practitioners, as well as for training young professionals in the field -Every chapter contains real-life examples and proposes future directions for the field Energetic Materials and Munitions: Life Cycle Management, Environmental Impact and Demilitarization is an important book for explosives specialists, pyrotechnicians, materials scientists, military authorities, safety officers, health officers, and chemical engineers.
