This useful guide contains more than 3,000 environmental acronyms and abbreviations. It also includes a glossary of more than 1,000 environmental terms for those frequently used but difficult to find expressions, written in non-technical, easy-to-understand language.

To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

Defines in non-technical language the more commonly used environmental terms appearing in EPA pub's., news releases, & other Agency documents. The definitions do not constitute the Agency's official use of terms for regulatory purposes; official terminology may be found in the laws & related regulations as published in such sources as the Congressional Record, Federal Register, & elsewhere. These terms are derived from previously published lists, internal glossaries produced by various programs & specific suggestions made by personnel in many Agency offices. The chemicals & pesticides selected for inclusion are limited to those most frequently referred to in Agency pub's. or that are the subject of major regulatory or program activities.

Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Chemicals contains a detailed and comprehensive methodology for developing acute exposure guideline levels (AEGLs) for toxic substances from inhalation exposures. The book provides guidance on what documents and databases to use, toxicity endpoints that need to be evaluated, dosimetry corrections from animal to human exposures, selection of appropriate uncertainty factors to address the variability between animals and humans and within the human population, selection of modifying factors to address data deficiencies, time scaling, and quantitative cancer risk assessment. It also contains an example of a summary of a technical support document and an example of AEGL derivation. This book will be useful to persons in the derivation of levels from other exposure routesâ€"both oral and dermalâ€"as well as risk assessors in the government, academe, and private industry.

Provides definitions of a wide variety of acronyms, initialisms, abbreviations and similar contractions, translating them into their full names or meanings. Terms from subject areas such as associations, education, the Internet, medicine and others are included.

It is increasingly vital that students of international relations and international law, diplomats and other negotiators and observers understand the conditions and realities within which global policy-making, including that relating to the environment, is undertaken. Thought-provoking yet hopeful, the ideas put forward in this book provide students, practitioners, policy-makers and experts with an essential handbook and guide to the field of Global Environmental Governance (GEG). It contains a comprehensive glossary of terms and a substantial list of acronyms, and also incorporates a compelling essay, challenging those concerned with the management of our planet and its inhabitants to understand and accept a vocabulary common to the often opposing GEG objectives which have emerged in the last fifty years.

Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.
