People use lots of water for drinking, cooking and washing, but significantly more for producing things such as food, paper and cotton clothes. The water footprint is an indicator of water use that looks at both direct and indirect water use of a consumer or producer. Indirect use refers to the 'virtual water' embedded in tradable goods and commodities, such as cereals, sugar or cotton. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business. This book offers a complete and up-to-date overview of the global standard on water footprint assessment as developed by the Water Footprint Network. More specifically it: o Provides a comprehensive set of methods for water footprint assessment o Shows how water footprints can be calculated for individual processes and products, as well as for consumers, nations and businesses o Contains detailed worked examples of how to calculate green, blue and grey water footprints o Describes how to assess the sustainability of the aggregated water footprint within a river basin or the water footprint of a specific product o Includes an extensive library of possible measures that can contribute to water footprint reduction

After fifteen years and three editions, Introduction to Environmental Toxicology: Molecular Substructures to Ecological Landscapes has become a standard that defines the field of environmental toxicology, and the fourth edition is no exception. The authors take an integrated approach to environmental toxicology that emphasizes scale and context as important factors in understanding effects and management options. New in the Fourth Edition: New author, Dr. Ruth M. Sofield 8-page color insert New chapter on fate and transport of contaminants Emphasis on the use of all types of models in understanding how nature works Revised sections on synergy and atrazine toxicity Updated coverage of the analysis of impacts to populations, communities and ecosystems Enlarged risk assessment chapter with an in-depth description of a regional scale risk assessment This edition benefits from the insight of a new author, Dr. Ruth M. Sofield, who prepared the new chapter on the fate and transport of contaminants. The relationship between structure and toxicological properties has been a major theme of this book since its inception and this new chapter expands this fundamental concept to include fate and transport. In the early chapters the use of models in science is discussed and this theme carries throughout the rest of the book. So much has changed in the fifteen years since the publication of the first edition. The mid-1990s seem so long ago, when our understanding of environmental toxicology was very basic. Ecological risk assessment was in its very early stages and the consideration of the effects of toxicants on landscapes was only beginning. Computation was still hard, genes stayed put, and it was only becoming recognized that xenobiotics could have hormonal effects — developments that are taken for granted in this edition. Written by authors who teach this subject, a feature that is reflected in their straightforward style, the book provides a foundation for understanding environmental toxicology and its application.

"Intended for those with an understanding of the current regulatory framework, the book sets out the basic numerical application of the International Financial Accounting Standards and includes. A thorough introduction to the accounting standard-setting process; A guide to the boards, committees and councils responsible for the standards; Detailed coverage of individual standards, including Asset Valuation, Liabilities and Group Reporting; and Published accounts of well known British and European companies."--BOOK JACKET.

This book de-mystifies the jargon of webcams and computer processing, and provides detailed hints and tips for imaging the Sun, Moon and planets with a webcam. It demonstrates how inexpensive tools are revolutionizing imaging in amateur astronomy. Anyone with a modest telescope and a webcam can now obtain jaw-dropping lunar and planetary images to rival those taken with mid-range astronomical CCD cameras costing thousands of dollars. A glance through the images in this book shows just what spectacular results can be achieved by using a webcam with your telescope! Your scientific results will be sought by professional astronomers.
