Environmental Toxicology is a comprehensive introductory textbook dealing with most aspects of the subject, from the molecular to the ecosystem level. Early chapters deal with basic and advanced concepts, methods and approaches. The next tier discusses the environmental toxicology of individual or groups of substances. The third part addresses complex issues, in which many of the concepts, approaches and substances covered in earlier tiers are incorporated. The fourth part includes chapters on risk assessment, rehabilitation and regulatory toxicology. The book concludes with a summary of present and future areas of emphasis. Each chapter contains a comprehensive list of references and further reading, case studies from different jurisdictions, and student exercises. Environmental Toxicology is primarily a textbook for undergraduate and graduate students in environmental toxicology, environmental chemistry, ecotoxicology, applied ecology, environmental management, and risk assessment. It will also be valuable for specialists in ecology, environmental science, and chemistry.

The book contains the contributions at the NATO Study Institute on Exposure and Risk Assessment of Chemical Pollution – Contemporary Methodology, which took place in Sofia – Borovetz, Bulgaria, July 1–10, 2008. Rapid advances in mathematics, computer science and molecular biology and chemistry have lead to the development in of a new branch of toxicology called Computational Toxicology. This emerging field is addressing the estimation and prediction of exposure risk and effects of chemicals based on experimental data, measured concentration and biological mechanisms and computational models of biological systems. Mathematical models are also being used to predict the fate and transport of substances in the environment. Because this area is still in its infancy, there has been limited application from governmental agencies to regulating controllable processes, such as registration of new chemicals, determination of estimated exposure and risk based limits and maximum acceptable concentrations in different compartments of the environment – ambient air, waters, soil and food products. However, this is soon to change as the ability to collect, analyze and interpret the required information is becoming increasingly more efficient and cost effective. Full implementation of the new processes have to involve education on both part of the experimentalists who are generating the data and the models, and the risk assessors who will use them to better protect human health and the environment.

The diffusive gradients in thin-films (DGT) technique is a means of measuring the concentration and speciation of metals in natural waters. Edited by one of the pioneers of the technique, this unique volume provides a complete and authoritative guide to the theory and applications of DGT. The book includes explanations of the fundamental principles of DGT, accessible to readers with a modest background in chemistry, as well as more advanced chapters that provide a thorough treatment of the physical and chemical dynamics of this technique and evaluate how well it mimics the biological uptake process. Chapters on natural waters, soils and sediments illustrate the applications of DGT, and detailed instructions are included on how to use DGT in practice. Combining the fundamentals of DGT with more advanced principles, this is an indispensable text for students, researchers and professional scientists interested in the chemistry of natural waters, soils and sediments.

This authoritative volume reviews the environmental chemistry and toxicological effects of a marine pollutant of exceptional potency, tributyltin (TBT), and outlines the international response to control TBT. TBT compounds have been widely utilised in marine anti-fouling paint formulations to obtain increased fuel efficiencies and long lifetimes for maritime vessels and structures. However, its extreme toxicity has resulted in numerous adverse biological effects, and its persistence ensures that such problems are likely to continue. A wide variety of disciplines are brought together to illustrate the general principles, pathways and problems involved in identifying and quantifying an environmental toxin, elucidating deleterious biological consequences, and the legal framework that can invoke mitigation via regulation. This text not only has wide appeal for undergraduate courses in environmental science, chemistry, and marine ecology, but also forms a valuable sourcebook for environmental planners and serves as a 'successful' case study for undergraduate courses in environmental law, planning and science.

La pollution atmosphérique est une des premières préoccupations sociétales en matière d'environnement. Les métaux émis dans l'air s'accumulant dans la biosphère et n'étant pas bio-dégradables, ces derniers peuvent se retrouver transférés le long de la chaîne alimentaire et provoquer d'éventuels effets sur la santé humaine et les écosystèmes. Les données exposées dans cet ouvrage ont été obtenues par l'exploitation de la deuxième campagne française de biosurveillance des retombées atmosphériques de métaux en pollution de fond, que soutient l'Agence de l'Environnement et de la Maîtrise de l'Énergie, et qui est mis en œuvre par le Muséum National d'Histoire Naturelle. Ce réseau de surveillance utilise sur plus de 500 sites des organismes bioaccumulateurs (des mousses) dans lesquels une vingtaine de métaux et d'éléments traces surveillés sont dosés (notamment, arsenic, cadmium, chrome, cuivre, fer, mercure, nickel, plomb, vanadium et zinc). Cette campagne s'est déroulée en 2000. La distribution spatiale de 10 métaux en France est ici représentée par des cartes qui permettent de situer ces résultats dans un contexte européen, et d'évaluer pour la première fois au niveau national quelles sont les tendances d'évolution, sur cinq ans environ, des niveaux de dépôts en France métropolitaine.

A systematic survey of the dibenzanthracenes and of their chemical, physiochemical, and biological properties, this book treats the nomenclature, the chemical and physical properties, and the synthesis and preparation of the five principal isomers of the dibenzanthracene series: dibenz (a,h), dibenz (a,c), dibenz (a,j), anthracene, benzo(a)naphthacene, and pentacene. Other chapters are devoted to their occurrence and analysis in the environment, in industrial processes and effluents, and in foodstuffs. The second part addresses their biological activity and reviews the metabolism, cellular interactions, toxicology, mutagenicity, and carcinogenicity of the dibenzanthracenes. The final chapter is devoted to structure-activity relationships in this class of the aromatic compounds.

Der stumme Frühling erschien erstmals 1962. Der Titel bezieht sich auf das eingangs erzählte Märchen von der blühenden Stadt, in der sich eine seltsame, schleichende Seuche ausbreitet … Das spannend geschriebene Sachbuch wirkte bei seinem Erscheinen wie ein Alarmsignal und avancierte rasch zur Bibel der damals entstehendenÖkologie-Bewegung. ZumerstenMal wurde hier in eindringlichem Appell die Fragwürdigkeit des chemischen Pflanzenschutzes dargelegt. An einer Fülle von Tatsachen machte Rachel Carson seine schädlichen Auswirkungen auf die Natur und die Menschen deutlich. Ihre Warnungen haben seither nichts von ihrer Aktualität verloren.

»Ich bin einer von ungezählten Millionen, die durch Nelson Mandelas Leben inspiriert wurden.« Barack Obama Eine fast drei Jahrzehnte währende Gefängnishaft ließ Nelson Mandela zum Mythos der schwarzen Befreiungsbewegung werden. Kaum ein anderer Politiker unserer Zeit symbolisiert heute in solchem Maße die Friedenshoffnungen der Menschheit und den Gedanken der Aussöhnung aller Rassen wie der ehemalige südafrikanische Präsident und Friedensnobelpreisträger. Auch nach seinem Tod finden seine ungebrochene Charakterstärke und Menschenfreundlichkeit die Bewunderung aller friedenswilligen Menschen auf der Welt. Mandelas Lebensgeschichte ist über die politische Bedeutung hinaus ein spannend zu lesendes, kenntnis- und faktenreiches Dokument menschlicher Entwicklung unter Bedingungen und Fährnissen, vor denen die meisten Menschen innerlich wie äußerlich kapituliert haben dürften.

Ziel dieser Darstellung ist es, eine Übersicht über die wichtigsten Reaktionen von Schadstoffen in der Umwelt und deren Bedeutung für Atmosphäre, Wasser und Boden sowie für Lebewesen zu geben. Hierzu werden die wichtigsten Abbau- und Entgiftungsreaktionen einiger Schadstoffe kurz skizziert und neben natürlichen Abbaureaktionen auch technische Reinigungsverfahren angesprochen. Die vorgestellten Schadstoffe und deren Reaktionen werden wiederholt in Beziehung zu toxikologischen und ökologischen Aspekten gesetzt, um den interdisziplinären Charakter des Wissensgebietes "Umweltbelastung" zu verdeutlichen.
