Fate of Pesticides in Large Animals covers the proceedings of the 1976 Fate of Pesticides in Large Animals symposium. The symposium is held at the Centennial Meeting of American Chemical Society and sponsored by the Pesticide Chemistry Division of the ACS. It aims to focus on the fate of pesticides in large animals and to assemble a thesis on the subject covering its theoretical and practical significance. In this book, large animals are particularly considered, because they often metabolize chemicals differently than small laboratory rodents. These differences may prove a basis for the development of concepts pertinent to the phenomenon of selective toxicity. This book is divided into three sections encompassing 14 chapters. The first section delineates the rationale of the symposium and presents topics applicable to all facets of large animal metabolism. The second section focuses on comparative metabolism of selected groups of pesticides, including phenoxy herbicides, insect growth regulators, fungicides, and halogenated hydrocarbons. The third section deals with specific compounds and/or specific large animal species. It includes mirex, chlordane, dieldrin, and polychlorinated biphenyls; p,p'-DDT and p,p'-DDE in pig; phenyl N,N'-dimethylphosphorodiamidate; croneton; and Vacor rodenticide. This book is an invaluable resource for chemists, biochemists, researchers, and toxicologists.

This book discusses studies that have been conducted on various animal species. The book reviews the effects of pesticides through changes in behavior, the nature of morphological and biochemical lesions, as well as the tracking of the metabolic disposition of pesticides in target sites of an organism. In vitro studies provide information regarding cellular responses and biochemical lesions with pesticides. Toxicological profiles of pesticides are cited using different species of animals for in vivo and in vitro studies. This information should help scientists and decision-makers reach conclusions regarding the toxicological effects of pesticides on humans and the environment.

When first developed, chlorinated pesticides such as DDT, dieldrin, and mirex were received with open arms, quickly becoming popular as effective, economic agents against pests. But evidence began to mount that residues of these chemicals remained in the environment, not breaking down, often appearing in plants and animals. By the late seventies many pesticides had achieved a terrible notoriety and were subsequently banned in a number of countries. Of tremendous concern, then, is the persistence of pesticides in the environment. The major thrust of research and development in the area of pesticides has properly been the creation of substances that are both effective and degradable. Yet in order to successfully promote the use of biodegradable pesticides, one must fully understand the mechanism of degradation, and it is to this vital subject that we address ourselves in the present volume. According to the Biodegradation Task Force, Safety of Chemicals Com mittee, Brussels (1978), biodegradation may be defined as the molecular degradation of an organic substance resulting from the complex action of living organisms. A substance is said to be biodegraded to an environmentally acceptable extent when environmentally undesirable properties are lost. Loss of some characteristic function or property of substance by biodegradation may be referred to as biological transformation.

Lebensmittelmonitoring - das von Bund und Ländern durchgeführte Untersuchungsprogramm - ergänzt die amtliche Lebensmittelüberwachung der Bundesländer. Lebensmittelüberwachung kontrolliert die Einhaltung lebensmittelrechtlicher Vorschriften v.a. durch verdachts- und risikoorientierte Untersuchungen. Das Lebensmittelmonitoring hingegen misst und bewertet - wiederholt und repräsentativ - den Gehalt unerwünschter Stoffe (z.B. Pflanzenschutzmittel, Schwermetalle) in und auf Lebensmitteln. Es erkennt Risiken für Verbraucher und stellt sie ab. 2005 wurden 5159 Proben von 50 Lebensmitteln bzw. -gruppen in- und ausländischer Herkunft untersucht.

Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide use--concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agriculture--globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.

This wide-ranging text reviews the wealth of recent research on assessing and managing the risks from pesticide, veterinary and other chemical residues in food. After an introductory chapter on the key issues in food toxicology, Part one covers the assessment and management of risks, with individual chapters on genetic susceptibility to dietary carcinogens, good agricultural practice and HACCP systems, targeted and rapid methods for analysing residues in food and ways of assessing the mutagenicity of chemicals in food. Part two looks at veterinary residues, covering their safety, toxicology and detection. Part three examines pesticides, with chapters on surveillance and detection methods for fungicides and herbicides. In the final part, there are chapters summarising a wide range of other chemical residues in food, from xenostrogens/endocrine disruptors and dietary estrogens to polycyclic aromatic hydrocarbons, dioxins and polychlorinated biphenyls. Pesticide, veterinary and other residues in food is a standard reference for all those concerned with ensuring the safety of food.

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.
