Current Toxicology - Böcker

This book brings together key features of the toxicology and occupational hazards of pesticides and the way their use is regulated in the main trading regions of the world. There are chapters on each of the main groups of insecticides, namely organochlorines, anticholinesterases and pyrethrins and pyrethroids. The book also covers fungicides and herbicides, as well as more specialised agents such as microbial pesticides. The risks and hazards to humans are considered, both occupational and through the consumption of contaminated foodstuffs. Additionally, clinical aspects of pesticide poisoning are discussed. The possibility of harm from pesticide exposure has led to the development of national and international regulations governing the application of pesticides. The book describes the regulatory systems in three major economic areas: the North American Free Trade Area (USA, Canada and Mexico), the European Union and Japan. This book should be of interest to all individuals working on the development and application of pesticides anywhere in the world. All those involved in the manufacture, regulation and toxicology of pesticides should also benefit from reading this book.

This definitive reference work describes in detail the enzyme systems that participate in the metabolism of xenobiotics, particularly medicinal drugs. Each chapter focuses on a specific enzyme system, emphasising its role in the activation and detoxication of chemicals. Aspects discussed critically include:* enzyme function in the metabolism and bioactivation of xenobiotics* substrate specificity* tissue distribution* species distribution (to include laboratory animals and humans)* hormonal regulation* sex differences* modulation by prior exposure to other chemicals* age-dependent expression* pharmacogenetics and modulation by disease.Enzyme Systems that Metabolise Drugs and Other Xenobiotics will be essential reading for industrial research scientists working in the fine chemicals and pharmaceutical industries, especially those concerned with the safety evaluation of chemicals, and investigating their metabolism, pharmacokinetic characteristics and toxicological properties. The nature and scope of the book will also make it attractive to the research toxicologist and to postgraduate students studying toxicology, as well as to clinicians and pharmacists.

Current Toxicology Series Series Editors Diana Anderson BIBRA Toxicology International, Surrey, UK Michael D Waters Consultant, Chapel Hill, NC, USA Timothy C Marrs Department of Health, London, UK Nutrition and Chemical Toxicity Edited by Costas Ioannides, University of Surrey, Guildford, UK An enormous amount of research is currently devoted to evaluating the role of nutrition in the aetiology of major human diseases and to clarifying the underlying mechanisms. This resurgent interest reflects the realisation that carcinogens may be generated during the normal cooking of food and that they may play a role in human carcinogenesis. Moreover, during the last decade it has become apparent that naturally occurring chemicals in food, primarily of plant origin, can afford effective protection against human cancer and heart disease. As a result, the need for up-to-date information in this subject area has never been greater. Nutrition and Chemical Toxicity deals in depth with the various toxicants found in food including naturally occurring chemicals, fungal contaminants, products of the cooking process and allergens. Other chapters focus on nutritional modulation of cytochromes P450; interactions between drugs and diet; glutathione, sulphur aminoacids and chemical detoxication; modulation of the carcinogenic response by caloric restriction; and lipotropes and chemical carcinogenesis. Further contributions discuss the expression of chemical toxicity in vitamin deficiency and supplementation; safety evaluation of vitamins and minerals; naturally occurring organosulphur compounds as potential anticarcinogens; cancer chemoprevention by tea polyphenols; and animal diets in safety evaluation studies. This timely book is essential reading for professionals involved in cancer research and the safety evaluation of chemicals, food scientists and toxicologists, nutritionists and those involved with food regulation.
