Book Description
This volume pulls together a wealth of up-to-date information on the toxicology of this diverse and ubiquitous class of insecticides. Leading experts review the reactivity of organophosphorus compounds with cholinesterase, as well as their metabolism and biological effects on humans and other nontarget organisms. The book not only covers the anticholinesterase actions of organophosphates, but also other, presumably independent, effects, such as teratogenicity, delayed neuropathy, immunotoxicity, and behavioral toxicity. - Offers crucial overviews of chemical and biochemical reactivity and biological responsiveness of mainly nontarget organisms - Reviews new developments in assessment of metabolism and disposition of organophosphorus compounds - Examines organophosphorus compound-induced toxicity mediated by mechanisms other than inhibition of acetylcholinesterase - Covers new research on differences in toxicity induced by the variety of organophosphorus - Analyzes current controversies on the relevance of certain biochemical parameters in actual organophosphate toxicity in vivo

Book Description
This text/reference book provides the most comprehensive coverage of anticholinesterase compounds (Organophosphates and Carbamates), which constitute the largest number of chemicals that are primarily used as insecticides in agriculture, industry, and around the home/garden. Some OPs (nerve agents) have been used in chemical warfare and terrorist attacks, while some OPs and CMs have been recommended as therapeutic agents in human medicine as well as in veterinary medicine. Many chemicals of both classes are extremely toxic and lack selectivity, thus their inadvertent/accidental use continues to pose a threat to human and animal health, aquatic systems and wildlife. These anticholinesterase agents produce a variety of toxicological effects in target and nontarget organs. In light of this complexicity, this multi-authored book is written by the well known scientists from many countries. The book is organized into nine sections, with a total of 49 chapters, to provide in-depth knowledge on various aspects of OP and CM compounds, including their use, classification, mechanism-based toxicity, and prophylactic and therapeutic measurements. Several chapters are written with special emphasis to cover timely topics, such as chemical warfare agents, physiologically-based pharmacokinetic modeling, structure and function of cholinesterases, paraoxonase, carboxylesterases; developmental neurotoxicity, the intermediate syndrome, oxidative stress, endocrine disruption, and DNA damage/gene expression and carcinogenesis. Section-VI with 5 chapters is specifically devoted to risk assessment, and safety and regulatory guidelines for pesticides. - Describes everything you need to know about Organophosphates and Carbamates - Extensively covers pesticides, nerve agents, therapeutic drugs, and flame retardants - Describes epidemiology of the world's major disasters involving Organophosphates and Carbamates - Covers animal, human, aquatic, and wildlife toxicity of Anticholinesterases - Insights into in-depth cholinergic and noncholinergic mechanisms of toxicity - Describes recent advancements in cholinesterases, paraoxonases, carboxylesterases, oxidative stress, endocrine disruption, cardiac and pulmonary toxicity, and carcinogenesis - Provides in vitro and in vivo models for neurotoxicity testing - Integrates knowledge of studies in lab animals and humans - Offers risk/safety assessment and national/international guidelines for permissible levels of pesticide residues - Describes management of Anticholinesterase poisoning in humans

Book Description
Pesticide Profiles: Toxicity, Environmental Impact, and Fate is like three books in one-it is a profile containing specific information about 137 pesticides, a primer of environmental toxicology, and an extensive trade name index. Profiles of each pesticide contain regulatory information, toxicity assessments, environmental fate data, physical properties, and acceptable exposure limit values. What these values and data mean in terms of human toxicity is clearly interpreted as well. The book also describes the meaning of carcinogenicity and how it is assessed in non-technical terms the non-expert can understand. Readers with a technical background are provided with the data to make their own judgments. In addition to information about specific pesticides, there are sections on general classes of pesticides, such as organophosphates. This information allows readers to make inferences about any pesticide in a class, even if a profile is not provided. Pesticide Profiles: Toxicity, Environmental Impact, and Fate goes beyond the usual listings of toxicity values or environmental half-lives to offer a broad understanding to readers of various backgrounds and interests.

Book Description
The Gulf War in 1990-1991 was considered a brief and successful military operation, with few injuries or deaths of US troops. The war began in August 1990, and the last US ground troops returned home by June 1991. Although most Gulf War veterans resumed their normal activities, many soon began reporting a variety of nonexplained health problems that they attributed to their participation in the Gulf War, including chronic fatigue, muscle and joint pain, loss of concentration, forgetfulness, headache, and rash. Because of concerns about the veterans' health problems, the Department of Veterans Affairs (VA) requested that the Institute of Medicine (IOM) review the scientific and medical literature on the long-term adverse health effects of agents to which the Gulf War veterans may have been exposed. This report is a broad overview of the toxicology of sarin and cyclosarin. It assesses the biologic plausibility with respect to the compounds in question and health effects.

Book Description
This important publication provides a comprehensive summary of data and information on the metabolism and chemical degradation of agrochemicals in soils, plants and animals. Part 1, Herbicides and Plant Growth Regulators, and Part 2, Insecticides and Fungicides, together provide a major bibliography, as each entry is fully referenced. Contents include metabolic products, pathways and mechanisms, together with useful details on physico-chemical properties and mode of action. Both parts are organised by class of chemical for easy reference. There are separate entries for each pesticide, covering most commercially available chemicals in use today. In addition, an overview of the metabolism of each major class provides the reader with an informed summary of key similarities and significant differences between individual chemicals. Information is based primarily on literature from the past 40 years of research, together with some important, previously unpublished work provided by the agrochemical companies. Presented in a systematic, easy-to-read style, with extensive indexing to facilitate the rapid location of required information and the comparison of related compounds, Metabolic Pathways of Agrochemicals is an invaluable reference for chemists, biochemists and biologists working in the discovery, development and registration of agrochemicals, as well as scientists in related areas such as design and mode of action of pharmaceuticals.

Book Description
Few chemical compounds created by man have caused greater controversy than organophosphates. Conceived as insecticides, they have also been developed to become the most feared of chemical weapons. The control of vectors of diseases from which millions die or are disabled is heavily dependent on organophosphates, as are efforts to maintain food production in the face of uncontrolled population growth, diminishing arable land and the possibility of global warming. As the toxicity of organophosphates is non-specific, it has caused ill health and death in man, and has contributed to adverse ecological effects.This book, written by recognised experts, studies and presents information in a manner that basic scientists, medical personnel, environmentalists, agriculturists and those in public health and occupational medicine will find essential when considering the use of organophosphates in their disciplines. The text primarily covers health aspects, with discussions on related social, economic, environmental and agricultural issues that concern all inhabitants of the global village.

Book Description
Although the anticholinesterase (anti-ChE) agents have only limited applica tions in therapy, and from the viewpoint of practical significance they are more appropriately classified as toxic compounds or insecticides than as drugs, in their capacity of pharmacological tools they have few equals. The concept of neuro humoral transmission was originally established largely from experiments in which physostigmine, or eserine, was employed to protect acetylcholine (ACh), the trans mitter of the cholinergic nerves, from rapid hydrolytic destruction by acetyl cholinesterase (AChE) and other cholinesterases (ChE's). Since then, a great num ber of additional reversible and irreversible anti-ChE agents also have been indis pensable in studies of synaptic and neuroeffector transmission, and of other physiological processes. At the same time, there is practically no other class of compounds for which a mechanism of pharmacological action can be described in such concrete biochemical and physiological terms. Consequently, it is not sur prising that a huge literature has developed on these several closely interdependent topics. The assembling anrl proper correlation of this material for the present volume has taken the collaborative efforts of over two dozen . investigators. It iR believed that their contributions to this end will prove invaluable to future in vestigators in providing a ready, inclusive source of established information, in defining areas where further studies are indicated, and in preventing unnecessary duplication of past work. How well these aims have been accomplished will be for time and the reader to judge.
