This book was released on 2012-12-06 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid progress in the field of organophosphate compounds has made this new edition necessary. Particular attention has been paid to new developments in biologically active products as this is probably of greatest interest to practical chemists. I have therefore updated the chapter on chemistry and, in connection with this, rewritten the chapter on metabolism. I should especially like to thank Professor Dr. HELLMUT HOFFMANN for his constant encouragement and interest in my work and for many fruitful discus sions. The co-author to the 1st edition, Dr. KARL-JULIUS SCHMIDT, died suddenly on November 21, 1980. I treasure the memory of a valued colleague of many years standing. Elberfeld, January 1982 CHRISTA FEST VII Preface to the First Edition Our intention has been to provide a short introduction to the chemistry and mode of action of insecticidal phosphoric acid compounds, with particular ref erence to the relationship between structure and activity. The yearly produc tion of these pesticides is now approaching 100,000 tons and thus offers an im portant example of applied research. If, however, one examines the historical development of these compounds, it is apparent that this was preceded by a hundred years of pure chemistry of phosphorus.

Book excerpt: Our intention has been to provide a short introduction to the chemistry and mode of action of insecticidal phosphoric acid compounds, with particular reference to the relationship between structure and activity. The yearly production of these pesticides is now approaching 100,000 tons and thus offers an important example of applied research. If, however, one examines the historical develop ment of these compounds, it is apparent that this was preceded by a hundred years of pure chemistry of phosphorus. The utility of the phosphoric acid pesticides is undisputed today - and furthermore it can be expected that they will solve many of the world's nutritional problems" yet from this field of applied research many paths are now leading back into basic research in chemistry, biochemistry, biology and toxicology etc. This clearly illustrates the problem of attempting to define pure and applied research. Originally, this book was conceived for students of chemistry who, on completion of their study, were uncertain about the place of applied research in industry but it was soon clear that such material, when supplemented with further data, would serve as an introduction to the field of pesticidal phosphoric acid compounds for many technicians, officials and scientists who, in various authorities in agriculture, in chemical and biological research, are concerned with the problems of crop protection and more recently with questions of pollution of the environ ment.

Download or read book The Chemistry of Organophosphorus Compounds written by Deacon Palmer and published by States Academic Press. This book was released on 2023-09-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organophosphorus compounds are derivatives of phosphoric, phosphinic or phosphonic acid in which the oxygen atoms directly bind with the phosphorus atom and can be replaced by the atoms of nitrogen or sulfur. They are primarily used as pesticides and insecticides, and serve as a substitute to chlorinated hydrocarbons persisting in the environment. Despite their extensive uses, certain organophosphorus compounds are toxic for human beings. These compounds are abundant in nature and due to their inherent chemical properties, play a vital role in various sectors. Asymmetry, multivalency, variable oxidation states and metal-binding properties are a few of the notable characteristics that enhance their identification as a distinct and adaptable family of chemicals. There has been rapid progress in organophosphorus chemistry and its applications are finding their way across multiple industries. This book aims to shed light on some of the unexplored aspects of organophosphorus chemistry and the recent researches in this field. It also aims to equip students and experts with the advanced topics and upcoming concepts in this area of chemistry.
Download or read book Toxicology of Organophosphate and Carbamate Compounds written by Ramesh C. Gupta and published by Academic Press. This book was released on 2011-04-28 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Pesticides in the Diets of Infants and Children written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.
Download or read book Some Organophosphate Insecticides and Herbicides written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of some organophosphate insecticides and herbicides, including diazinon, glyphosate, malathion, parathion, and tetrachlorvinphos. Diazinon acts on a wide range of insects on crops, gardens, livestock, and pets, but most uses have been restricted in the USA, Canada, and the European Union since the 1980s. Glyphosate is the most heavily used agricultural and residential herbicide in the world, and has been detected in soil, air, surface water, and groundwater, as well as in food. Malathion is one of the oldest and most widely used organophosphate insecticides, and has a broad spectrum of applications in agriculture and public health, notably mosquito control. The insecticide parathion has been largely banned or restricted throughout the world due to toxicity to wildlife and humans. Tetrachlorvinphos is banned in the European Union, but continues to be used in the USA and elsewhere as an insecticide on animals, including in pet flea collars. The IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of these agents.

Download or read book Organophosphorus Pesticides written by Neil Wilkinson and published by Nova Science Publishers. This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, organophosphorus compounds (OP) are considered some of the most toxic substances synthesised by man. These compounds are widely used in agriculture, residential gardening and in pest control programs, as well as in veterinary practices of the modern world. The primary toxicity of organophosphates is associated with the inhibition of acetylcholinesterase in the central and peripheral nervous system, resulting in acetylcholine accumulation and consequently disrupted neurotransmission. In this book, Chapter One provides an overview of recent studies regarding toxic effects of organophosphates, the methods of their removal, and detoxification in live organisms. Chapter Two summarizes the results of monitoring agricultural products for the presence of organophosphorus pesticides, putting a special emphasis on potential ways for reduction of their levels. The final chapter focuses specifically on the structural features, applications, toxicity mechanisms and effects of exposure on human health of fenitrothion, a non-systemic organophosphorous insecticide.
Download or read book Pesticide Chemistry and Toxicology written by Dileep K. Singh and published by Bentham Science Publishers. This book was released on 2012-01-30 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticide control involves killing pest organisms or otherwise preventing them from destructive behavior. Pesticides are either natural or synthetic and are applied to target pests in a myriad of formulations (EC,WP, SP, FP, G etc.) and application technology systems (sprays, baits, slow-release diffusion, dust, etc.). In recent years, the bacterial genes coding for insecticidal proteins have been incorporated into various crops that dealt with the mortality of the pests feeding on them. Many other eco-friendly methods for insect pest control such as Integrated Pest Management (IPM), use of bio-pesticides etc., are becoming popular. Bio-pesticides and IPM should show good growth in the future, as there is growing concern for the eco-friendly organic agriculture and could be achieved through Good Agriculture Practices (GAP). Use of pesticides requires a proper understanding of the chemistry, their handling and their use in crop protection or hygiene. These are toxic chemicals and require a good understanding of therapy and antidotes at the time of poisoning. This e-book covers pesticide chemistry, metabolic/degradation pathways, biochemical toxicology, therapy and antidotes, nano-pesticides and terminologies associated with pesticide toxicology. the book should serve as a text book for academia, or as a reference work for agriculturists, environmentalists and industry professionals.
