Toxicology of Organophosphate and Carbamate Compounds


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




Clinical and Experimental Toxicology of Organophosphates and Carbamates


Book Description

Clinical & Experimental Toxicology of Organophosphates and Carbamates considers the histochemical localization of cholinesterase in anticholinesterase poisoning. This book is organized into eight parts encompassing 59 chapters that discuss the pharmacology and toxicology of carbamates, as well as the neurobehavioral toxicology of anticholinesterases. Some of the topics covered in the book are the overview of biological and clinical aspects of organophosphates and carbamates; biochemical determination of cholinesterase activity in fluids and tissues; intermediate syndrome in anticholinesterase neurotoxicity; structure-activity relationships and anticholinesterase activity; and the molecular events in delayed neuropathy. Other parts deal with the cardiac effects of anticholinesterase agents and the ecotoxicological consequences of interactions between avian esterases and organophosphorus compounds. These topics are followed by discussions on the analysis of the cutaneous and respiratory tract absorption of anticholinesterases and the use of organophosphorus compounds as chemical warfare agents. The final parts are devoted to the toxicity of anticholinesterases to aquatic organisms. The book can provide useful information to toxicologists, doctors, students, and researchers.




Toxicology and Pesticide Use in Relation to Wildlife, Organophosphorus, and Carbamate Compounds


Book Description

Organophosphorus and carbonate pesticides are used as insecticides, herbicides, nematicides, acaricides, fungicides, rodenticides, and bird repellents throughout the world. Today, organophosphorus and carbamate pesticides use is widespread on agricultural crops, rangelands, forests, and wetlands. Toxicology and Pesticide Use: Organophosphorus and Carbamate Compounds summarizes what is known about these pesticides from wildlife toxicology literature and discusses the potential hazards to wildlife by examining toxicity, environmental persistence, and use patterns of the pesticides. This information is critical to anyone involved in agriculture or agribusiness because of the impact of recent EPA rulings regarding the administration of these chemicals to crops. The book will interest toxicologists, environmental toxicologists, agrichemists, and all researchers involved in the study of the impact of these chemicals on the environment.




Basic and Clinical Toxicology of Organophosphorus Compounds


Book Description

This book explains the chemistry of Organophosphorus compounds (OPs), their mechanism of toxicity and the history of OPs from their initial discovery to the development of new compounds such as Novichoks. It details the harmful effects to human health both as a result of acute and chronic OP exposure and the necessary clinical management of affected patients to reduce their toxic side effects. The book also explains the detrimental effect that OPs have had on the environment and the efforts being made to prevent this in the future. Finally, the book looks at the incidents where OPs have been used as chemical warfare agents. Basic and Clinical Toxicology of Organophosphorus Compounds aims to act as a comprehensive guide to all aspects of OPs and is a key resource for clinical toxicologists and related health professionals involved in the prevention, diagnosis and clinical management of OP patients, toxicologists and other scientists involved in research on OPs including regulatory issues and postgraduate students in Toxicology and related fields.




Toxicology of Organophosphate Poisoning
