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 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







Mammalian Toxicology of Insecticides


Book Description

Insects are more similar in structure and physiology to mammals than plants or fungi. Consequently, insecticides are often of greater toxicity to mammals than herbicides. This is particularly the case with neurotoxins. However, some insecticides are targeted at structures or hormonal systems specific to insects (insect growth regulators/chitin synthesis inhibitors) so are less harmful but can still be mildly haematotoxic. There are, therefore, issues specific to insecticides, which do not occur with other pesticides - hence the need for a book specifically on insecticide toxicology in mammals. The book starts with general issues relating to the mammalian toxicity of insecticides, including target/non-target specificity, nomenclature and metabolism of insecticides. It then goes on to discuss specific types of insecticides including: organochlorines; anticholinesterases; pyrethrum and synthetic pyrethroids; nicotine and the neonicotinoids; insect growth regulators/ecdysone agonists/chitin synthesis inhibitors; insecticides of natural origin; biological insecticides; and insecticides used in veterinary medicine.




Organophosphates And Health


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.




Chemical Warfare Agents


Book Description

The first edition of this book, Chemical Warfare Agents: Toxicity at Low Levels, was published just prior to the terrorist attacks of September 11th, 2001. Reflecting a greater sense of urgency within the field of chemical defense since this event, research related to chemical warfare agents (CWAs) continues to expand at a remarkable pace.




Neurotoxicity of Pesticides


Book Description

Neurotoxicity of Pesticides, Volume Four, in this comprehensive serial addresses contemporary advances in neurotoxicology of pesticides by providing authoritative review articles on key issues in the field. Edited by leading subject experts, topics of note in this new release include Organophosphates, OPs, Nerve agents, Pyrethroids, Neonicotinoids and Formamidines, among others.




Toxicological Effects of Veterinary Medicinal Products in Humans


Book Description

Toxicological Effects of Veterinary Medicinal Products in Humans is the first definitive guide to discuss the adverse effects of veterinary medicinal products in humans. The chapters focus on occupational safety and consumer issues and examine the circumstances under which exposure is likely to occur. To be in context, it reviews this against the background of adverse health effects from other sources in the veterinary and farming professions. The book examines adverse drug effects reported to regulatory agencies (mainly the FDAÆs Center for Veterinary Medicine) and then considers a series of individual drugs, including antibiotics, anaesthetics and organophosphorus compounds. The chapters also discuss the fundamental aspects of regulatory issues relating to safety assessment, and examine the manner in which user safety is assessed prior to authorisation/approval and what measures can be taken after authorisation/approval in the light of findings from pharmacovigilance activities. There is growing concern over the issue of antimicrobial resistance and the contribution made by veterinary medicinal products. This too is addressed along with the significance to human health and measures that can be taken to mitigate the effects (if any) of the use of antibiotics in animals e.g. prudent use measures. The book will be an essential resource for medical practitioners in hospitals and general practice, pharmaceutical industry scientists, analysts, regulators and risk managers.

Gulf War and Health


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.
