Book Synopsis Microbial Degradation of Xenobiotics by : Shree Nath Singh
Download or read book Microbial Degradation of Xenobiotics written by Shree Nath Singh and published by Springer Science & Business Media. This book was released on 2011-10-07 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our interest in the microbial biodegradation of xenobiotics has increased many folds in recent years to find out sustainable ways for environmental cleanup. Bioremediation and biotransformation processes harness the naturally occurring ability of microbes to degrade, transform or accumulate a wide range of organic pollutants. Major methodological breakthroughs in recent years through detailed genomic, metagenomic, proteomic, bioinformatic and other high-throughput analyses of environmentally relevant microorganisms have provided us unprecedented insights into key biodegradative pathways and the ability of organisms to adapt to changing environmental conditions. The degradation of a wide spectrum of organic pollutants and wastes discharged into the environment by anthropogenic activities is an emerging need today to promote sustainable development of our society with low environmental impact. Microbial processes play a major role in the removal of recalcitrant compounds taking advantage of the astonishing catabolic versatility of microorganisms to degrade or transform such compounds. New breakthroughs in sequencing, genomics, proteomics, bioinformatics and imaging are generating vital information which opens a new era providing new insights of metabolic and regulatory networks, as well as clues to the evolution of degradation pathways and to the molecular adaptation strategies to changing environmental conditions. Functional genomic and metagenomic approaches are increasing our understanding of the relative importance of different pathways and regulatory networks to carbon flux in particular environments and for particular compounds. New approaches will certainly accelerate the development of bioremediation technologies and biotransformation processes in coming years for natural attenuation of contaminated environments

Book Synopsis Toxicology of Organophosphate and Carbamate Compounds by : Ramesh C Gupta
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 781 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

Book Synopsis Some Organophosphate Insecticides and Herbicides by : IARC Working Group on the Evaluation of Carcinogenic Risks to Humans
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.
Book Synopsis The Non-halogenated Flame Retardant Handbook by : Alexander B. Morgan
Download or read book The Non-halogenated Flame Retardant Handbook written by Alexander B. Morgan and published by John Wiley & Sons. This book was released on 2014-04-07 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-stop, practical handbook containing all of the current commercial non-halogenated flame retardant technologies as well as experimental systems near commercialization In response to the emphasis on replacing halogenated flame retardants with alternate technologies, this handbook focuses on existing non-halogenated flame retardants and the experimental close-to-production systems that are available today. The Non-Halogenated Flame Retardant Handbook starts with an overview of the regulations and customer perceptions driving non-halogenated flame retardant selections over older halogenated technologies. It then moves on to cover the known major classes of non-halogenated flame retardants, before concluding with the current niche-performing technologies and untried commercial contenders of the future. The Non-Halogenated Flame Retardant Handbook: Takes a practical approach to addressing the narrow subject of non-halogenated flame retardancy—placing more emphasis on flame retardant selection for specific plastics, practical considerations in flame retardant material design, and the various technologies’ strengths and limits Focuses on the proper use of non-halogenated flame retardants, rather than the mechanics of how they work Discusses important future trends in flame retardancy Features sections written by industrial and chemical experts who know how to apply the technology to polymers for fire safety needs
Book Synopsis Cholinesterases and Anticholinesterase Agents by : George B. Koelle
Download or read book Cholinesterases and Anticholinesterase Agents written by George B. Koelle and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1228 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
