Download or read book International Code of Conduct on Pesticide Management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-09-03 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.
Download or read book Environmental Impact of Polynuclear Aromatic Hydrocarbons 2007 written by Chimezie Anyakora and published by . This book was released on 2007-01-01 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contamination of the environment by polynuclear aromatic hydrocarbons (PAHs) is becoming a rising environmental concern. Since the implication of these compounds as cancer causing agents several years ago, there has been a renewed interest in them. Many regulatory bodies have continually pushed for tighter legislature on PAHs. Hundreds of research papers have focused on this subject. In these papers the angle of focus varies. Some focused on the impact on the environment in general, some focused on carcinogenesis, carcinogenicity and toxicity of these compounds. Others focused on the analytical methodologies. All these papers have contributed a lot to deeper understanding of the nature and importance of PAHs. This book is an attempt to assemble several experts in the field to bring out some up to date experiences in different aspects of PAHs hence allowing the impact on the environment to be better appreciated. This book is aimed at researchers, scientists and regulators in environmental sciences. It is made up of 14 chapters which focus on different aspect of PAHs. The chapters include: Chemistry of Polynuclear Aromatic Hydrocarbons; Toxicity, gentocity and carcinocity of PAHs; Toxicokinetics of PAHs; Bioremediation of PAHs; Structure activity relationship of PAHs; Biomarkers of PAHs exposure; Impact of PAHs on marine organisms in polluted sites; Embryotoxicity of PAHs; Application of PAHs in Chemical Fingerprinting; Sample Preparation; Analysis of PAHs with HPLC; Analysis of PAHs with GC and Analysis of PAHs with MECC. The first chapter of the book serves as a brief introduction to PAHs. It focuses on the Chemistry of these compounds. It briefly describes classification, nomenclature, properties and reactions of PAHs, laying more emphasis on sixteen US EPA priority PAHs. The next chapter goes straight to the toxicity, genotoxicity and carcinogenicity of PAHs. This chapter reviews widely the important findings on the toxicity, cytotoxicity, ecotoxicity, neurotoxicity of PAHs. Epidemiological studies on PAHs are also reviewed and monitoring methods are well described. Third chapter reviews the vast literature on the toxicokinetics of PAHs. It briefly describes the concept of toxicokinetics in general (absorption, distribution metabolism and excretion) and the reviews important findings on the toxicokinetics of PAHs in the body. This chapter gives more emphasis on sixteen EPA priority PAHs especially benzo(a)pyrene because of the widespread study on them. Chapter four of this book deals with Biomarker of Exposure of PAHs. It reviews a total of 132 studies on biomarkers of PAHs exposure which include studies on children, and workers of various occupations. The review focuses on the use of urinary 1-hydroxypyrene (1-HP) as a biomarker of environmental and occupational exposure to PAHs. Chapter five of this book looks at Fish Embryos and PAH toxicity. Based on years of study, this chapter proposes that embryonic exposure to PAHs causes a wide variety of effects, many of which extend to later life stages including morphological defects, reduced growth, reduced predator avoidance and prey capture, depressed immune function, cancer, genetic changes, and population declines. This chapter is of great interest since most bioassay procedures do not capture the later life impact. The next chapter deals with Structure Activity Relationship. This handles the topic in a unique way by looking at PAH molecules that have been implicated in cancer and correlating their carcinogenic activities with known structural features that promote the ability of the compound to bind to the DNA molecule. Chapter seven looks at the Impact of PAHs on Marine Organisms in Polluted Sites. This chapter shows the levels of PAH contamination in various regions across the world stressing their hazards. It also presents fate, uptake and elimination of PAHs from marine organisms. The next chapter deals with bioremediation of PAHs. This chapter describes various treatment methods for PAH contaminated soils including: incineration, fixation, solvent extraction wet oxidation, landfill and bioremediation, but focuses more on bioremediation method and technology. Chapter nine deals with the Application of PAHs in Chemical Fingerprinting. It reviews various diagnostic ratios that are employed in determining source specific information for contaminated sites. The last five chapters focus on the analysis of PAHs which are very important. Without a proper measurement for the amount of PAHs in the environment we will not be able to assess their impact. Among the chapters that focus on the analysis of PAHs the first two deal with pre analysis which are extraction and sample preparation. The others deal with PAH analytical techniques such as high performance liquid chromatography, gas chromatography and micellar electrokinetic capillary chromatography. Various chapters of this book were written by several scientists who have good experience in the field hence combining existing body of knowledge in the field with practical research findings. For instance, Dr. Mark Carls and Dr. Jeep Rice wrote on embryotoxicity which is mainly a result of their several years of study at NOAA Alaska. Prof. Philip Marrriot and his coauthors in their chapter on GC analysis of PAHs gave a great insight on the result of their research using GCxGC which they have been working on at Australian Centre for Research on Separation Sciences. Dr. Arbabi and his coauthors gave an insight on their research on bioremediation of PAHs in Iran. Dr. Hansen s chapter on Biomakers of PAHs exposure (coauthored by some of her colleagues) is a result of several years of research at the National Research Centre for the Working Environment, Denmark. Toxicity, genotocity and Carcinogenicity of PAHs written by Dr. Delia of National Institute of Occupational Safety and Prevention, Rome had a slant of her research and findings on PAH contamination over several years. The chapter on sample preparation was written by Dr. Marvin of Environment Canada who has been involved in PAH research at the agency for some years. Prof. John Hardley and his coauthors wrote on PAH extraction which is the core of their research. Dr. Said of National Institute of Oceanography and Fisheries, Egypt gave a good insight on the effect of PAH contamination on marine life in the world with more emphasis on the Red Sea. Prof. Gonzalez and his colleagues gave an overview based on extensive experience on HPLC analysis of PAHs, while Prof. Chang of Taiwan National University (and his coauthors) explored all the relevant issues in PAH analysis using MECC. Prof. Coker and I reviewed the extensive literature on Toxicokinetics of PAHs and Structure Activity Relationship of the compounds. This book is certainly not exhaustive but all the chapters were written with sufficient relevant and recent references to help both advanced and intermediate audience get deeper insight on the subject. There are a number of materials on PAHs which have played important role in this book. Polycyclic Aromatic Hydrocarbons by Ronald G. Harvey has been of great importance and provided initial reading for the first chapter of this book. I thank very much Prof. Zhendi Wang, who even though was not able to contribute to this book nominated a number of authors. Over these years of my research on PAHs, a number of people have played outstanding and prominent role, among them are Prof. Herbert Coker of University of Lagos and Prof. Pete Palmer of San Francisco State University. I thank very much Prof. Vincent Anigbogu, formerly at Clarke Atlanta University who was part of the initial plan for this book and who has encouraged and given important inputs throughout this period. Dr. Cornelius Uboh of University of Pennsylvania gave some useful insight for the book. I thank very much my colleagues at the University of Lagos especially Dr. Biodun Ayoola who read through some of the chapters and provided her kind input. I also wish to express my gratitude to some other scientists at the University of Lagos who are also seriously engaged in PAHs research namely Dr. Kehinde Olayinka and Prof. Babajide Alo, and so many colleagues and students with whom I have discussed this project.
Download or read book Ecology of Shallow Lakes written by Marten Scheffer and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Shallow Lakes brings together current understanding of the mechanisms that drive the diametrically opposite states of water clarity, shown by the cover paintings, found in many shallow lakes and ponds. It gives an outline of the knowledge gained from field observations, experimental work, and restoration studies, linked by a solid theoretical framework. The book focuses on shallow lakes, but the lucid treatment of plankton dynamics, resuspension, light climate and the role of vegetation is relevant to a much wider range of aquatic systems. The models that are used remain simple and most analyses are graphical rather than algebraic. The text will therefore appeal to students, scientists and policy makers in the field of ecology, fisheries, pollution studies and water management, and also to theoreticans who will benefit from the many real-world examples of topics such as predation and competition theory, bifurcation analysis and catastrophe theory. Perhaps most importantly, the book is a remarkable example of how large field experiments and simple models can catalyze our insight into complex ecosystems. Marten Scheffer wrote this book while at the Institute of Inland Water Management and Waste Treatment, RIZA, Lelystad, The Netherlands. He is currently at the Department of Water Quality Management and Aquatic Ecology of the Wageningen Agricultural University. Reviews `Much rarer are textbooks that so succinctly sum up the state-of-the-art knowledge about a subject that they become instant `bibles'. This book is one of these. It is probably one of the best biological textbooks I have read. Scheffer masterfully pulls all this information together under one cover and presents a coherent account, which will serve as a benchmark for the subject. The reader will not gain any great insight into the breeding biology of pike from this book, nor learn much about dragonflies or newts. They will, however, come to understand the essential nature of shallow lakes or, as the author puts it, `how shallow lakes work'. Overall, this book will be of great interest to practical and theoretical ecologists, students and managers in all fields of biology. All freshwater ecologists should certainly read it.' Simon Harrison in Journal of Ecology, 86 `The book by Scheffer can be seen as a milestone in the recognition of shallow lakes as a research topic in its own right. Scheffer uses three approaches concurrently to unravel the functioning of shallow lakes: 1) statistical analysis of large datasets from a variety of lakes; 2) simple abstract models made up of a few non-linear ordinary differential equations, which he calls `mini-models'; and 3) logical reasoning based on a mixture of results from fieldwork, experiments and models. What is new is that Scheffer links mathematics very nicely with what one feels is a correct description of the functioning of a shallow lake. Employing logical reasoning, Scheffer combines all these sources of knowledge into a general, coherent picture of the functioning of a shallow lake.' Wolf Mooij in Aquatic Ecology, 32

Download or read book The Protective Arm of the Renin Angiotensin System RAS written by Thomas Unger and published by Academic Press. This book was released on 2015-04-18 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Protective Arm of the Renin Angiotensin System: Functional Aspects and Therapeutic Implications is the first comprehensive publication to signal the protective role of a distinct part of the renin–angiotensin system (RAS), providing readers with early insight into a complex system which will become of major medical importance in the near future. Focusing on recent research, The Protective Arm of the Renin Angiotensin System presents a host of new experimental studies on specific components of the RAS, namely angiotensin AT2 receptors (AT2R), the angiotensin (1–7) peptide with its receptor Mas, and the enzyme ACE 2, which exert significant beneficial, health-promoting actions by counterbalancing the well-known harmful arm of the RAS with its classical angiotensin AT1 receptor. This innovative concept of the protective arm of the RAS, examined in this reference, represents an indispensable background and will be a strong support for biomedical students, researchers, cardiologists, surgeons, nephrologists, diabetologists, and endocrinologists, as well as any other physician or researcher concerned with RAS physiology, pathophysiology and clinical implications. Provides a complete understanding of the protective side of the Renin Angiotensin System (RAS) involving angiotensin AT2 receptor, ACE2, and Ang(1-7)/Mas receptor Combines the knowledge of editors who pioneered research on the protective renin angiotensin system including; Dr. Thomas Unger, one of the founders of AT2 receptor research; Dr. Ulrike M. Steckelings, who contributed significantly to first preclinical studies with a novel specific AT2-agonist, and Dr. Robson Santos who pioneered research on angiotensin-(1-7) and its receptor Mas. Shows that the protective RAS axes are able to ameliorate the course of several cardiovascular, renal, metabolic and neurological diseases Provides the basis for the understanding of a novel therapeutic approach to stimulate components of the protective arm of the RAS.

Download or read book Pyrethroid Insecticides written by Ethel Eljarrat and published by Springer Nature. This book was released on 2020-08-04 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the latest developments concerning the analysis, fate, behaviour and toxicity of pyrethroid insecticides. Over the last few decades, pyrethroid insecticides have increasingly replaced organochlorine pesticides due to their relatively lower mammalian toxicity, selective insecticide activity and lower environmental persistence. They represent 25% of global sales of insecticides, and are considered to be “safe” since they are converted to non-toxic metabolites by oxidative metabolism in fish and by hydrolysis in mammals. However, recent studies have demonstrated their environmental ubiquity, their bioaccumulation and their toxicity in various aquatic and terrestrial organisms, and even in humans. Featuring contributions by leading experts, the book discusses the physico-chemical properties and uses of pyrethroid insecticides; the latest chemical analytical methods; their occurrence in the environment, biota and food; and their isomeric and enantiomeric behaviour. It particularly highlights the toxicological effects and human exposure to pyrethroid insecticides, and also offers insights into the effects of the salmon industry on the marine environment with a case study of sea lice treatment using pyrethroids. This comprehensive book is a valuable source of information for environmental scientists, policymakers and producers interested in issues related to pyrethroid insecticides.

Download or read book Indigenous Mexican Migrants in the United States written by Jonathan Fox and published by Center for U.S.-Mexican Studies University of Cali. This book was released on 2004 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The multiple pasts and futures of the Mexican nation can be seen in the faces of the tens of thousands of indigenous people who each year set out on their voyages to the north, as well as the many others who decide to settle in countless communities within the United States. To study indigenous Mexican migrants in the United States today requires a binational lens, taking into account basic changes in the way Mexican society is understood as the twenty-first century begins. This collection explores these migration processes and their social, cultural, and civic impacts in the United States and in Mexico. The studies come from diverse perspectives, but they share a concern with how sustained migration and the emergence of organizations of indigenous migrants influence social and community identity, both in the United States and in Mexico. These studies also focus on how the creation and re-creation of collective ethnic identities among indigenous migrants influences their economic, social, and political relationships in the United States. of California, Santa Cruz
Download or read book Tropical Forests and the Human Spirit written by Roger D. Stone and published by Univ of California Press. This book was released on 2001 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book is a remarkably personal report of the authors’ trans-tropical experiences with forest dwellers. The experience was extensive, sometimes spanning years, and the report is the work of professional reporters, experienced at reaching to the core of critical issues of life and survival. The story is not a pretty one, and the prognosis is not good. But in their eyes the key lies in restoring and defending the rights of forest dwellers and encouraging in every way their age-old interest in preserving the integrity of forest lands. The authors are familiar with the international agencies and their programs, their successes and failures. Roger Stone was intimately involved in the World Commission on Forests and Sustainable Development and draws heavily on that experience. The book will strengthen the conclusions of that Commission to the effect that the world’s future lies heavily entangled with the continuity of forests globally, and that continuity hinges on respect for local interests."—George M. Woodwell, Director, Woods Hole Research Center "For twenty years, we have watched TV specials on the destruction of tropical forests -- an acre a second lost, every second for twenty years. This beautifully written book takes you right to the middle of the current international debate about what to do about it. It pulls no punches and proposes its own provocative solution. It offers a perspective that cannot be ignored and an answer that needs to be tried."—James Gustave Speth, Yale School of Forestry and Environmental Science "For more than a century, the conservation movement has dedicated its energy to protecting the Earth’s biodiversity. WWF has built its conservation philosophy and foundation for over forty years on principles of sound science, effective public policy, and recognition of the fundamental role local people bring to achieving tangible conservation results on the ground. Roger Stone and Claudia D’Andrea take us on a tour of the tropical forested regions of the world and capture important lessons about the merits of local control over forest resources. Their wide-ranging portrayal of community-based forest management arrangements, set within the global context of deforestation and loss of biodiversity, provides compelling testimony to the wisdom of empowering local people and nurturing their spirit as effective forest stewards."—Kathryn S. Fuller, President, World Wildlife Fund
