Download or read book Copper in Animal Wastes and Sewage Sludge written by P. L'Hermite and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication constitutes the Proceedings of a Workshop held in Bordeaux (France) on 8th - 10th October, 1980, under the auspices of the Commissior: of the European Communities, as part of the CEC research programme on 'Effluents from Livestock' and the Concerted Action COST 68 bis 'Treatment and Use of Sewage Sludge'. Major changes have taken place in livestock production techniques in recent years. One of the most important developments has been in the field of animal nutrition. Animals are fed to gain maximum liveweight in close relationship with market requirements for carcass and meat quality. With regard to pig production, dietary formulation is based on scientific principles and feed includes a large variety of ingredients to supply optimum feed rations for 'standardised' animals. In order to increase growth rate and to improve feed conversion, copper is added to the ratio~s of fattening pigs in a number of countries, in accordance with the provisions of Council Directives concerning additives in feedingstuffs, as last amended by the 23rd Commission Directive of 4th July 1980.
Download or read book Trace Element Contamination of the Environment written by D. Purves and published by Elsevier. This book was released on 2012-12-02 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is hard to imagine a more concise summary of the prodigious work and voluminous publications in this field... This volume should be available to students at the undergraduate level, to those in law school, and to all seriously concerned about an extremely important problem. This review in Choice was just one of the many favourable comments that greeted the appearance of the first edition of this book when it appeared in 1977. Since then, there has been an explosion of interest in almost every aspect of research in environmental pollution. The aim of this new edition, however, remains the same i.e. to evaluate the global biological consequences of dispersal of trace elements, originally mined from localized limited deposits, in the environment. In treating the problems of metal contamination of the environment, the author considers the problems of environmental pollution involving metals and the problem of exhaustion of finite reserves of ores of metals, such as cadmium, copper, lead, mercury, nickel and zinc, as aspects of a single global problem. A broad picture is presented of the overall process of dispersal of trace elements in the environment and the biological consequences of this process are documented with the aid of an intensive list of references. The book will be invaluable as a definitive reference source covering this field of interest for a wide range of people (environmentalists and conservationists, those concerned with management of resources and waste disposal, and agricultural chemists and soil scientists.)

Available in PDF, EPUB and Kindle. Book excerpt: Recent Advances in Animal Nutrition — 1982 focuses on the compositions of animal feeds. The book first discusses the presence of molds and mycotoxins in animal feeds. Controlling mycotoxin exposure, formation and effects of mycotoxins, and microbiology of feeds are described. The text surveys the anti-nutritive factors in animal feeds. Substances depressing digestion or metabolic utilization of proteins; substances reducing the solubility or interfering with the utilization of mineral elements; and substances inactivating or increasing the requirements of vitamins are discussed. The book also highlights oilseed meals for livestock feeding; the use of databases for the composition and nutritive value of animal feeds; and energy evaluation of poultry rations. The text underscores the influence of nutrition on hatchability, including the composition and size of hatching eggs; the right amounts of proteins, lipids, vitamins, and minerals; feed ingredients; and feeding practices. The book also discusses the energy and protein requirements of pigs and methods used in the analysis of the energy content of ruminant feeds. The selection is a good source of data for readers interested in studying the compositions of animal feeds.

Download or read book Trace Element Contamination of the Environment written by David Purves and published by Elsevier. This book was released on 2012-12-02 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental Aspects of Pollution Control and Environmental Science 1: Trace-Element Contamination of the Environment investigates the global biological consequences of dispersal of trace elements that are mined from localized limited deposits in the environment. It considers the problem of trace-element contamination of the biosphere as an environmental pollution and as part of the ecological crisis as a whole. Comprised of eight chapters, this volume begins with an overview of trace-element contaminants, such as lead, cadmium, and mercury. It then discusses factors affecting the trace-element composition of soils, including sulfur, lime, and fertilizers. It explains as well the trace-element contamination of the atmosphere and hydrosphere, the sources of trace-element contamination of soils, and the availability of trace elements in the soil. The consequences of trace-element contamination of the soil, including its effects on crops and animals, are also discussed. The book also provides ways to prevent dispersal of metals in the environment. This book will be an essential reading for undergraduates, law students, and those who are interested about environmental pollution caused by trace elements.

Download or read book Environmental Geochemistry and Health written by S.H. Bowie and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main outcomes of the eleven meetings of the Working Party was the recognition of the importance of interdisciplinary studies linking regional geochemistry with plant, animal and human health. The effects of major element deficiencies or excesses on plant health are well known; this is not the case for trace elements. In fact, rapid and reliable analytical methods for determining trace element abundances have only recently become available, and it is to be expected that important new information on trace element levels will be forthcoming. This, however, is only part of the problem because other factors such as element speciation, uptake and transmission may be more significant than total concentration. The pathways of elements from crops to animals are relatively well defined, but the aetiology of diseases attributable to elemental inadequacies or excesses is generally quite complex. Nevertheless, there is good evidence for diseases in livestock in the British Isles induced by deficiencies of Cu, Se and Co and Mo excess. On a world scale there is also convincing data on the effect of Na, P and I deficiencies and F excess on animal health. What is generally lacking, however, is adequate interaction between geochemists and biochemists, veterinary scientists and other concerned with animal health. Interpretation of geochemical data is complex as are connections between elemental abundances and the health of animals.

Available in PDF, EPUB and Kindle. Book excerpt: Trace Elements in Health: A Review of Current Issues presents how some metals affect health, growth, and well-being of man and animals in a variety of ways, when the amounts involved are excessive or deficient. This book discusses the various aspects of trace elements in three points of view. First, the toxicological and beneficial properties are described in eleven chapters. Chapter 1 deals with general toxicological properties, while Chapters 2 to 11 reviews advances in the field of elements that include cadmium, copper, indium, thallium, lead, mercury, molybdenum, selenium, zinc, and transuranic series. The next chapters focus on the genetic effects, health of children, and birth rate problems related to trace elements. Finally, this text concludes with a discussion on the role of trace elements in agriculture, focusing on requirements of plants and animals, consequences of excesses and imbalances of trace elements in soils, and animal diets. This publication is valuable to veterinarians and practitioners of disciplines such as physiology, dietetics, and medicine.
Download or read book Animal Manure on Grassland and Fodder Crops Fertilizer or Waste written by H.G. van der Meer and published by Springer Science & Business Media. This book was released on 1987-08-31 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the occasion of its twenty-fifth anniversary, in 1985, the Netherlands Society for Grassland and Fodder Crops (NVWV) agreed to organize an International Symposium on a topic related to intensive grass and fodder production systems. The theme selected was "Animal manure on grassland and fodder crops: Fertilizer or waste?" This Symposium was organized under the auspices of the European Grassland Federation and held at the International Agricultural Centre in Wageningen from 31 August to 3 September 1987. The problems connected with the disposal of animal waste have received much attention in recent years, especially in regions with intensive animal of animal manure per hectare agricul husbandry. Whereas the production tural land increased strongly, the need for it decreased because of the introduction of cheap inorganic fertilizers which are easier to handle and have a more reliable effect on crop growth. As a consequence, many farmers dispose of animal manure as cheaply as possible, whilst avoiding damage to grassland and crops and paying little attention to effective use of the plants nutrients contained in the manure. Present practices of manure handling and application often lead to environmental problems. The rise in awareness of these problems renewed interest in possibilities to improve the utilization of nutrients from animal manure in crop production. Research on this topic has been stimulated in many countries during the last decade and the aim of this Symposium was to review and assess present-day knowledge.
Download or read book Soils in the Urban Environment written by Peter Bullock and published by John Wiley & Sons. This book was released on 2009-05-13 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban areas contain a wide variety of open spaces, yet much of this has evolved under the pressures of human population with minimal management. The last 40 years have seen problems of varying severity begin to appear, including contamination, erosion, acidification and compaction. These problems have brought attention to the importance of the soil cover, the need for better understanding it, and the need for its protection. This book is a review of state-of-the-art science for soil in urban areas. Based on a meeting organized by the Nature Conservancy Council and the British Society of Soil Science, the nine chapters cover soil classification, contamination by waste and metals, physical and biological properties, nutrient provision and cycling, vegetation, and soil storage. The book provides a basis from which to plan future research and development programs.
Download or read book Biological Monitoring of Heavy Metal Pollution written by M. H. Martin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two decades there has been an increasing public awareness of the hazards that exist from the contamination of the environment by toxic substances. 'Heavy metals' and the terrestrial environment are but one facet of the impact of toxic substances on the natural environment, and the use of biological materials for indicating the occurrence of, and continually monitoring the presence of, these materials is a specific topic which is of considerable interest to a diverse range of individuals, organisations and disciplines. It was our intention when we first en visaged this book that it should contain a description of a range of circumstances in which biological monitoring techniques have been employed in the terrestrial environment and that it should be seen as a practical text which dealt with the merits, shortcomings and suitability of biological monitoring materials. Monitoring is, however, a manifold process. It serves not only to provide information on past and present concentrations of toxic materials in various components of the environ ment, but also to provide information on the processes of environmental release, transport, accumulation and toxicity. Indeed, this may be one of the greatest virtues of biological monitoring over other forms of monitor ing. According to the skill of the staff employed in the monitoring procedure, the information that is accrued can have a vastly different value.
