Hemp fiber is amenable to use in a wide range of products incl. carpeting, home furnishings, construction materials, auto parts, textiles, and paper. Hemp seed, an oilseed, likewise has many uses, incl. industrial oils, cosmetics, pharmaceuticals, and food. In June 2005, legislation that would open the way for commercial cultivation of industrial hemp in the U.S. was introduced at the federal level for the first time. Such a change would mean that state law would determine whether producers could grow and process industrial hemp within state borders, under state regulations. Contents of this report: (1) Intro. and history; (2) Foreign Hemp Production and U.S. Consumption; (3) Review and Analysis of Economic Studies. This is a print on demand pub.

Who put the Hemp in Hempstead? Before the cotton gin, hemp was King. This colorful socio-economic history clears the smoke obscuring hemp's role in battles between Crown and Colony, North & South, the marijuana lobby and their foes.

Lead covers the salient aspects of the chemistry of lead, its environmental impact, and its effects on health.

The technical, economic and social importance of Lead, at the present time, is beyond all doubt. However, over the last few decades little attention has been given to its behaviour (the properties and applications of its compounds, the environmental distribution of these derivatives, and their impacts on living creatures), this book addresses that gap.

It includes coverage of historical aspects, lead mining and production, metal properties, common lead compounds, uses of lead and its derivatives, coordination chemistry, organometallic chemistry, environmental chemistry, toxicity mechanisms, and treatment strategies for lead poisoning. Finally, describing analytical procedures for the determination of lead in chemical, biological and environmental samples.

Written by a team of university teachers and researchers with extensive experience in the fields of the chemistry, analytical determination and environmental and health impact of lead and other heavy metalsFor readers interested in the chemistry and biochemistry of lead and its effects on ecosystemsProvides comprehensive knowledge about lead toxicity and preventive measures against lead poisoning

Advances in Fluorine Science is a new book series presenting critical multidisciplinary overviews on areas in which fluorine and fluoride compounds have a decisive impact. The individual volumes of Advances in Fluorine Science are thematic, addressing comprehensively both the science and applications on topics including the Environment, Green chemistry, Medicine, Health & Life Sciences, New Technologies & Materials Science, Energy and the Earth Sciences. In the present volume, the key-position of fluoro-products in agriculture is reviewed, since a large percentage of agro-chemicals and pesticides contain at least one fluorine atom. However, improvements in the use of fluorine-based products in agrochemicals cannot be developed without taking into consideration a safer environment, on both levels of greener synthesis routes and a reduction of the negative impact on plants and organisms. Within this scope, fluorine has a very peculiar place, since its high reactivity yields several advantages, for instance in by-passing various polluting multi-step reactions.

Fluorine-based materials are reviewed as efficient tools for protecting our cultural heritage. Also using up-to-date techniques such as ion beam analysis, this element can help relative dating applications, ranging from burial durations of archaeological bones and teeth to the determination of exposure ages of meteorites on the Antarctic ice shield.

This book is a must for individuals and companies that have an interest in developing sustainable technology and systems in the complex 'Web of Metals' on a first principles, technological and economic basis, with a focus to the minerals, metals and product manufacturing industries.

In this inter-, intra- and trans-disciplinary book the material/metal cycle will be central, addressing technology as the basis for achieving sustainability within the system of primary mineral and metal producing, and the consumer product material cycles, linked to nature's cycles. The following major topics (not exclusive) are discussed in a detail, which will satisfy company CEO's and students of environment, engineering, economics, and law alike: (i) industrial ecology, (ii) system engineering concepts, (iii) development of future breakthrough technology as well optimization of present technology, (iv) process fundamentals (e.g. thermodynamics, separation physics, transport processes etc.), (v) product manufacture and design (for recycling), (vi) environmental legislation and (vii) technology as a basis for achieving sustainability within our present society.

The book discusses contentious issues such as the limits of recycling determined by physics, chemistry, economics and process technology, therefore providing the reader with a fundamental basis to understand and critically discuss the validity of environmental legislation. Furthermore, the 'Web of Metals' (i.e. the dynamic interconnection of metal and material cycles and product systems) will reveal that, if the application of environmental evaluation techniques such as material flow analysis, life cycle assessment etc. are not carried out on a sufficient theoretical basis, technological and economic understanding, analyses could lead to erroneous and in the end environmentally harmful conclusions.

The book is illustrated with many industrial examples embracing car and electronic consumer goods manufacturing and recycling, and the production and recycling of all major metals (e.g. steel, aluminium, copper, zinc, lead, magnesium, PGM's and PM's) and to an extent plastics. A complete section of the book is devoted to the recycling of light metals. Numerous colour figures and photos, plant and reactor data as well as software and computer models (running under Matlab's Simulink® and AMPL® as well as tools based on neural net technology (CSenseTM) are provided to give the reader the opportunity to investigate the various topics addressed in this book at various levels of depth and theoretical sophistication, providing a wealth of information, share-data and industrial know-how.

Finally, the book philosophically discusses how to harmonize the resource, life and technological cycles depicted by the figure on the cover to make a contribution to the sustainable use of resources and products.

* Material and Metal Ecology and the various modelling aspects to quantify this
* System modelling of recycling systems with applications in the automotive and consumer
goods sector
* Metallurgical metal recycling with applications in aluminium, supplemented with various modelling examples from thermodynamics, exergy, neural nets to CFD

The Phytochemical Society of North America held its forty-fourth annual meeting in Ottawa, Ontario, Canada from July 24-28, 2004. This year's meeting was hosted by the University of Ottawa and the Canadian Forest Service, Great Lakes Forestry Centre and was held jointly with the International Society of Chemical Ecology. All of the chapters in this volume are based on papers presented in the symposium entitled "Chemical Ecology and Phytochemistry of Forest Ecosystems". The Symposium Committee, Mamdouh Abou-Zaid, John T. Arnason, Vincenzo deLuca, Constance Nozzolillo, and Bernard Philogene, assembled an international group of phytochemists and chemical ecologists working primarily in northern forest ecosystems. It was a unique interdisciplinary forum of scientists working on the cutting edge in their respective fields. While most of these scientists defy the traditional labels we are accustomed to, they brought to the symposium expertise in phytochemistry, insect biochemistry, molecular biology, genomics and proteomics, botany, entomology, microbiology, mathematics, and ecological modeling.A collection of papers presented at the 44th Annual meeting of the Phytochemical Society of North AmericaRepresentation from a unique interdisciplinary forum of scientistsIncludes discussions on new genomics research in forest health

The Natural Radiation Environment Symposium (NRE VII), the Seventh in the NRE series, which commenced forty years ago in 1963 at Rice University Texas, was held in Rhodes (Greece) in May 2002. During the intervening four decades the research work presented at these NRE Symposia has contributed to a deeper understanding of natural radiation and in particular of its contribution to human radiation exposures.

It is clear from the quality and diversity of the 143 papers in this volume of Radioactivity in the Environment series that the study of the natural radiation environment is an active and continually expanding field of research. The papers in this volume fall into a number of main and topical research areas namely:

the measurement and behaviour of natural radionuclides in the environment
cosmic radiation measurement and dosimetry
the external penetrating radiation field at ground level
TENR (Technologically Enhanced Natural Radiation) and NORM (Naturally Occurring Radioactive Materials) studies
assessment of the health effects of radon
regulatory aspects of natural radiation exposures

In these papers the results of many new surveys of natural radionuclide levels in the environment and of improved methods of detection are described. While some of the natural radiation sources investigated are unmodified by human activity, many accounts are given here of exposures to natural sources which have been enhanced by technology. Such TENR and NORM exposures are shown to range from activities such as mining, oil and gas exploitation, the use of industrial by-products as building materials, to space travel to name but a few. In several cases quite high doses to some individuals are shown to occur. Accounts are given here of methods to prevent and reduce exposures to such sources.
