Book Description
Pyrethrum: the Natural Insecticide covers the papers presented at the 1972 ""International Symposium on Recent Advances with Pyrethrum the Natural Insecticide"" held in conjunction with the American Institute of Biological Sciences Silver Anniversary Meeting at the University of Minnesota, Minneapolis. It deals with all aspects of pyrethrum, including its history, production, chemistry, biochemistry, toxicology, pharmacology, and agricultural applications. The introductory part addresses the early history of pyrethrum, its recognition as a modern insecticide, and its worldwide production. The chemistry and biochemistry parts discuss the composition, isolation, structure, synthesis, biosynthesis, metabolism, and action on enzyme systems of natural pyrethrins extracted from pyrethrum flower. The book also examines the toxicology of pyrethrum and its constituents to mammals, fish, and wildlife, as well as tests for possible teratogenic, carcinogenic, mutagenic, and allergenic activities. Finally, it discusses the domestic and agricultural applications of pyrethrum. Considering its desirable features, researchers find pyrethrum unsurpassed by any type of synthetic organic insecticide and even by the best synthetic analogs or pyrethroids.

Book Description
Nature has often provided valuable molecules either as lead compounds or for use in the fight against pests. Though a number of conference proceedings deal with the control of insects using natural products, there is no comprehensive account of what materials have been studied and what results have been obtained. Examining the material scattered across various disciplines, this book meets a recognized need by consolidating this information in one volume. The first section of the book covers chemistry and biological activity of major classes of naturally occurring pesticides, including the development of more potent insecticides based on natural lead-in structures. The second section consists of monographs on each compound by product.

Book Description
This handbook series includes several naturally occurring chemicals that exhibit biological activity. These chemicals are derived from plants, insects, and several microorganisms. Volume I of this series is covers the theory and practice of the strategies for pest control and methods for detection.Moreover, it presents extensive tables that provide the information you need to select the most appropriate bioassay for a particular plant growth regulator or hormone. In addition to the chapters on bioassays, Volume I provides a solid introduction to the theory and practice of natural pesticide use, including in-depth discussions of integrated management systems for weed and pest control, the state-of-the-art use of computers in pest management, and allelochemicals as natural protection. Guidelines on toxicological testing and EPA regulation of natural pesticides are also detailed.

Book Description
'Environmental forensics' is a combination of analytical and environmental chemistry, which is useful in the court room context. It therefore involves field analytical studies and both data interpretation and modelling connected with the attribution of pollution events to their causes. Recent decades have seen a burgeoning of legislation designed to protect the environment and, as the costs of environmental damage and clean-up are considerable, not only are there prosecutions by regulatory agencies, but the courts are also used as a means of adjudication of civil damage claims relating to environmental causes or environmental degradation. As a result is the increasing number of prosecutions of companies who have breached regulations for environmental protection and in civil claims relating to harm caused by excessive pollutant releases to the environment. Such cases can become extremely protracted as expert witnesses provide their sometimes conflicting interpretations of environmental measurement data and their meaning. It is in this context that environmental forensics is developing as a specialism, leading to greater formalisation of investigative methods which should lead to more definitive findings and less scope for experts to disagree. Now a significant subject in its own right, at least one journal devoted to the field and a number of degree courses have sprung up. As a result of the topicality and rapid growth of the subject area, is the publication of this book - the 26th volume in the highly acclaimed Issues in Environmental Science and Technology Series. This volume contains authoritative articles by a number of the leading practitioners across the globe in the environmental forensics field and aims to cover some of the main techniques and areas to which environmental forensics are being applied. The content is comprehensive and describes a number of the key areas within environmental forensics - topics covered by the authors include: - Source identification issues - Microbial techniques - Metal contamination and methods of assigning liability - The use of isotopes to determine sources and their applications - Molecular biological methods - Hydrocarbon fingerprinting techniques - Oil chemistry and key compound identification - The emerging role of environmental forensics in groundwater pollution Additionally, the volume considers specific pollutants and long-lived pollutants of groundwater such as halocarbons which have presented particular problems and which are described in some depth, as well as the way in which chemical degradation processes can lead to compositional changes which provide valuable information. The book provides a comprehensive overview of many of the key areas of environmental forensics written by some of the leading experts in the field. It will be both of specialist use to those seeking expert insights into the field and its capabilities as well as of more general interest to those involved in both environmental analytical science and environmental law.

Book Description
Volume I tells you how to perform bioassays for plant and insect hormones, regulators, and pathogens. Moreover, it presents extensive tables that provide the information you need to select the most appropriate bioassay for a particular plant growth regulator or hormone. In addition to the chapters on bioassays, Volume I provides a solid introduction to the theory and practice of natural pesticide use, including in-depth discussions of integrated management systems for weed and pest control,k the state-oof-the-oart use of computers in pest management, and allelo-chemicals as natural protection.
