Book Description
Excerpt from Concentrations of Methyl Bromide Lethal to Insects in Grain: Laboratory Studies of Sorption Rates and Effects of Concentrations on Rice Weevil and Confused Flour Beetle Thirty individuals of each species were placed in the test cages for the adult insects. Separate cages were filled with 11 cubic centimeters of the appropriate kind of grain infested with immature rice weevils. The insect test cages were probed into the grain-filled cylinders through holes located in the cylinder walls halfway between the two ends.

Book Description
Methyl bromide is gaseous pesticide used to fumigate soil, crops, commodity warehouses, and commodity-shipping facilities. Up to 17 million pounds of methyl bromide are used annually in California to treat grapes, almonds, strawberries, and other crops. Methyl bromide is also a known stratospheric ozone depleter and, as such, is scheduled to be phased out of use in the United States by 2005 under the United Nations Montreal Protocol. In California, the use of methyl bromide is regulated by the Department of Pesticide Regulation (DPR), which is responsible for establishing the permit conditions that govern the application of methyl bromide for pest control. The actual permits for use are issued on a site-specific basis by the local county agricultural commissioners. Because of concern for potential adverse health effects, in 1999 DPR developed a draft risk characterization document for inhalation exposure to methyl bromide. The DPR document is intended to support new regulations regarding the agricultural use of this pesticide. The proposed regulations encompass changes to protect children in nearby schools, establish minimum buffer zones around application sites, require notification of nearby residents, and set new limits on hours that fumigation employees may work. The State of California requires that DPR arrange for an external peer review of the scientific basis for all regulations. To this end, the National Research Council (NRC) was asked to review independently the draft risk characterization document prepared by DPR for inhalation exposure to methyl bromide. The task given to NRC's subcommittee on methyl bromide states the following: The subcommittee will perform an independent scientific review of the California Environmental Protection Agency's risk assessment document on methyl bromide. The subcommittee will (1) determine whether all relevant data were considered, (2) determine the appropriateness of the critical studies, (3) consider the mode of action of methyl bromide and its implications in risk assessment, and (4) determine the appropriateness of the exposure assessment and mathematical models used. The subcommittee will also identify data gaps and make recommendations for further research relevant to setting exposure limits for methyl bromide. This report evaluates the toxicological and exposure data on methyl bromide that characterize risks at current exposure levels for field workers and nearby residents. The remainder of this report contains the subcommittee's analysis of DPR's risk characterization for methyl bromide. In Chapter 2, the critical toxicological studies and endpoints identified in the DPR document are evaluated. Chapter 3 summarizes DPR's exposure assessment, and the data quality and modeling techniques employed in its assessment are critiqued. Chapter 4 provides a review of DPR's risk assessment, including the adequacy of the toxicological database DPR used for hazard identification, an analysis of the margin-of-exposure data, and appropriateness of uncertainty factors used by DPR. Chapter 5 contains the subcommittee's conclusions about DPR's risk characterization, highlights data gaps, and makes recommendations for future research.

Book Description
Written by international experts in the field, this book sets outthe scientific arguments for and against the use of methyl bromidewhich is both naturally occurring and also a man-made productbelieved to have played a significant role in the depletion of theozone layer. Methyl bromide is a widely used fumigant in agriculture,horticulture and the preservation of structural materials. The fateof this natural and man-made chemical is the focus of much fiercedebate with scientific, political, social, environmental andeconomic arguments for and against the production and use of thischemial. This book does not set out to convince the reader of apredetermined viewpoint. Its purpose is to set out the scientificdebate covering the major relevant fields including agriculture,atmospheric chemistry, oceanography, environmental sciences,chemistry, biology and toxicology, as well as two chapters onpotential alternatives to methyl bromide. The authors who havecontributed to this book are all experts who have played pivotalroles in the international debate on methyl bromide.

Book Description
Therapeutic, Probiotic and Unconventional Foods compiles the most recent, interesting and innovative research on unconventional and therapeutic foods, highlighting their role in improving health and life quality, their implications on safety, and their industrial and economic impact. The book focuses on probiotic foods, addressing the benefits and challenges associated with probiotic and prebiotic use. It then explores the most recently investigated and well-recognized nutraceutical and medicinal foods and the food products and ingredients that have both an impact on human health and a potential therapeutic effect. The third and final section explores unconventional foods and discusses intriguing and debated foods and food sources. While research has been conducted on the beneficial biological effects of probiotics and therapeutic food, the use of these foods remains controversial. To overcome the suspicion of the use of alternative, homeopathic and traditional products as therapy, this book reveals and discusses the most recent and scientifically sound and confirmed aspects of the research. - Compiles the most recent, interesting and innovative research on unconventional and therapeutic foods - Highlights the role of unconventional and therapeutic foods in improving health and life quality - Discusses the implications of unconventional and therapeutic foods on safety - Presents the industrial and economic impact of unconventional and therapeutic foods

Book Description
The Handbook of Pesticide Toxicology is a comprehensive, two-volume reference guide to the properties, effects, and regulation of pesticides that provides the latest and most complete information to researchers investigating the environmental, agricultural, veterinary, and human-health impacts of pesticide use. Written by international experts from academia, government, and the private sector, the Handbook of Pesticide Toxicology is an in-depth examination of critical issues related to the need for, use of, and nature of chemicals used in modern pest management. This updated 3e carries on the book's tradition of serving as the definitive reference on pesticide toxicology and recognizes the seminal contribution of Wayland J. Hayes, Jr., co-Editor of the first edition. - Presents a comprehensive look at all aspects of pesticide toxicology in one reference work. - Clear exposition of hazard identification and dose response relationships in each chapter featuring pesticide agents and actions - All major classes of pesticide considered - Different routes of exposure critically evaluated
