This book was released on 2000-07-13 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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. Feature: Presents a comprehensive look at all aspects of pesticide toxicology in one reference work. Benefit: Saves researchers time in quickly accessing the very latest definitive details on toxicity of specific pesticides as opposed to searching through thousands of journal articles. Feature: Clear exposition of hazard identification and dose response relationships in each chapter featuring pesticide agents and actions Benefit: Connects the experimental laboratory results to real-life applications in human health, animal health and the environment. Feature: All major classes of pesticide considered. Benefit: Provides relevance to a wider variety of researchers who are conducting comparative work in pesticides or their health impacts. Feature: Different routes of exposure critically evaluated. Benefit: Connects the loop between exposure and harmful affects to those who are researching the affects of pesticides on humans or wildlife.

Download or read book Pesticides Organic Contaminants and Pathogens in Air written by James N. Seiber and published by CRC Press. This book was released on 2021-10-07 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The air is an important but largely unrecognized source of contaminant fate in the environment, including transport of pesticides and contaminants to nontarget areas and exposures for people and wildlife. This book summarizes and places in perspective the potential transport, transformation, and health implications of pesticides and contaminants in air, including the air we breathe. It delves into the hypothesis that the atmosphere is the most significant environmental compartment affecting the overall transport and fate of many classes of environmental contaminants. The authors draw parallels between sampling, analysis, and impact of airborne toxics and particulate matter with the COVID-19 pandemic. Airborne viruses and fine particulate matter, which are of similar size, have remarkable parallels in how they are transmitted and accumulated in the respiratory tract. FEATURES Assesses exposures of people and wildlife to airborne chemicals Includes case study applications, with relevant data summarized for pesticides and contaminants in air Discusses approaches to modeling pesticides’ and contaminants’ dispersion and fate in air Includes an assessment of the physicochemical properties of pesticides and contaminants that influence sampling and atmospheric mobility and fate The authors are global experts in air contaminant research, and this book is well organized and helpful for people interested in regulatory, health, and other topics related to pesticides and contaminants in air. James N. Seiber is a Professor Emeritus at the University of California, Davis. Thomas M. Cahill is an Associate Professor in the School of Mathematical and Natural Sciences at Arizona State University.

Book excerpt: A “lively, comprehensive, and . . . definitive account of organic food’s rise” from a “first-rate business journalist” (Michael Pollan). Who would have thought that a natural food supermarket could have been a financial refuge from the dot-com bust? But it had. Sales of organic food had shot up about 20 percent per year since 1990, reaching $11 billion by 2003 . . . Whole Foods managed to sidestep that fray by focusing on, well, people like me. Organic food has become a juggernaut in an otherwise sluggish food industry, growing at twenty percent a year as products like organic ketchup and corn chips vie for shelf space with conventional comestibles. But what is organic food? Is it really better for you? Where did it come from, and why are so many of us buying it? Business writer Samuel Fromartz set out to get the story behind this surprising success after he noticed that his own food choices were changing with the times. In Organic, Inc., Fromartz traces organic food back to its anti-industrial origins more than a century ago. Then he follows it forward again, casting a spotlight on the innovators who created an alternative way of producing food that took root and grew beyond their wildest expectations. In the process he captures how the industry came to risk betraying the very ideals that drove its success in a classically complex case of free-market triumph.

Book excerpt: Assessing Exposures and Reducing Risks to People from the Use of Pesticides will focus on practices that have been developed in the past 10 years marked from the passage of the Food Quality Protection Act and other pertinent legislation (eg the Clean Air Act Amendments), which deal all, or in part with reducing risks associated with pesticides.
