Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.
The essential, cornerstone book of modern environmentalism is now offered in a handsome 40th anniversary edition which features a new Introduction by activist Terry Tempest Williams and a new Afterword by Carson biographer Linda Lear.
Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.
Neurotoxicity of Pesticides, Volume Four, in this comprehensive serial addresses contemporary advances in neurotoxicology of pesticides by providing authoritative review articles on key issues in the field. Edited by leading subject experts, topics of note in this new release include Organophosphates, OPs, Nerve agents, Pyrethroids, Neonicotinoids and Formamidines, among others.
In this fascinating book, Graham Matthews takes the reader through the history of the development and use of chemicals for control of pests, weeds, and vectors of disease. Prior to 1900 only a few chemicals had been employed as pesticides but in the early 1940s, as the Second World War raged, the insecticide DDT and the herbicide 2-4-D were developed. These changed everything. Since then, farmers have been using a growing list of insecticides, herbicides and fungicides to protect their crops. Their use has undoubtedly led to significant gains in agricultural production and reduction in disease transmission, but also to major problems: health concerns for both users of pesticides and the general public, the emergence of resistance in pest populations, and environmental problems. The book examines the development of legislation designed to control and restrict the use of pesticides, the emergence of Integrated Pest Management (IPM) and the use of biological control agents as part of policy to protect the environment and encourage the sustainable use of pesticides. Finally, the use of new technologies in pest control are discussed including the use of genetic modification, targeted pesticide application and use of drones, alongside basic requirements for IPM such as crop rotations, close seasons and adoption of plant varieties with resistance to pests and diseases.
Concern about health effects from exposure to pesticides in foods is growing as scientists learn more about the toxic properties of pesticides. The Delaney Clause, a provision of the Food, Drug and Cosmetic Act, prohibits tolerances for any pesticide that causes cancer in test animals or in humans if the pesticide concentrates in processed food or feeds. This volume examines the impacts of the Delaney Clause on agricultural innovation and on the public's dietary exposure to potentially carcinogenic pesticide residues. Four regulatory scenarios are described to illustrate the effects of varying approaches to managing oncogenic pesticide residues in food.
This fascinating new volume provides a comprehensive yet concise overview of the chemical aspects of some of the major innovations and changes that occurred during the 20th century, relating chemical structures and properties to real-life applications. Developed for a course taught by the author for several years at UVA, the author covers the important and consequential developments in chemistry and explains their everyday, real-life applications. These include such topics as consumer products, fossil fuel use, polymers, agriculture, food production, nutrition, explosives, and drugs. The section Molecular Biology and Its Applications includes examples of the application of biotechnology and genetic engineering.
This sweeping history reveals how the use of chemicals has saved lives, destroyed species, and radically changed our planet: “Remarkable . . . highly recommended.” —Choice In The Chemical Age, ecologist Frank A. von Hippel explores humanity’s long and uneasy coexistence with pests, and how the battles to exterminate them have shaped our modern world. He also tells the captivating story of the scientists who waged war on famine and disease with chemistry. Beginning with the potato blight tragedy of the 1840s, which led scientists on an urgent mission to prevent famine using pesticides, von Hippel traces the history of pesticide use to the 1960s, when Rachel Carson’s Silent Spring revealed that those same chemicals were insidiously damaging our health and driving species toward extinction. Telling the story in vivid detail, von Hippel showcases the thrills—and complex consequences—of scientific discovery. He describes the creation of chemicals used to kill pests—and people. And, finally, he shows how scientists turned those wartime chemicals on the landscape at a massive scale, prompting the vital environmental movement that continues today.
