Chlorinated Insecticides Technology And Application

This definitive and most detail work ever to have been published, devoted exclusively to the chemistry and biology of chlorinated insecticides, comes from the authoritative pen of a leading investigator in this field. It should serve for many years to come as the prime reference source both for instructional and research purposes, for it not only delineates that which is known about this valuable class of compounds, but also emphasises those important biological and ecological areas in which our knowledge is still much too sketchy and in which further investigation may be expected to uncover facts of great interest and wide applicability.

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.

Volume I of Chlorinated Insecticides considered the technology of these compounds in a historical context, tracing their development up to the resent time. The accounts of the numerous applications in insect control given there provide a link with Volume II in that they pose many questions about the interactions of these compounds with living organisms. Some of these questions will be examined in the Subsequent Chapters of this book.
