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. 606 $aPediatric toxicology 606 $aPesticide residues in food$zUnited States 606 $aPesticides$xToxicology 606 $aInfant formulas$xContamination 606 $aFood contamination 615 0$aPediatric toxicology. 615 0$aPesticide residues in food 615 0$aPesticides$xToxicology. 615 0$aInfant formulas$xContamination. 615 0$aFood contamination. 676 $a615.9/54 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910960214803321 996 $aPesticides in the diets of infants and children$94354013 997 $aUNINA
