摘要：Environmental exposures in children may occur through many routes, including diet, air, and the ingestion of various nonfood items such as medications and household materials. This article focuses on dietary exposure, but it does highlight the importance of considering other routes of exposure when assessing exposure in children. It presents many of the findings in the two recent reports, Pesticides in the Diets of Infants and Children and Science and Judgment in Risk Assessment of the National Academy of Sciences (NAS)/National Research Council (NRC). Diet is an important source of exposure for children to potential carcinogens. The trace quantities of chemicals present on or in foodstuffs are termed residues. In addition, there are substances that children may be exposed to in air and water that should be considered in a total exposure analysis. To minimize exposure of the general population to chemical residues in food, water, and air, the U.S. government has instituted regulatory controls. These are intended to limit exposures to residues while ensuring an abundant and nutritious food supply, and safe drinking water and air. The legislative framework for these controls was established by the Congress through various local and state laws and such federal laws as the Insecticide, Fungicide, and Rodenticide Act (FIFRA), the Federal Food, Drug, and Cosmetic Act (FFDCA), the Safe Drinking Water Act (SDWA), and the Clean Air Act (CAA). This article summarizes current approaches to assessing exposure and susceptibility in children. Full text Full text is available as a scanned copy of the original print version.
