This report examines the extensive presence of pesticide contamination in the environment and its impact on children. Chapters 1 and 2 review evidence that when pesticides are used indoors or out in other comparable settings, unavoidable contamination occurs, even when products are used according to label directions. Chapter 3 explains that people can be exposed to pesticides by breathing vapors or dusts, absorbing residues through their skin or eyes, or ingesting residues, granules or baits through hand-to-mouth contact. Chapter 4 documents actual school pesticide exposure incidents and presents the symptoms experienced. Chapter 5 presents recommendations for parents, schools, states, and the federal government. An appendix contains summary narratives describing 98 selected school pesticide exposure incidents that have occurred in the United States since 1986. Accompanying this report is "Unintended Casualties: Five Children Whose Lives Were Profoundly Affected by Pesticide Exposures at School," which contains five stories of children whose health and lives were affected in profound and permanent ways by pesticide exposures at school. (Contains 98 references). (GR)
