Diurnal trends in reported poisonings.

Review of the Duke Poison Control Center records for 1977 revealed an evening peak for preschool poisonings, while older victims had a late night maximum. When the reports were stratified by poisoning agent, both age groups showed diurnal trends for internal medicines, plants, household products, and pesticides. In addition, preschool victims had temporal variation in poisonings with soaps, petroleum compounds, external medicines, and cosmetics.
