ExpoKids: Children’s Aggregate Exposure Visualization Tool

  • ExpoKids Home
  • Background
  • Online Application
  • Tools and Resources

ExpoKids is a tool that helps scientists and researchers explore a diverse set of children’s health risk assessment and management inquiries by visually depicting the impact of aggregate exposure to contaminants via the oral route to children throughout their lives.

Aggregate exposure The combined exposure of an individual (or defined population) to a specific agent or stressor via relevant routes, pathways, and sources. Total exposure can include exposure through multiple routes (e.g., dermal, inhalation, and ingestion). assessments are often important in children’s health risk assessments because children’s unique behaviors and physiology can alter chemical exposure rates across different media, routes, and lifestages relative to the adult lifestage. Further, relative to adults, children exhibit increased susceptibility to some chemical exposures during development.
