What do you think about when you hear the word “Environment?”
Our Environment Opportunity
Objectives: To learn about • How and why children are more susceptible to environmental exposures than adults • Why individuals / institutions should take steps to protect children from environmental hazards
What’s the difference? Toxicity Exposure How much? How bad? TIMING Susceptibility Lifestage RISK

Safe Unsafe
A Child’s Environment Is All Around Them • Eating • Drinking • Breathing • Touching
Windows of Vulnerability in Development Differences in Physiology Differences in Behaviors Children Are Not Little Adults Children’s Increased Vulnerability
Exposure Differences : PhysiologyIncreased Exposures Relative to Adults • Pound for pound, kids • breathe more air than adults • drink more water than adults • eat more food than adults • have increased surface area to body mass ratio relative to adults • May also have different metabolism routes, speeds due to enzyme availability or activity
How many twelve ounce drinks/day would an adult male need to consume in order to take in proportionately as much as an infant? • 5 • 10 • 20 • 35 • 50
Exposure Differences : BehaviorsIncreased Exposures Relative to Adults • Closer to the ground • Diet and eating habits differ • Newborns - breast milk or formula • Infants / Toddlers - more fruit and milk products • “Fussy Eaters” abound • “Grazing” is common
How many times more apples does an average child eat compared to an adult, not accounting for child’s smaller size? • 3 • 7 • 11 • 15 • Adults eat more apples than children
Exposure Differences : BehaviorsIncreased Exposures Relative to Adults • Engage in more potentially high-risk behavior • increased hand contact with “stuff” • increased mouthing behaviors • more time spent outdoors
Why We Care: Indoor / Outdoor Environmental Pollutants • Can lead to neurodevelopmental disabilities, e.g. Mental retardation, ADHD, Poor Impulse Control • Can cause or worsen respiratory diseases • Can increase risk of cancer • Can affect hormone systems • Implicated in adult diseases • May affect multiple generations

Estrogenic agents and obesity Healthcare costs due to Obesity ~ $190 Billion / year. If only 1% attributable to environmental exposures, accounts for nearly $2 Billion
Region 5 Center for Children’s Environmental Health866-967-7337, 312-864-5526 • Co-funded by EPA and ATSDR • Serves as a Regional resource to: • evaluate, treat and prevent environmental illness in children • train pediatricians and others in environmental health issues • promote children’s environmental health in communities
Framework for Rest of Today’s Sessions • Children are more susceptible to environmental exposures than adults • Indoor environments account for large % of childhood exposures • Individual / Institutional opportunities to reduce • Toxicity • Exposure Be Open to New Ideas / New Approaches!
