Air Quality Monitoring
Ambient Air Quality affects everyone. Children often play outside during hot, muggy summer afternoons. Their lungs are still developing, and they breathe more rapidly and inhale more air pollution per pound of body weight than adults. On days when smog levels are high, these factors put children at increased risk for respiratory problems. Adults breathe about 20,000 times each day. During exercise or strenuous work, we breathe more often and draw air more deeply into our lungs. When we exercise heavily, we may breathe in up to ten times more air than we breathe when we are resting.
