Child Safety: Air Pollution - Topic Overview

Smog and particulate matter (such as pollen, soot, and dust) are examples of air pollution. Children's lungs are especially sensitive to the harmful effects of air pollution, because they breathe rapidly and inhale a high concentration of pollution relative to their weight.

Use care when you take your young child outdoors, especially for physical activities. When children exercise, they breathe more heavily than normal. Also, they breathe more through their mouths than their noses. This allows pollution to be inhaled more deeply into the lungs where it can cause permanent damage.
