Facts You Should Know
Children breathe in a greater volume of air than adults relative to their body size.
Children's organs and respiratory, immune and neurological systems are still developing.
Children are much closer to the ground, and as a result, breathe in more of the heavier airborne chemicals than do adults.
Infants and young children breathe through their mouths, more so than do adults, which increases their risk of pulmonary exposure to particulates and fibers, that would otherwise be filtered out in the nose.
Children have a higher heart rate than adults, which allows substances that are absorbed into the blood to permeate tissues faster.
