The researchers .. focused their study on children who participated in active sports, which would require them to draw up to 17 times the "normal" amount of air sucked into the lungs of a child who was relatively inactive.

"..on days when air pollution levels are expected to be high, children should limit prolonged outdoor exertion." Read the full Study
