An NIEHS-funded study of children’s health and asthma showed that children who play an abundance of outdoor sports in areas where ozone levels are high may be three times more likely to develop asthma than children who do not take part in outdoor sporting activities. Researchers found there was no increased risk in areas where the ozone levels were low.
