— -- Question:How does air pollution affect my risk of developing asthma?

Answer: The people at the biggest risk for developing asthma are children. And children may have an increased risk of asthma if they are exposed to large amounts of ozone and if they're exposed to things like tobacco smoke or diesel exhaust particles.
