Childhood Asthma and Exposure to Traffic and Nitrogen Dioxide

This study examines the association between traffic-related pollution and childhood asthma among 208 children in 10 communities in Southern California.

  • Results demonstrate an association between increased asthma and closer residential distance to a freeway, indicating that respiratory health in children is adversely affected by local exposures to outdoor Nitrogen Dioxide or other freeway-related pollutants.
  • The implications of these data are important and relevant because they strengthen emerging evidence that air pollution can cause asthma and that traffic-related pollutants are partly responsible for this association.
