According to the most comprehensive study ever conducted
on air pollution and children’s health, pollutants from vehicle emissions
and fossil fuels are causing chronic, adverse effects on lung development
in many children.
Data from the Children’s Health Study indicate that children who
live in polluted communities are more likely to have reductions in lung capacity
compared with those at low levels of exposure (N Engl J
Med. 2004;351:1057-1067). In this prospective study, researchers measured
lung function of 1759 fourth-grade children (whose average age was 10 years)
recruited from schools in 12 southern California communities. These children
had their lung function tested annually for 8 consecutive years, and researchers
tracked the levels of air pollutants in the children’s communities.
