Local exposure to traffic on a freeway (motorway) has serious adverse effects on children’s lung development, which could result in unhealthy lung function in later life, according to an article in The Lancet (30 January 2007) by James Gauderman of the University of Southern California.
Researchers studied the development of 3600 children from the age of 10 to 18. They found that children living within a radius of 500 metres of heavy traffic had reduced lung capacity at the age of 18. They also had an increased risk of developing cardiovascular problems as a result of exposure to traffic pollution. Read the article in The Lancet
