It’s official: Traffic pollution can cause asthma in children

Researchers in Europe have confirmed scientifically what parents in traffic-congested Southern California have known anecdotally for years: Poor air quality associated with busy roads can cause asthma in children.

The study, which examined children’s health in 10 cities, concluded that 14% of chronic childhood asthma cases could be attributed to near-road traffic pollution. It is the first time that medical researchers have made such a direct link — previous studies stopped at saying that traffic pollution is known to trigger asthma, not cause it.
