Air pollution from city traffic raises the risk of asthma attacks in children that require a visit to the hospitals emergency service.
Air pollution from city traffic raises the risk of asthma attacks in children that require a visit to the hospital's emergency service.
Certain outdoor air pollutants trigger asthma in children. To pinpoint which components of pollution play the biggest role in making asthma worse, researchers examined the medical records of American children 5 to 17 years old who had been treated in Atlanta-area emergency rooms from 1993 to 2004 because of asthma attacks. Data was gathered from more than 91,386 asthma-related visits to 41 Metropolitan Atlanta hospitals. The researchers analysed connections between the visits and daily data on the levels of 11 different pollutants.
It was found signs that ozone worsens asthma and the components of pollution that comes from combustion engines, such as those in cars and trucks, were also linked to serious asthma problems in children.
It was concluded that even at relatively low ambient concentrations, ozone and primary pollutants from traffic sources independently contribute to the burden of emergency department visits for asthma in children.
