Air pollution from trucks and low-quality heating oil may explain childhood asthma hot spots
Date:3/27/2012

ty Earth Observatory . "These fuels produce more byproducts of incomplete combustion than cleaner oil or natural gas and contribute substantially to air pollution. Buildings that burn dirty oil are unevenly distributed throughout the city, which could help explain disparities in health."

The research team collected air samples from inside the homes of 240 7- and 8-year-old children from middle-income neighborhoods throughout New York City. These children also took breathing tests to measure exhaled nitric oxide, an indicator of lung inflammation.

"Airway inflammation plays an important role in the development of asthma and can contribute to more frequent symptoms among children with the disease," says study lead author Alexandra Cornell, MD, assistant professor in pediatrics at Dartmouth Medical School and previously a pediatric pulmonology fellow at Columbia University Medical Center/NewYork-Presbyterian Hospital. "Children in this study with higher black carbon in the air of their homes had higher exhaled nitric oxide, suggesting that they were at greater risk for asthma exacerbations. That this increased risk comes from air pollution lends weight to New York City's efforts to improve air quality, including phasing out the use of dirty oil, which is a large contributor to local air pollution.
