Proximity to major roadways is a risk factor for airway hyper-responsiveness in adults
Canadian Respiratory Journal, 04/24/2012
Riley S et al. – In an adult population of patients attending an outpatient respiratory clinic in Hamilton, living close to major roadways was associated with an increased risk of moderate airway hyper–responsiveness. This correlation suggests that exposure to traffic emissions may provoke the pathology of airway hyper–responsiveness leading to variable airflow obstruction.
