Traffic-related air pollution has been associated with adverse cardiorespiratory effects, including increased asthma prevalence. However, there has been little study of effects of traffic exposure at school on new-onset asthma. A study published in the July 2010 issue of Environmental Health Perspectives evaluated the relationship of new-onset asthma with traffic-related pollution near homes and schools. Asthma risk increased with modeled traffic-related pollution exposure from roadways near homes and near schools. Researchers concluded that traffic-related pollution exposure at school and homes may both contribute to the development of asthma. To read the complete study, click here.
