The study also shows traffic-related air pollution could be specifically responsible for up to 24% of the total number of cases.
An international team of researchers has used a newly developed model to assess the impact exposure to nitrogen oxides — gases that make up air pollution — has on the development of childhood asthma.
Their study, published today in Environment International, used a model that knits together four distinct models of traffic, emissions, atmospheric dispersion and health impact assessments in Bradford. This allowed the researchers to chart the full chain of impact — from the source of air pollution through the pathways in which it impacts children’s health.
The results indicate that up to 38% of all annual childhood asthma cases in Bradford may be attributable to air pollution. More specifically, the model estimates showed that 12% of the annual childhood asthma cases would be attributable to traffic related air pollution.
