Summary
Brief summary
We will determine the contribution of Plane Trees to the respiratory symptoms of inner-Sydney residents. We will measure the allergic symptoms of groups of patients over the Spring and Summer, while sampling air at 2 city locations and also specific locations related to exacerbations of symptoms (attacks) in individuals. The results of this study will help people manage their allergies, and provide information for policy-makers.
