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.

Interventions

This is a preliminary, prospective study to investigate the exposure of Sydney residents to bioaerosols associated with the Plane Tree (Platanus x hybrida).No drugs or teatments will be used. We will be observing symptoms of respiratory allergies, including rhinitis and asthma. Subjective symptom scores will be recorded, as well as self-administered peak flow tests. Participants will be observed for 3 months.
