Assessment of airborne Asteraceae pollen in Brisbane, Australia

摘要: In the southern hemisphere, airborne prevalence and seasonal distribution of Asteraceae pollen are poorly characterized. this study, we assessed longitudinal using an historic aerobiological dataset. The influence weather parameters on derived from species was additionally explored. collected a static Burkard 7-day spore trap during 5-year (June 1994–May 1999) aerometric surveillance program in Brisbane, Australia. Two discrete intervals were identified each sampling year. first interval (September October) consisted small quantities unidentifiable pollen. second (March April) characterized by highest concentrations that predominantly Baccharis halimifolia. Associations between daily temperature observed results study demonstrated B. halimifolia, invasive weed introduced late nineteenth century, continue to be environment Brisbane. Given public health burden associated with personal exposure other geographic locations, future Australian-based clinical studies should characterize contribution pollen, particular allergic sensitization respiratory morbidity.
