Assessment of airborne Asteraceae pollen in Brisbane, Australia

Abstract

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

Análise da prospecção tecnológica por meio de revisão sistemática seguida de meta análise das patentes do gênero Baccharis

“…Entretanto, nenhum artigo científico sobre uso alimentar ou propriedades nutricionais do pólen de B. halimifolia foi encontrado. Mas, encontra-se na literatura, registros sobre a reação alérgica causada pelo pólen da espécie citada acima (GREEN, SIMPSON E DETTMANN, 2012;FRITO et al, 2016). A discussão sobre este assunto encontra-se adiante no tópico Saúde humana, farmacologia e cosméticos, sub tópico Oncologia, enfermidades autoimunes e alergologia.…”
