Background The aetiology of allergic respiratory disease in children is not yet fully
understood. Environmental factors are believed to play a major part. The amount of green …

The world's most severe thunderstorm asthma event occurred in Melbourne, Australia on 21
November 2016, coinciding with the peak of the grass pollen season. The aetiological role …

Aeroallergens or inhalant allergens, are proteins dispersed through the air and have the
potential to induce allergic conditions such as rhinitis, conjunctivitis, and asthma. Outdoor …

Pollen grains significantly contribute to the aerosol population, and levels are predicted to
increase in the future. Under humid atmospheric conditions, pollen grains can rupture …

Pollen grains emitted from vegetation can release subpollen particles (SPPs) that contribute
to the fine fraction of atmospheric aerosols and may act as cloud condensation nuclei …

Within the last years pollen grains have gained increasing attention due to their cloud-
forming potential. Especially the discovery that ice nucleating macromolecules (INMs) or …

In November 2016, an unprecedented epidemic thunderstorm asthma event in Victoria,
Australia, resulted in many thousands of people developing breathing difficulties in a very …

The drivers affecting the Pollen Allergen Potency (PAP, amount of allergen released per
pollen) are sparsely known. Betula and Poaceae airborne pollen are the two main allergenic …

Terrestrial ecosystems can influence atmospheric processes by contributing a huge variety
of biological aerosols (bioaerosols) to the environment. Several types of biological particles …
