ntroduction:It is expected that about 600 stations for pollen andother biological particles in ambient air exist worldwide (Buters2014). However, currently no comprehensive information on pollenmonitoring sites is available as the map in the“Atlas of allergy”(Buters 2014) is already outdated and/or incomplete. In fact, in manycases no information, limited information, or false information onwho, where, what and...
Background: Allergies to grass pollen are the number one cause of outdoor hay fever. The human immune system reacts with symptoms to allergen from pollen. Objective: We investigated the natural variability in release of the major group 5 allergen from grass pollen across Europe. Methods: Airborne pollen and allergens were simultaneously collected daily with a volumetric spore trap and a high-volume cascade impa...
Exposure to allergens is pivotal in determining sensitization and allergic symptoms in individuals. Pollen grain counts in ambient air have traditionally been assessed to estimate airborne allergen exposure. However, the exact allergen content of ambient air is unknown. We therefore monitored atmospheric concentrations of birch pollen grains and the matched major birch pollen allergen Bet v 1 simultaneously acr...
