Identification of potential sources of airborne Olea pollen in the Southwest Ib...
Fernández-Rodríguez, Santiago; Skjøth, Carsten Ambelas; Tormo-Molina, Rafael; Brandao, R. M.; Caeiro, E.; Silva-Palacios, InmaculadaThis study aims to determine the potential origin of Olea pollen recorded in Badajoz in the Southwest of the Iberian Peninsula during 2009–2011. This was achieved using a combination of daily average and diurnal (hourly) airborne Olea pollen counts recorded at Badajoz (south-western Spain) and Évora (south-eastern Portugal), an inventory of olive groves in the studied area and air mass trajectory calculations c...
Grass Pollen Count and Grass group 5-allergen Release across Eight European Cou...
Buters, Jeroen M.; Albertini, Roberto; Annesi-Maesano, Isabella; Antunes, Celia M.; Berger, Uwe; Brandao, Rui M.; Cecchi, Lorenzo; Celenk, SevcanBackground: Grass pollen is considered to be the most important outdoor aeroallergen in Europe. The grass ‘pollen count’ is usually used as a proxy for exposure. However, HIALINE has shown that the birch and olive pollen count is not always congruent with allergen concentrations. We therefore simultaneously measured daily exposure to grass pollen and the concentration of group 5 major allergens across eight cou...
TEMPORAL AND SPATIAL DISTRIBUTION OF POACEAE POLLEN IN AREAS OF SOUTHERN UNITED...
Fernandez Rodriguez S.; Adams-Groom B.; Tormo-Molina, Rafael; Palacios, Silva; Brandao, R. M.; Caeiro, E.; Gonzalo-Garijo, A.; Smith MattOverall, longer Poaceae pollen seasons coincided with earlier pollen season start dates. Winter rainfall noticeably affects the intensity of Poaceae pollen seasons in Mediterranean areas, but this was not as important in Worcester. Weekly data from Worcester followed a similar pattern to that of Badajoz and Évora but at a distance of more than 1500 km and 4-5 weeks later.
Release of Bet v 1 from birch pollen from 5 European countries. Results from th...
Buters, Jeroen T.M.; Thibaudon, Michel; Smith, Matt; Kennedy, Roy; Rantio-Lehtimäki, Auli; Albertini, Roberto; Reese, Gerald; Weber, BernhardExposure 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 ac...
