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...
Airborne olive pollen counts are not representative of exposure to the major ol...
Galán C.; Antunes, C.M.; Brandao, R. M.; Torres, C.; Garcia-Mozo, H.; Caeiro, E.; R. Ferro; Prank, M.; Sofiev, M.; R. Albertini; U. Berger; L. CecchiPollen is routinely monitored, but it is unknown whether pollen counts represent allergen exposure. We therefore simultaneously determined olive pollen and Ole e 1 in ambient air in C ordoba, Spain, and Evora, Portugal, using Hirst-type traps for pollen and high-volume cascade impactors for allergen. Pollen from different days released 12-fold different amounts of Ole e 1 per pollen (both locations P < 0.001)....

Caeiro, E.; Lopes, M.L.; Gaspar, A.; Todo-Bom, A.; Oliveira, J.F.; Nunes, C.; Mario Morais-Almeida; Trindade, Costa; Brandao, R. M.Introdução: O pólen da família das Poaceae (gramíneas) é uma das principais fontes de aeroalergénios no mundo, particularmente na Europa Mediterrânica. Representa, por isso, um importante factor de risco de asma, rinite e/ou conjuntivite alérgica e constitui a principal causa de polinose em Portugal. Objectivo: Analisar a variação intradiária das concentrações de pólen de gramíneas na atmosfera das 5 estações d...

Santiago Férnandez Rodríguez; Skjøth, Carsten Ambelas; Tormo-Molina, Rafael; Brandao, R. M.; Caeiro, E.; M. Smith; Silva-Palacios, I.Regional scale transport of olive pollen can result in increased nighttime concentrations of this important aeroallergen. This could be particularly important in Mediterranean countries where people can be outdoors during this time due to climate and lifestyle. Such studies are valuable for allergy sufferers and health care professionals because the information can be incorporated into forecasts, the outputs of...

Santiago Férnandez Rodríguez; Skjøth, Carsten Ambelas; Tormo-Molina, Rafael; Brandao, R.M.; Caeiro, E.; Silva-Palacios, I.; Gonzalo-Garijo, A.; M. SmithThis 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 (southwestern Spain) and Évora (southeastern Portugal), an inventory of olive groves in the studied area and air mass trajectory calculations com...
Modelling of Symptoms in Patients with Pollinosis in the Alto Alentejo Region
Afonso, F.; Caeiro, E.; Brandao, R. M.; Lopes, M.L.; Oliveira, M.M.The syrnptorns of pollen allergy by patients with pollinosis are the target of this study. Patients are frorn the region of Évora, and clinical data were collected at the Hospital of the Holy Spirit in Évora. The data collected is related to the years 2001-2007 for the rnonths of March to June. The syrnptorns exhibited by patients, whose condition was deterrnined by allergological test, were daily recorded over...
