“…Parietaria pollen grains have been identified as allergenic in many studies, while Urtica pollen grains are considered by most authors to be slightly allergenic. The prevalence of sensitivity to Parietaria in Spain varies from 3.5% in Barcelona to 12% in Vigo (March et al 1993;Belmonte et al 1998;Botey et al 1999). In inland Andalusia, Parietaria is reportedly responsible for 2.5% of pollen allergies (Domínguez-Vilches et al 1993), although this figure is higher in coastal areas, mainly along the Mediterranean coast.…”

Comparison of airborne herb pollen types in Córdoba (Southwestern Spain) and Poznan (Western Poland)

et al. 2009

This study sought to compare airborne pollen counts for a number of common herbaceous species (Plantago, Chenopodiaceae-Amaranthaceae, Rumex, and Urticaceae) in two cities with differing weather conditions, Córdoba (Southwestern Spain) and Poznan (Western Poland). Pollen seasons for these species were studied from 1995 to 2005. Aerobiological sampling was performed using a Hirst type 7-day spore trap, in accordance with the procedure developed by the European Aerobiology Network. A Spearman correlation test was used to test for correlations between meteorological parameters and daily airborne pollen counts. The Spearman correlation test and the Wilcoxon signed ranks test were also used to compare mean daily pollen counts for the two study sites. In Córdoba, the pollen season generally started around two months earlier than in Poznan, and also lasted longer. These findings were attributed to the presence of a larger number of species in Córdoba, with overlapping pollen seasons, and also to more favorable weather conditions. Trends in pollen season start dates were fairly stable over the study period, with a slight tendency to delayed onset in Córdoba and a modest advance in start date in Poznan. The pollen season end date also remained reasonably stable over the study, with only a slight tendency for the season to end earlier in Córdoba and later in Poznan. A clear trend towards declining annual pollen counts was recorded over the study period for all pollen types in both cities.

“…Northwest Spain, between 4% and 12% skin sensitisation to Quercus pollen has been reported among pollen-allergy sufferers (Belmonte, Roure, & March, 1998;Ferreiro, Núñez, Rico, Soto, & López, 1998). Symptoms are often recorded over prolonged periods, due both to the overlapping of flowering in the various species present in the environment and cross-reactivity with the pollen of Alnus, Betula, Castanea, Olea and Poaceae (Ickovic & Thibaudon, 1991).…”

Use of Quercus ilex subsp. ballota phenological and pollen-production data for interpreting Quercus pollen curves

2007

Although aerobiological data are often used in phenological research as an indicator of flowering, airborne pollen concentrations are influenced by a number of factors that could affect pollen curves. This paper reports on a study of various aspects of reproductive biology in Q. ilex subsp. ballota, together with environmental factors influencing pollen release and transport, with a view of achieving reliable interpretation of Quercus pollen curves in Ourense (NW Spain). Aerobiological data were recorded from 2002 to 2004 at two sites in the province of Ourense. From 1st February to the end of the flowering period, phenological observations were carried out on 19 trees from the Q. ilex subsp. ballota population found in the Ourense area. Pollen production was calculated for the same trees. The chilling and heating requirements for triggering development were also calculated. The mean flowering period lasted 11-15 days. Reduced pollen output per catkin and, especially, a reduced number of catkins per tree in 2003 and 2004, prompted a marked decline in overall pollen production. Major differences observed in Q. ilex subsp. ballota pollen curves were attributed to the considerable influence both of weather conditions during pollination and pollen production. In years with high pollen production and weather conditions favouring pollen release, Q. ilex subsp. ballota contributed almost 10% to the total Quercus pollen curve. Around 20% of the pollen trapped was captured before or after flowering periods.

“…Quercus, Parietaria, Castanea, Oleaceae and Poaceae (Ickovic & Thibaudon 1991). Despite the relative scarcity of olive trees in Northwest Spain, skin sensitisation to Olea pollen is detected in around 4 -12% of pollen-allergy sufferers (Arenas et al 1996, Belmonte et al 1998, Ferreiro et al 1998, Dopazo 2001. Further research into this species, and particularly into the onset of flowering and the amount of airborne pollen grains, is thus of interest.…”
