“…Wind speed is associated both with the primary emission of pollen from the anthers (Emecz, 1962;Lu et al, 2005) and with secondary emission through resuspension (Sánchez Mesa et al, 2003;Sehmel, 1980); however, no significant difference in wind speed was found between the three periods of the grass pollen season. Norris-Hill (1999) proposed that the timing of diurnal grass pollen peaks may be related to the time elapsed since rainfall due to the availability of pollen for resuspension.…”

Seasonal variation in diurnal atmospheric grass pollen concentration profiles

Abstract. In this study, the diurnal atmospheric grass pollen concentration profile within the Danish city of Aarhus was shown to change in a systematic manner as the pollen season progressed. Although diurnal grass pollen profiles can differ greatly from day-to-day, it is common practice to establish the time of day when peak concentrations are most likely to occur using seasonally averaged diurnal profiles. Atmospheric pollen loads are highly dependent upon emissions, and different species of grass are known to flower and emit pollen at different times of the day and during different periods of the pollen season. Pollen concentrations are also influenced by meteorological factors -directly through those parameters that govern pollen dispersion and transport, and indirectly through the weather-driven flowering process. We found that three different profiles dominated the grass pollen season in Aarhus -a twin peak profile during the early season, a single evening profile during the middle of the season, and a single midday peak during the late season. Whilst this variation could not be explained by meteorological factors, no inconsistencies were found with the theory that it was driven by a succession of different grass species with different diurnal flowering patterns dominating atmospheric pollen loads as the season progressed. The potential for exposure was found to be significantly greater during the late-season period than during either the early-or mid-season periods.

“…One of these -widely used in the past and still found today -is the period over which a given percentage of the total annual pollen count is recorded in the atmosphere (Nilsson and Persson, 1981;Andersen 1991;Torben, 1991;Gala´n et al, 1995). Another definition refers to the period between the first and last day with pollen counts higher or lower than a specific level (Davies and Smith, 1973;Giorato et al, 2000;Clot, 2001;Sa´nchez-Mesa et al, 2003).…”

May the definition of pollen season influence aerobiological results?

This paper reviews the terms and major criteria used to define and limit the pollen season. Pollen data from Cordoba (Spain), Ourense (Spain) and Bologna (Italy) were used to ascertain the extent to which aerobiological results and pollen curves are modified by the criteria selected. Results were analysed using SpearmanÕs correlation test. Phenological observations were also used to determine synchronization between pollen curves and plant phenology. The criteria for limiting the shortest and longest pollen season periods, as well as the earliest and latest start and end dates, varied according to the city and the taxon under study; in many cases, results for a given taxon also depended on the year. The smallest differences were obtained for Platanus and the greatest for Poaceae.

“…Thus, several authors have proposed methods to define the pollen season duration or phases such as the start, peak and end date (Nilsson and Persson, 1981;Lejoly-Gabriel and Leuschner, 1983;Andersen, 1991;Spieksma et al, 1995;Jager et al, 1996;Feher and Jarai-Komlodi, 1997;Giorato et al, 2000;Sanchez-Mesa et al, 2003). However, the accuracy of these methods is strongly connected to the taxon, the location and the large-scale weather conditions (Estrella et al, 2006;Jato et al, 2006).…”

Comparison of phenological, aerobiological and melissopalynological patterns of Olea europaea

-In the last few years, many studies have used airborne pollen to record the flowering season of plants. However, the airborne pollen found in traps does not always originate from or reflect the flowering period of the taxa from the studied surroundings. This study compared aerobiological, melissopalynological and flowering phenological data obtained from olive trees. The results of the study suggest that pollen loads collected by honeybees can be used as an alternative method to airborne pollen to record the flowering phenological phases and to provide accurate results.aerobiology / melissopalynology / phenology / pollen season / pollen loads / Apis mellifera
