Lags between meteorological variables and Alternaria concentration of 1, 2, and 3 days were examined.…”

Alternaria spores are found in the atmosphere in many locations around the world. They are significant from a human health perspective because they have been known to trigger allergic respiratory disease such as asthma and hay-fever. The presence of Alternaria spores in the atmosphere has been related to meteorological factors in past studies, but this has not been done previously in Sydney, Australia. This paper reports the results of such a study in Sydney. Alternaria spore concentration data for the period 19 August 1992 to 31 December 1995 were examined with meteorological data for the same period. The daily Alternaria spore concentration was compared to the meteorological data for the same day and for up to 3 days previously. The analysis methods were Spearman's rank correlation and multiple regression. Alternaria spores appear in the atmosphere of Sydney year-round, although they peak over spring, summer, and autumn. A number of meteorological factors, including mean, minimum, and maximum, temperature, dew point temperature, and air pressure, are significantly correlated with the atmospheric concentration of Alternaria spores. Some of these meteorological variables (temperature and dew point temperature) show significant correlations with a 1, 2, and 3 day lag, as well as for the same day. Regression models indicate that up to 31.1% of the variation in Alternaria spore concentration can be explained by meteorological factors. There is potential for the results of this study to be used by public health authorities in the prediction of Alternaria spore concentrations in Sydney.

“…Vegetation of the trapping site and the surroundings includes open and riparian Eucalyptus woodland with an understorey of Poaceae and herbaceous species. Grasses represented include Capillipedium spp., Chloris gayana, Cynodon dactylon, Eleusine tristachya, Lolium temulentum, Sorghum halepense, Avena fatua, Dactylis glomerata and Paspalum notatum (Moss 1965;Rutherford et al 1997;Green et al 2002). The nearby urban and industrial areas include grassed and wooded areas of both endemic and exotic species.…”

Grass pollen is an important risk factor for allergic rhinitis and asthma in Australia and is the most prevalent pollen component of the aerospora of Brisbane, accounting for 71.6% of the annual airborne pollen load. A 5-year (June 1994-May 1999) monitoring program shows the grass pollen season to occur during the summer and autumn months (December-April), however the timing of onset and intensity of the season vary from year to year. During the pollen season, Poaceae counts exceeding 30 grains m(-3) were recorded on 244 days and coincided with maximum temperatures of 28.1 +/- 2.0 degrees C. In this study, statistical associations between atmospheric grass pollen loads and several weather parameters, including maximum temperature, minimum temperature and precipitation, were investigated. Spearman's correlation analysis demonstrated that daily grass pollen counts were positively associated (P < 0.0001) with maximum and minimum temperature during each sampling year. Precipitation, although considered a less important daily factor (P < 0.05), was observed to remove pollen grains from the atmosphere during significant periods of rainfall. This study provides the first insight into the influence of meteorological variables, in particular temperature, on atmospheric Poaceae pollen counts in Brisbane. An awareness of these associations is critical for the prevention and management of allergy and asthma for atopic individuals within this region.

“…In the southern hemisphere, patterns appear to differ: In La Plata, Cladosporium peaks are recorded in February (Mallo et al, 2011), whilst in Santiago de Chile and also in Australia, peak concentrations are logged in April and May (Rutherford et al, 1997;Ibáñez et al, 2001). At many of the stations in the present study, peak spore concentrations were recorded in summer; similar results have been reported by other authors for Salamanca (Perez-Gorjón et al, 2003).…”
