“…The results of this study showed that data generated by both the gravimetric and volumetric methods nearly 30 years apart (and reported as relative frequency of occurrence) are similar, and consistent with the findings in other studies that report that the methods are comparable (Bhat & Rajasab, 1989; Charpin et al, 1991; Kasprzyk, 1996; Belmonte et al, 2000; Bricchi et al, 2000; Piotrowska & Weryszko-Chmielewska, 2003; and Teranishi et al, 2006). Latorre et al (2008) compared the Burkard, Rotorod, and Tauber samplers, and found that the Burkard trap provided more sensitive detection of pollen present at low concentrations when compared to the other two samplers.…”

“…For example, at low wind speeds, larger grains are more likely to fall than smaller ones; for normal wind speeds, however, the capture efficiency of particles between 26 and 43 lm seems to be equal (Gregory 1973). On the other hand, Bhat and Rajasab (1989) found that volumetric and gravimetric traps are equally efficient for determination of the qualitative and relative contribution of the individual components of the total aeroflora.…”

The atmosphere of Mar del Plata city (Argentina) was monitored using three different pollen traps-Burkard, Rotorod, and Tauber-during a flowering season (mid-winter to springtime) in order to compare the diversity and amounts of pollen grains collected in each trap. Sixty three percent of taxa diversity was simultaneously recorded by all three apparatuses. The five most abundant types of pollen in the three traps were Platanus, Ulmus, Quercus, Poaceae, and Fraxinus. The Tauber trap contained the most pollen from taxa with the largest grains, and exclusively trapped ten pollen types with entomophilous characteristics. The amount of pollen in each trap and local/extra-local plant abundance were compared to elucidate the effect of the method used on the pollen-vegetation relationship. The correlation coefficients for total pollen were positive and significant between all pairs of traps. The maximum peak was observed first in the Burkard trap, in agreement with an increase in temperature, but the general pattern in the three traps was similar, with a maximum in early spring. Opposite deviations from the mean value were observed for the Burkard and Tauber data; these deviations were associated negatively with wind speed and relative humidity, respectively. This paper discusses whether in some cases the pollen records could be used in an equivalent manner, although with some limitations.

“…However, the sampling methods have different sampling efficiencies. Thus, various researchers have been working on the relationship between sampling efficiency and sampling methods (e.g., Bhat & Rajasab, 1989;Crisp et al, 2013;Fiorina et al, 1997;Heffer et al, 2005;Jetschni & Jochner-Oette, 2021;Miki et al, 2017Miki et al, , 2019Toma ´s et al, 1997).…”

Evaluating inaccurate pollen concentrations caused by turbulence using passive sampler

Understanding the atmospheric concentration of pollen (which is one of the most common vectors of allergens) is necessary to determine the atmospheric allergen level. Airborne pollen concentrations were predominantly evaluated using volumetric and gravitational particle samplers. However, no previous studies have successfully shown whether these sampling methods can be used to evaluate actual airborne pollen concentrations. In this study, the relationship between wind speed and sampling efficiency was investigated to determine whether the influence of ambient wind speed on sampling efficiency was significant. To this end, the influence of wind speed was analyzed by comparing a volumetric sampler and a gravitational sampler. The experimental results indicate that an increase in the wind speed results in an increase in the sampling efficiency of the gravitational sampler because of fluctuations in the turbulence. Our simulation shows that when pollen is entrained in the turbulence, the changes in the wind speed, turbulence amplitude, and turbulence length influence the deposition rate of pollen on the gravitational sampler. These influences can be explained by the turbulence vibration model. These results show the inadequacy of existing evaluation methods, not only for pollen deposition data, but also for all types of bioaerosol deposition data.
