“…This study showed a clear relationship between meteorological variables and pollen or allergen concentration. This is, however, in contrast with the results obtained by other researchers ( De Linares et al., 2010 ; Plaza et al., 2016 ), who noted no correlation between aeroallergen concentration and weather parameters. The present study found precipitation to be a significant factor explaining the variability in grass pollen and Phl p 5 allergen concentrations during the MPS period, confirming the ability of rain to remove pollen grains from the atmosphere.…”

“…Air temperature is considered as a meteorological factor responsible for anther opening, pollen release and atmospheric pollen dispersal ( Fernández-González et al., 2011 ). Even though the significant positive correlation between airborne Poaceae pollen and the air temperature was observed by other researchers ( Bartková-Ščevková, 2003 ; Plaza et al., 2016 ), no significant association between air temperature and pollen levels was observed in the present study. On the other hand, D'Amato et al.…”

“…The quantity of pollen grains in the atmosphere depends on many factors that affect their release from anthers and airborne dispersal. Apart from the biological characteristics of the source plants and aerodynamic features of pollen grains, meteorological factors belong to the most significant variables that affect the variation in airborne pollen concentration ( Plaza et al., 2016 ). In general higher Poaceae pollen concentrations are associated with bright sunny days without precipitation ( Bartková-Ščevková, 2003 ).…”

The sensitization to grass pollen is a known problem in European countries. Phl p 5 is an important allergen recognized by the majority of grass sensitized individuals. In this study, we evaluated daily variation in airborne Poaceae pollen and Phl p 5 allergen concentrations to determine whether airborne pollen concentrations alone are sufficient to reflect the actual allergenic potential of the air. The relationships between the mentioned pollen and allergen concentrations and associated environmental variables were also examined. The airborne particles were collected during the Poaceae flowering season in Bratislava in 2019. Pollen sampling was performed using a Hirst-type sampler, while a cyclone sampler was used for the aeroallergen capturing. Allergenic molecules were quantified by ELISA assay. The associations between pollen and allergen concentrations showed that these two variables are positively correlated; however, the correlation was not significant. We observed the concurrent occurrence of airborne pollen and allergen peaks on the same day. Nevertheless, during some days of the pollen season, the allergen concentrations did not correspond to the airborne pollen values. Moreover, the days with low pollen concentration but high pollen potency and vice versa were observed. The effect of selected environmental variables on daily pollen and allergen concentrations was evaluated through Spearman ' s correlation analysis. Of all meteorological variables considered, air temperature, precipitation, and relative air humidity were significantly correlated with airborne pollen and/or allergen concentrations. The association with air temperature was positive, while the negative association was observed with precipitation and relative air humidity. Among the atmospheric pollutants, O 3 and PM 10 were significantly and positively associated with both pollen and allergen concentrations, whereas CO and PM 2.5 were significantly and positively associated only with pollen concentration.

“…The pollen of grass species pollinated by wind can represent a significant health risk because of its high allergenic potential [13]. These grass species are considered the main cause to pollen allergies in many parts of the world [14][15][16]. Airborne pollen concentrations have traditionally been used to establish potential exposure to airborne allergens.…”

“…Nevertheless, research has shown that allergy symptoms may arise even at low pollen concentrations [17]. Moreover, there are not only allergens linked to pollen grains and non-pollen-bound allergenic substances but also free allergens that can be also found in the atmosphere [14,18]. Recently, the role of grass pollen in respiratory allergy was confirmed in the European Community Respiratory Health Study [17,19].…”

When the landfill use comes to end, important subsequent steps include aftercare, safety assurance, and ecological regeneration. Landfill revegetation is cost-effective and eco-friendly approach in the management of landfill areas, which serves the purpose of stabilization and provides a pleasant landscape. There are various vegetation types that can be planted, yet grass species are often used for low-cost reasons. Plants can be important sources of air pollution, particularly by grass pollen. The main goal of our study was to identify plant species that produce allergenic pollen. Long-term vegetation monitoring took place on three sites in the growing seasons of years 2008–2018. Studied objects were landfills located in the Czech Republic. The vegetation was assessed using a floristic survey of identified plant species. Plant species that produced allergens were recorded. During the monitoring, 298 plant species were determined. Plant species with allergenic pollen have a considerable share in the landfill vegetation. Thus, landfills are potential sources of various kinds of allergenic pollen. Moreover, our results indicated that there are three periods of pollen production: early spring, late spring, and early summer; late summer; and autumn. The second period is typical for the production of highly allergenic pollen by grasses. Most detected plant species with allergenic pollen are common for all monitored sites, which demonstrates that the vegetation of landfills is a significant source of allergenic pollen.

This study focused on phenological timing and spatial patterns in 30 Poaceae species flowering in spring in different types of plant cover (scrub, riverbank and pasture). Grass community composition was studied, and the influence of species and plant cover on the start date and duration of flowering was assessed from March to June in both 2014 and 2015. Twenty-nine sampling sites were selected for phenological monitoring using the BBCH scale. Data were subjected to GLMM analyses. Binary discriminant analysis revealed differences in grass community composition as a function of plant cover type; scrub cover comprised a considerably larger number of species than those in riverbank and pasture. Moreover, more species diversity was observed in 2014 than in 2015 with a drier and stressed pre-flowering period. Differences on phenology were also recorded between plant cover types and study years. Species in pasture and riverbank flowered before (113.4 days; 116.1 days) than species in scrub (120.9 days), being these species with shorter flowering length because they are more exposed to the characteristic of the Mediterranean region during the summer. In general, flowering onset occurred later in 2014 (118.2 days) than in 2015 (115.8 days), probably attributable to precipitation occurring during March. On the other hand, spatial autocorrelation within some cover types has been observed, showing spatial patterns exist at a smaller scale. The findings of this study contribute to a better understanding of grass phenology in different environments.
