Fungal spores often cause allergic diseases in people working outdoors, especially in agriculture. In the case of vineyard workers, the threat of mycotoxins is generally considered, and aerobiological monitoring focuses mainly on pathogenic fungi that cause diseases in grapes. The current requirement is to increase knowledge regarding the risk to vineyard workers coming from highly allergenic fungal spores such as Alternaria and Epicoccum. Aerobiological monitoring was conducted using the volumetric method. The relationships between meteorological parameters and airborne fungal concentrations were detected using Spearman's correlation and a logistic regression model. It was found that this risk is significant and is particularly strong from July to September, when periods of high concentrations of Alternaria and Epicoccum spores overlap. High concentrations of spores are favoured by an increase in air temperature, sunshine duration, and low relative humidity. When the weather conditions are favourable for the release and dispersion of spores, their concentration exceeds the threshold to trigger allergic reactions in sufferers. Due to their high concentrations and cross-reactions of their allergens with other aeroallergens, airborne fungal spores may pose a health risk to allergy sufferers working in vineyards. For this reason, aerobiological monitoring is particularly important in agricultural workplace. [ABSTRACT FROM AUTHOR]

The dataset presents a 43 year-long reanalysis of pollen seasons for three major allergenic genera of trees in Europe: alder (Alnus), birch (Betula), and olive (Olea). Driven by the meteorological reanalysis ERA5, the atmospheric composition model SILAM predicted the flowering period and calculated the Europe-wide dispersion pattern of pollen for the years 1980-2022. The model applied an extended 4-dimensional variational data assimilation of in-situ observations of aerobiological networks in 34 European countries to reproduce the inter-annual variability and trends of pollen production and distribution. The control variable of the assimilation procedure was the total pollen release during each flowering season, implemented as an annual correction factor to the mean pollen production. The dataset was designed as an input to studies on climate-induced and anthropogenically driven changes in the European vegetation, biodiversity monitoring, bioaerosol modelling and assessment, as well as, in combination with intra-seasonal observations, for health-related applications., (© 2024.
