Ornamental trees can reduce some of the negative impacts of urbanization on citizens but some species, such as Platanus spp., produce pollen with high allergenic potential. This can exacerbate the symptomatology in allergic patients, being a public health problem. Therefore, it would be relevant to determine the environmental conditions regulating...
Airborne pollen is produced by plants for their sexual reproduction and can have negative impacts on public health. The current monitoring systems are based on manual sampling processes which are tedious and time-consuming. Due to that, pollen concentrations are often reported with a delay of up to one week. In this study, we present an open-source...
Sierra de las Nieves (southern Spain) was declared National Park in 2021. Around 100 000 people visit the park every year and a high percentage of them may suffer allergy symptoms due to presence of some pollen types in the atmosphere. Therefore, it is of great interest to determine the seasonality and intensity of the airborne pollen concentration...
Airborne pollen concentrations are influenced by wind direction, wind speed, temperature and rainfall among other meteorological variables, but they are conditioned by local land use. Combining land use and wind frequencies within a single variable would allow the estimation of the contribution of the emission sources to the airborne pollen detecte...
Due to the increase in allergies, aerobio-logical studies carried out in cities are essential to keep the population informed about the pollen atmospheric concentrations detected. However, the high cost and complexity of aerobiological studies often mean that the information is generated from a single sampling point that may not be representative o...

Pollen calendars are graphical representations that summarize the general annual dynamics of the more abundant airborne pollen types detected in the atmosphere of a certain location. To elaborate them, it is recommended to have continuous pollen sampling data from a period of, at least, 5 years in order to such pollen calendar be representative. Ho...
Alternaria conidia have high allergenic potential and they can trigger important respiratory diseases. Due to that and to their extensive detection period, airborne Alternaria spores are considered as a relevant airborne allergenic particle. Several studies have been developed in order to predict the human exposure to this aeroallergen and to preve...
Missing data is a common problem in scientific research. The availability of extensive environmental time series is usually laborious and difficult, and sometimes unexpected failures are not detected until samples are processed. Consequently, environmental databases frequently have some gaps with missing data in it. Applying an interpolation method...
Significance
Coexposure to airborne pollen enhances susceptibility to respiratory viral infections, regardless of the allergy status. We hypothesized this could be also true for SARS-CoV-2 infections. To investigate this, we tested for relationships between SARS-CoV-2 infection rates and pollen concentrations, along with humidity, temperature, popu...
Alnus pollen has been frequently detected in the atmosphere of different airborne sampling sites of Southern Spain. However, Alnus sp. populations are very scarce and fragmented in the area, being restricted to a few river valleys in the southwest, and other further away regions of the Iberian Peninsula. This leads to think that the airborne pollen...
