The Spanish Aerobiology Network (REA) was funded in 1992 (http://www.uco.es/rea/). This is an academic-research network, comprising teaching and/or research staff specialising in different scientific areas, i.e., Botany, Mycology, Palynology and Atmospheric Dynamics. This is a Technical Network within the Spanish Aerobiology Association (AEA) since the Association was formed in 1995...
Fungal spores are considered some of the most important aeroallergens, triggering allergenic symptoms and further exacerbating existing respiratory conditions. Predicting periods when ambient concentrations of allergenic fungal spores will be high, represents an important resource for allergy sufferers and those suffering from respiratory conditions such as asthma. Aerobiological surveys have...
Olive trees usually have an alternate bearing in their fruit production. This phenomenon consists of alternating high and low fruit productivity between consecutive years and, usually, it is caused by the high demand for nutrients that the plants require to fructify. This biannual cycle constitutes a major economic problem for olive growers and, consequently, a lot of interest is put in...
Intermittent allergic rhinitis has very obvious seasonality, which is caused by the periodical nature of the vegetative season of plants and fungi. It is also known that despite a drastic decrease in the pollen concentrations in autumn, symptoms of allergy and asthma persist during the autumn period too. It can be explained by the relatively high concentrations of fungal spores, which are...
The pollen grains of invasive Ambrosia species contain very potent allergens and can be transported vast distances when conditions are favourable. In this study we present the first airborne Ambrosia pollen measurements recorded by an automatic sampler with 1-hour and sub-hourly resolution (i.e. 1-minute and 1-second data).
The data were collected by traditional Hirst-type methods and a...
Air plays an important role in the health of the population (World Health Organization, 2021). Airborne bioaerosols such as pollen grains cause pulmonary and cardiovascular diseases in allergic citizens, around 30% of the world's population (Brunekreef et al., 2000). Among the most allergenic pollen grains are those of the families of Poaceae, Oleacea, Urticaceae, Compositae, and...
Grass pollen is one of the major causes of allergy, affecting 10-30% of the population around the globe. About 100 species of grass could be found in the European part of Russia, but the time of flowering and the allergenicity of different grass species are not the same.
The primary source of information on grasses' pollen content in the air is classical aerobiological monitoring, but...
Pollen of allergenic species is an important issue in the healthcare system in Ukraine. It is especially important in cities and suburbs as potential sources of allergenic pollen. What is more, allergenic tree species were planted in the urbanized territories before and their planting continues, despite the potential ability of their pollen to cause allergies. Thus, at the moment, large...
Nowadays, there is an increasing emphasis on the problem of invasive species. In areas where the tree of heaven (Ailanthus altissima) appears and multiplies, the original vegetation degrades and transforms. The tree of heaven is of great importance in urban environments, where it causes building damage, static problems, and endangers utilities. In addition, it is worth mentioning that the...
Bioaerosols are omnipresent within all ecosystems globally and have been shown to have serious impacts on human, animal, and plant health, with additional climatic affects noted. Thus, an understanding of the seasonal variation of bioaerosols such as pollen and fungal spores and the associated species with these categories is of great interest to the public, policy makers and academics alike....
One of the most common allergens in Ukraine is ragweed pollen. It intervened here from the American continent a hundred years ago. The most ragweed-contaminated regions are Kherson, Odessa, Mykolaiv, Zaporizhia, Donetsk, Dnipropetrovsk, and Kirovohrad regions. According to our preliminary data, approximately 40% of people with hay fever are susceptible to ragweed. And it is believed that this...
