Background and Aim:
Iceland’s unique bio-geographical position between Europe and North America, combined with its Arctic and Boreal climates, results in distinctive environmental conditions that affect airborne pollen concentrations. Grass (Poaceae) pollen, a major allergen in Iceland, is monitored in two primary locations: Reykjavik (SW Iceland) and Akureyri (N Iceland). Pollen seasons in...
The spatiotemporal distribution of airborne pollen grains and fungal spores in Southeast Asia remains poorly understood. This study aims to address this gap by investigating potentially allergenic plants in the region, characterizing their pollen seasons, and assessing their clinical relevance. Through an extensive systematic literature review—conducted by screening the Scopus and PubMed...
Pollen allergy is one of the most common allergic diseases globally, affecting the quality of life of a significant portion of the population [1]. In Ukraine, there are three main pollination waves: the first, spring wave – pollination of woody plants (with Betula – birch having the most allergenic pollen), the second – summer wave caused by grass pollen, and the third, autumn wave – caused by...
BACKGROUND
Fungal spores constitute a significant fraction of visible atmospheric bioaerosols. While they play an essential role in decomposing organic matter within ecosystems, they can also negatively impact on agricultural crops and human health. Despite their immense diversity and abundance, fungal spores remain relatively understudied. Although some research has explored the full...
Background: Environmental allergens represent a large group of important triggers for seasonal and perennial allergies. Among these, outdoor allergens, comprising both plant pollen and fungal spores, form a distinct category of seasonal allergy triggers that are difficult to avoid during their pollination or sporulation periods. Consequently, patients may be exposed to these allergens for...
Aim of the study:
Although its main purpose is to ensure sexual reproduction, birch pollen grain is also responsible for allergenic rhinitis and asthma, also known as pollinosis. In Northern Europe, Betula pendula is the birch species with the most allergenic pollen (P. Beck et al. 2016; G. D’Amato et al. 2007; Emberlin et al. 2002). Alteration of pollen fertility, changes of protein and...
Background: While pollen calendars are common, spore calendars are rare due to the limited number of aerobiological stations worldwide that monitor fungal spores. However, many fungi are known to cause allergic reactions and are important to consider when estimating seasonal allergy risk factors globally. The aim of our study was to identify the most numerous fungi and their sporulation...
Background
Climate change significantly affects plant life cycles, including flowering, particularly in anemophilous species, which can release high concentrations of allergenic pollen into the air. Changes in meteorological variables and air pollution can lead to earlier onset, prolonged duration, and increased intensity of pollen seasons, with adverse effects on individuals suffering...
Modern technologies in representation of the future atmospheric conditions are relying on the use of three-dimensional numerical models. The advancements in the weather prediction and air quality models had provided a physically grounded prerequisites (served a solid basis) for the development of numerical pollen forecasts. In many numerical models, the pollen grains are considered as the...
