Bioaerosols, including pollen, spores, and bacteria, are essential atmospheric components that significantly influence climate, ecosystems, and human health. These particles participate in various ecological processes, contribute to environmental sustainability, and play a crucial role in cloud formation, thereby affecting climate regulation. Wind-dispersed bioaerosols support ecosystem stability and health while also impacting agricultural and forestry activities. Despite their considerable ecological significance, the effects of bioaerosols on human health are becoming an increasing concern. In recent decades, rising concentrations of airborne allergens have been linked to a growing prevalence of allergies and asthma across Europe. However, research in this field continues to face challenges. Traditional methods for studying bioaerosols often fail to meet contemporary scientific standards, and knowledge of their composition and effects remains fragmented.
This study aims to advance bioaerosol research by employing an innovative environmental DNA (eDNA) approach. This method enables the efficient identification and analysis of genetic material dispersed in the atmosphere, offering new opportunities for bioaerosol monitoring. The research seeks to: (i) assess the sensitivity and specificity of the eDNA method in studying bioaerosol particles, including allergenic ones; (ii) develop a methodology for integrating eDNA-derived data with findings from traditional bioaerosol monitoring techniques; (iii) analyse the influence of air pollution and meteorological factors on the transport and deposition of atmospheric DNA.
The anticipated findings will provide deeper insights into the characteristics of atmospheric DNA, yielding valuable knowledge for biodiversity conservation and public health. This research will enhance ecological monitoring techniques, improve the surveillance of airborne allergens and pathogens, and offer new perspectives on agricultural and forestry practices. These advancements will facilitate more effective biodiversity management, mitigate risks associated with allergies and respiratory diseases, and optimise plant protection strategies.
