Special Issue Information

Dear Colleagues,

Biological aerosol, known as bioaerosol, is poorly constrained but has direct and indirect impacts on air quality, climate, and human health. Detecting and characterizing outdoor and indoor bioaerosol is critical as such knowledge is an essential prerequisite for policy interventions. Bioaerosols normally comprise viruses, bacteria, fungi, and pollen. Historically, offline techniques have been utilized to detect different types of bioaerosols and characterize their physical and chemical properties, as well as their environmental toxicity. Knowledge from integrated filter samples sometimes hinders our deep understanding of the release mechanisms of bioaerosols, which is the key for bioaerosol forecasting. With recent advances in fluorescence spectrometers, the detection, discrimination, and forecasting of different bioaerosols in real-time become possible.

In this Special Issue of Atmosphere, entitled “Real-Time Detection, Discrimination, and Forecasting of Bioaerosols”, we call for novel papers addressing the detection, discrimination, and forecasting of bioaerosols in real-time. The aim is to introduce recent advances in bioaerosol-related measurement science and data science. These studies include, but are not limited to, field measurement reports, exploring environmental drivers of release mechanisms of bioaerosols, health impacts and interventions of bioaerosols, and data analytics in bioaerosol science.

Casuarina (Australian pine, She-oak) is native to Australia and South East Asia and is known for its abundant wind-borne pollen. Despite not being considered a major aeroallergen, some patients report respiratory symptoms upon exposure, with positive skin prick tests (SPT) to Casuarina pollen extract. This study investigates Casuarina pollen dispersal patterns in Sydney, Australia, over a 10-year period, from 2008 to 2018, revealing a bimodal distribution of pollen from September to October (southern hemisphere spring) and February to March (mid-late summer). Analysis of historical SPT data shows 20% of individuals with respiratory allergies reacting positively to Casuarina pollen extract, with almost 90% of these also reacting to grass pollen, suggesting potential cross-reactivity. Notably, there are no exclusive reactions to Casuarina pollen. Understanding the prolonged pollen season underscores the importance of year-round monitoring for accurate characterization. Currently lacking are commercially available skin test extracts or specific IgE assays for Casuarina sensitization, necessitating challenge studies to confirm clinical symptoms directly attributable to Casuarina pollen. By elucidating the seasonal dynamics and meteorological drivers of Casuarina pollen dispersion, alongside the potential allergenicity suggested by skin prick tests, this study paves the way for improved management of Casuarina-related allergies and highlights the critical need for further research on native Australian plant allergens.
