Special Issue Information

Dear Colleagues,

Exposure to high amounts of atmospheric aerosol particles, including their biological components like bacteria, fungal spores, pollen, molds, and viruses, is related to significant deteriorations of the ecosystem and public health. In fact, the distribution of aerosols and bioaerosols is ubiquitous in the environment, with the atmosphere representing one of the most relevant means of their dispersal. In addition, aerosols possess a relatively long residence time in the atmosphere because of their small-scale size and, consequently, they can be transported over extended distances. Therefore, the possible effects of the aerosol particles on different fields like human health, cultivation, food production, ecosystem's condition, biogeochemical cycles, and atmospheric processes make their properties of great interest to the scientific community.

This Special Issue will explore the current knowledge about interactions among the optical and microphysical properties of aerosol particles and their biological components. In addition, this Special Issue aims to investigate the influence of meteorology, seasonal changes, and the advection of long-range-transported air masses on the detection of possible reasons for the atmospheric aerosol composition. We will consider both experimental and model-based works characterizing aerosols and bioaerosols in different types of environments. Authors are also encouraged to submit manuscripts based on particulate matter detection and monitoring devices and/or on advanced approaches.

This study aims to investigate the seasonal variation and source identification of fluorescent aerosol particles at the monitoring site of the University of Salento in Lecce, southeastern Italy. Utilizing a wideband integrated bioaerosol sensor (WIBS), this research work analyzes data from two specific monitoring days: one in winter (10 January 2024), marked by significant transport of anthropogenic particles from Eastern Europe, and another in early spring (6 March 2024), characterized by marine aerosol sources and occasional desert dust. This study focuses on the seven WIBS particle categories (A, B, C, AB, AC, BC, ABC), which exhibited distinct characteristics between the two days, indicating different aerosol compositions. Winter measurements revealed a predominance of fine-mode particles, particularly soot and bacteria. In contrast, spring measurements showed larger particles, including fungal spores, pollen fragments, and mineral dust. Fluorescence intensity data further emphasized an increase in biological and organic airborne material in early spring. These results highlight the dynamic nature of fluorescent aerosol sources in the Mediterranean region and the necessity of continuous monitoring for air quality assessments. By integrating WIBS measurements with air mass back-trajectories, this study effectively identifies fluorescent aerosol sources and their seasonal impacts, offering valuable insights into the environmental and health implications of aerosol variability in the investigated Mediterranean area.
