“…Researchers are therefore engaged in the development of innovative air monitoring technologies able to sample PM down the sub-micrometer scale, but also to collect sufficient quantities to allow the physicochemical characterisation of the particles (Liu et al 2023). However, even if advanced monitoring devices are being developed, currently their high costs do not permit to implement a satisfactory and up-todate spatial and temporal analysis of airborne PM (Gozzi et al 2016;Lucci et al 2023;Liu et al 2023).…”

“…Charge accumulation has been implicated in pollination: in bees, the friction surface is significantly increased by the presence of bristles and the accumulation of positive charges enhances pollen collection from flowers which are negatively charged (Vaknin et al 2000). Bees and other pollinators also use the electric fields generated between their body and the flowers to choose nectariferous and pollen-bearing sources: already visited flowers seem less attractive because their electric charge is weakened (Vaknin et al 2000;Khan et al 2021;Liu et al 2023).…”

The honey bee Apis mellifera has long been recognized as an ideal bioindicator for environmental pollution. These insects are exposed to pollutants during their foraging activities, making them effective samplers of environmental contaminants, including heavy metals, pesticides, radionuclides, and volatile organic compounds. Recently, it has been demonstrated that honey bees can be a valuable tool for monitoring and studying airborne PM pollution, a complex mixture of particles suspended in the air, known to have detrimental effects on human health. Airborne particles attached to the bees can be characterised for their morphology, size, and chemical composition using a scanning electron microscopy coupled with X-ray spectroscopy, thus providing key information on the emission sources of the particles, their environmental fate, and the potential to elicit inflammatory injury, oxidative damage, and other health effects in living organisms. Here, we present a comprehensive summary of the studies involving the use of honey bees to monitor airborne PM, including the limits of this approach and possible perspectives. The use of honey bees as a model organism for ecotoxicological studies involving pollutant PM is also presented and discussed, further highlighting the role of the bees as a cornerstone of human, animal, and environmental health, according to the principles of the “One Health” approach.

“…The previous study proved that the simultaneous particle precharging and filter polarizing achieved 99% one-pass efficiency for 0.3–0.5 μm particles with 21 Pa air resistance at 1 m/s filtering velocity . Although several studies have optimized the device structure , and the filter materials , to enhance particle capture efficiency, the performance and mechanism for bioaerosol inactivation have not been examined and understood.…”

Maintaining indoor air quality is essential for human health, and the threat posed by bioaerosols emphasizes efficient capture and inactivation technologies in ventilation systems. However, existing technologies struggle to capture and inactivate bioaerosols simultaneously with low air resistance and integrated technologies make them inconvenient in practical applications. To address this challenge, we developed a dual-zone electrostatically actuated filter in which airborne bacteria are first charged by ions generated in the charging zone and then captured by the polarized fibers and inactivated in the electrostatic field of the polarizing zone. Benefiting from the enhanced electrostatic force, the capture efficiencies for Escherichia coli (Gram-negative) and Staphylococcus epidermidis (Gram-positive) aerosols of 0.3−0.5 μm diameter increased from ∼25.4 to ∼98.4% at 0.5 m/s filtering velocity while the air resistance was maintained at only 4.5 Pa. The capture efficiency remained steadily high for 30 days, with an average of 93.8%. Moreover, the combination of the continued ion flow and electrostatic field exposure significantly improved the inactivation efficiency against E. coli and S. epidermidis to ∼98.7 and ∼96.1%, respectively, instead of allowing bacterial reproduction on the coarse filter without electrostatic actuation. The proposed dual-zone electrostatically actuated filter exhibits great potential for incorporation into energy-saving ventilation systems, offering highefficiency capture and antimicrobial performance as well as low air resistance.
