The concept of ecosystem services is widely understood as the services and benefits thatecosystems provide to humans, and they have been categorised into provisioning, regulating, supporting, and cultural services. This article aims to provide an updated overview of the benefits that the honey bee Apis mellifera provides to humans as well as ecosystems. We revised the role of honey bees as pollinators in natural ecosystems to preserve and restore the local biodiversity of wild plants; in agro-ecosystems, this species is widely used to enhance crop yield and quality, meeting the increasing food demand. Beekeeping activity provides humans not only with high-quality food but also with substances used as raw materials and in pharmaceuticals, and in polluted areas, bees convey valuable information on the environmental presence of pollutants and their impact on human and ecosystem health. Finally, the role of the honey bee in symbolic tradition, mysticism, and the cultural values of the bee habitats are also presented. Overall, we suggest that the symbolic value of the honey bee is the most important role played by this insect species, as it may help revitalise and strengthen the intimate and reciprocal relationship between humans and the natural world, avoiding the inaccuracy of considering the ecosystems as mere providers of services to humans.

Throughout history, honey has been used for many different purposes and due to its medicinal properties, has been one of the products marketed by traders. The figure of the bee first appeared in drawings on rock with the history of humanity, then on statues, as a logo, on money or stamps, and also in movies. Beekeeping museums, which present the historical process of beekeeping, also reflect an important culture with their ancient hives, documents, beekeeping materials, and historical antiquities. The contribution of bees to the sustainability of natural life is very important and has a history of 100 million years. The importance of bees and their by-products is increasing day by day, and the demand for the beekeeping industry as alternative income determines the emergence of new products and activities. Based on its health properties, apitherapy is the basis of activities such as api-air and api-diet. In natural regions (i.e., mountainous areas, forests) where beekeeping is carried out, people’s tradition, food culture, and healthy lifestyle attract society’s attention. In this context, api-tourist activity appears as a new phenomenon. In this article, the existing literature was scanned to create a resource about these new fields triggered by the beekeeping sector.

Particulate matter (PM) is a complex mixture of airborne chemical compounds commonly classified by their aerodynamic diameter. Although PM toxicity strongly depends on the morphology, chemical composition, and dimensions of particles, exposure limits set by environmental organisations only refer to the mean mass concentration of PM sampled daily or annually by monitoring stations.

The global demand for bee pollen as a dietary supplement for human nutrition is increasing. Pollen, which comprises proteins and lipids from bees’ diets, is rich in essential amino acids, omega fatty acids, and bioactive compounds that can have beneficial effects on human health. However, bee pollen may also contain contaminants due to environmental contamination. To date, data on bee pollen contamination by environmental pollutants refer almost exclusively to pesticides and heavy metals, and very little information is available on the potential contamination of bee pollen by airborne particulate matter (PM), a ubiquitous pollutant that originates from a wide range of anthropogenic sources (e.g., motor vehicles, industrial processes, agricultural operations). In the present study, pollen grains collected by forager bees living in an industrial area of the Po Valley (Northern Italy) were analyzed for contamination by inorganic PM. The morpho-chemical characterization of inorganic particles using SEM/EDX allowed us to identify different emission sources and demonstrate the potential risk of PM entering the food chain and exposing bees to its ingestion.

Urban areas present multiple challenges to scientists interested in unraveling the source, transport, and fate of airborne particulate matter (PM). Airborne PM consists of a heterogeneous mixture of particles with different sizes, morphologies, and chemical compositions. However, standard air quality stations only detect the mass concentration of PM mixtures with aerodynamic diameters ≤10 μm (PM₁₀) and/or ≤ 2.5 μm (PM_2.5). During honey bee foraging flights, airborne PM up to 10 μm in size attaches to their bodies, making them suitable for collecting spatiotemporal data on airborne PM. The individual particulate chemistry of this PM can be assessed using scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy on a sub-micrometer scale, allowing accurate identification and classification of the particles. Herein, we analyzed the PM fractions of 10-2.5 μm, 2.5-1 μm, and below 1 μm in average geometric diameter collected by bees from hives located in the city of Milan, Italy. Bees showed contamination by natural dust, originating from soil erosion and rock outcropping in the foraging area, and particles with recurrent heavy metal content, most likely attributed to vehicular braking systems and possibly tires (non-exhaust PM). Notably, approximately 80% of non-exhaust PM was ≤1 μm in size. This study provides a possible alternative strategy to apportion the finer fraction of PM in urban areas and determine citizens' exposure. Our findings may also prompt decision-makers to issue policy addressal for non-exhaust pollution, especially for the ongoing restructuring of European regulations on mobility and the shift toward electric vehicles whose contribution to PM pollution is debated.
