“…Spatial dependence as a function of land use of the honey, bee tissue, and bee pollen TE results agrees with previous studies elsewhere in the world, for example, the United States, Serbia, and Australia (Bromenshenk et al, 1985;Zarić et al, 2018b;Zhou, Taylor, Davies, & Prasad, 2018) and locally (Smith et al, 2019). An early study in the Seattle-Tacoma area (Washington, USA) showed increased amounts of As and Cd in bees near the Port of Tacoma (Bromenshenk et al, 1985).…”

“…An early study in the Seattle-Tacoma area (Washington, USA) showed increased amounts of As and Cd in bees near the Port of Tacoma (Bromenshenk et al, 1985). In the Serbian studies by Zarić et al (2016Zarić et al ( , 2018b, the authors measured higher concentrations of certain TEs in bee tissue within Belgrade (e.g., Sb, presumably from vehicle brake pads) and higher concentrations of Al, Cr, Fe, and Li (constituents of fly ash) in bees collected near thermal power plants, compared to bees from rural and non-industrialized areas. Locally, Pb, V, Sb, and Fe in honey, bees, and bee pollen exhibit geospatial trends in agreement with honey in the pilot study in Vancouver, BC (Smith et al, 2019): higher concentrations in areas of greater urban density and industrial activity relative to suburban and rural samples.…”

“…A very recent development in this field is the use of Pb isotopes to improve the pollution source apportionment capability of honey and bees, particularly in urban centers (Smith et al, 2019;Zarić et al, 2018b;Zhou, Taylor, Davies, & Prasad, 2018). The application of Pb isotopes is quite promising so far: Isotopic compositions for honey and bees are well-supported by other environmental monitoring materials or proxies, for example, topsoil and native bees in Sydney, Australia Zhou, Taylor, Davies, & Prasad, 2018) and sediments, shellfish, and salmon tissue near Vancouver, BC (Li et al, 2020;Shiel et al, 2012;Smith et al, 2019).…”

Assessing metal distributions in cities is an important aspect of urban environmental quality management. Western honeybees (Apis mellifera) and their products are biomonitors that can elucidate small-scale metal distribution within a city. We compare range and variations in trace element (TE) concentrations and lead (Pb) isotopic compositions of honey, bee tissue, bee pollen, and propolis collected throughout Metro Vancouver (BC, Canada). Honey, bee, and bee pollen results have similar TE and isotopic trends; samples collected in urban and industrialized areas exhibit elevated concentrations of anthropogenically influenced TE (e.g., Pb, Zn, V, and Ti) and a less radiogenic Pb isotopic composition (i.e., lower 206 Pb/ 207 Pb and elevated 208 Pb/ 206 Pb) relative to their suburban and rural counterparts. For example, 206 Pb/ 207 Pb, 208 Pb/ 206 Pb in honey range from 1.126, 2.131 and 1.184, 2.063; extremes measured in honey from urban and suburban/rural areas, respectively. Except for propolis, measured and interpolated (kriged) results in all materials reflect the immediate zoning or land use setting near the hive, providing kilometer-scale geospatial resolution, suitable for monitoring urban systems. Statistical analysis reveals that no systematic variations or intra-or inter-annual trends exist in TE concentrations or Pb isotopic compositions, including among sampling and field methods (i.e., old vs. new hive equipment and honey from the brood nest box vs. honey super). The results of this systematic study using honeybees and hive products in Metro Vancouver provide a robust, current baseline for future comparison of local land use and environmental policy change.

“…In social insects and especially honeybees, the collection of fine particulate matter during foraging translates into an accumulation of xenobiotics in honey and beebread. Comparisons between apiaries have often shown higher levels of residues of pesticides, heavy metals, and other particulate matter in the bees themselves or honey in urbanized or industrialized areas in comparison to rural areas [32,66,70,210,219,220].…”

Many insect species, including social insects, are currently declining in abundance and diversity. Pollutants such as pesticides, heavy metals, or airborne fine particulate matter from agricultural and industrial sources are among the factors driving this decline. While these pollutants can have direct detrimental effects, they can also result in negative interactive effects when social insects are simultaneously exposed to multiple stressors. For example, sublethal effects of pollutants can increase the disease susceptibility of social insects, and thereby jeopardize their survival. Here we review how pesticides, heavy metals, or airborne fine particulate matter interact with social insect physiology and especially the insects’ immune system. We then give an overview of the current knowledge of the interactive effects of these pollutants with pathogens or parasites. While the effects of pesticide exposure on social insects and their interactions with pathogens have been relatively well studied, the effects of other pollutants, such as heavy metals in soil or fine particulate matter from combustion, vehicular transport, agriculture, and coal mining are still largely unknown. We therefore provide an overview of urgently needed knowledge in order to mitigate the decline of social insects.

“…Honeybees foraging for explosives residues potentially have the advantage of being able to access terrain that may be difficult for humans or larger animals such as dogs, to safely survey. Honeybees have previously been used in biosensing applications for targets including radionuclides, pollutants, and explosives (Barisic D et al, 2002;Girotti et al, 2013;Rodacy et al, 2002;Zarić et al, 2018).…”

Trace sensing of explosive vapours is a method in humanitarian demining and Improvised Explosives Device (IED) detection that has received increasing attention recently, since accurate, fast, and reliable chemical detection is highly important for threat identification.However, trace molecule sampling in the field can be extremely difficult due to factors including weather, locale, and very low vapour pressure of the explosive. Preconcentration of target molecules onto a substrate can provide a method to collect higher amounts of analyte for analysis. We used the commercial fluoropolymer Aflas as a preconcentrator material to sorb explosive molecules to the surface, allowing subsequent detection of the explosives via the luminescence quenching response from the organic polymer Super ACCEPTED MANUSCRIPTHighlights  Trace detection of explosive vapours is challenging in real-world environments. By "preconcentrating" trace vapours onto solid substrates, higher amounts can be collected for detection. Our approach combines fluoropolymer preconcentrators, free-flying honeybees for sampling, and luminescent thin films as the sensing mechanism. The inexpensive, commercially-available fluoropolymer Aflas has shown good preconcentration abilities for 2,4-DNT which is typically found in landmines. Laboratory results and initial field results indicate this method is a very promising tool for the detection of trace explosive vapours in contaminated land.
