“…For this reason it is important to know what are the types and contents of these mixed pollens, which are sold in the markets and people use as food supplement. As mentioned by Kasiotis et al (2014), Oliveira et al (2016), Roszko et al (2016), bee products and pollens are potential bioindicators of the presence of contaminants in the environment since bees travel long distances. In our study we determined six types of pollen belonging to four families and the pollen morphology results matched those described by Sorkun (2008) and Paldat (2016).…”

Bee pollen, an important bee product, is harvested as a food supplement for humans, so it must be safe in terms of toxic components for consumption. The aim of this study is to determine the amounts of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), dioxin-like polychlorinated biphenyls (dl-PCBs) and non dioxin-like PCBs (ndl-PCBs) in the bee pollen pellets of Apis mellifera L. collected from Çankırı, located in the central Anatolia region of Turkey, between June and July 2014. Six types of pollen belonging to four families: Centaurea triumfettii L. - Asteraceae family; Brassica spp. L. - Brassicaceae family; Cistus spp. L. - Cistaceae family; Onobrychis spp. L., Hedysarum spp. L. and Trifolium spp. L. - Fabaceae family, were determined through microscopic analysis. Dioxin and PCB congeners were determined in a pooled bee pollen sample and all the results were found lower than the European Union regulatory limits for other foods. To the best of our knowledge, this is among the first studies on dioxin analysis in bee pollen worldwide.

“…whether they constantly monitor pest abundance or they carry out preventive measures and apply insecticides regardless pest abundance. Additionally, it is important to consider the location of our colonies in the agricultural landscape, since its closeness to farms determines the likelihood that bee workers find pesticides [59]; this has yet to be investigated.…”

“…Chauzat et al [66] also pointed out that pollen is the best matrix to determine the presence of pesticides. Moreover, other studies have indicated that the high octanol/water partition coefficient (log Kow) of pesticides allows them to be absorbed by pollen more easily than by honey [59]. Scaptotrigona mexicana pollen and honey samples only resulted positive to 4 and 9…”

In this paper we show the results of investigating the presence of organochlorine pesticides in honey and pollen samples from managed colonies of the honey bee, Apis mellifera L. and of the stingless bee Scaptotrigona Mexicana Guérin. We found that 88.44% and 93.33% of honey samples, and 22.22% and 100% of pollen samples of S. mexicana and A. mellifera, respectively, resulted positive to at least one organochlorine. The most abundant pesticides were DDE, DDT, Endrin and heptaclor. Despite the low foraging range of S. mexicana the number of pesticides detected in the honey samples was similar to that of A. mellifera. Paradoxically we a found a small number of organochlorines in pollen samples of S. mexicana, perhaps indicating a rapid turnover of this material as compared to A. mellifera.

“…Honey bees have been used to detect organic materials such as polychlorinated biphenyls, heavy metals including lead, arsenic, cadmium, and mercury [27][28][29][30], and the dissipation of Cesium-137 years after the Chernobyl accident [31]. It is no surprise that many recent publications have documented multiple pesticides in beeswax, pollen, honey, and bees around the world [5,6,[32][33][34][35][36]. In addition to environmental chemicals, colony matrices may contain chemicals such as antibiotics and miticides used by beekeepers to maintain the health of the bees [37].…”

Potential Risk to Pollinators from Nanotechnology-Based Pesticides

et al. 2019

The decline in populations of insect pollinators is a global concern. While multiple factors are implicated, there is uncertainty surrounding the contribution of certain groups of pesticides to losses in wild and managed bees. Nanotechnology-based pesticides (NBPs) are formulations based on multiple particle sizes and types. By packaging active ingredients in engineered particles, NBPs offer many benefits and novel functions, but may also exhibit different properties in the environment when compared with older pesticide formulations. These new properties raise questions about the environmental disposition and fate of NBPs and their exposure to pollinators. Pollinators such as honey bees have evolved structural adaptations to collect pollen, but also inadvertently gather other types of environmental particles which may accumulate in hive materials. Knowledge of the interaction between pollinators, NBPs, and other types of particles is needed to better understand their exposure to pesticides, and essential for characterizing risk from diverse environmental contaminants. The present review discusses the properties, benefits and types of nanotechnology-based pesticides, the propensity of bees to collect such particles and potential impacts on bee pollinators.
