Honeybees as sentinels of microplastic pollution: a meta-analysis of accumulation, toxicity, and biomonitoring potential
AI summary Read the abstract
This review pulled together findings from 139 studies showing that honeybees pick up microplastics (tiny plastic bits) from the environment, and these particles can end up in honey, pollen, and wax, products many people eat or use daily. Because bees fly over large areas and are sensitive to pollution, scientists suggest using them as living "pollution detectors" to track microplastic contamination in the environment, which could also signal risks to the food we eat and the crops bees pollinate. More research is still needed to understand exactly how harmful long-term microplastic exposure is to bees and, by extension, to us.
Microplastics (MPs), tiny plastic particles less than 5 millimeters in size have become a global environmental concern, infiltrating various ecosystems, including those inhabited by honeybees.Here, we synthesized, with a PRISMA approach, the evidence from 139 peer-reviewed studies to critically evaluate (1) the presence of MPs in honeybees and their hive products, such as honey, wax and pollen, (2) the lethal and sublethal effects of MPs in honeybees that in turn potentially impair their pollination services and food security, and (3) given their extensive foraging range and sensitivity to environmental changes, honeybees can serve as effective bioindicators for monitoring MPs pollution.By analyzing the presence of MPs in bees and their hive products, researchers can assess the level of environmental contamination in a given area.Advanced spectroscopic techniques, such as Fourier-transform infrared (FTIR) and Raman spectroscopy, are used for their precision in MPs detection.This review proposes a standardized honeybee-based biomonitoring framework to integrate MPs data into predictive models.Future research must refine MPs detection methodologies, assess chronic exposure impacts on honeybee populations, and translate findings into actionable policy interventions, reinforcing the "One Health" paradigm.In summary, we believe that the interaction between honeybees and MPs is a growing area of research.Understanding how MPs accumulate in bees and their products, assessing the potential health effects on bee populations, and utilizing bees as environmental monitors are crucial steps toward addressing the broader implications of MPs pollution on ecosystems and agriculture.

Microplastics comprehensive review: Impact on honey bee, occurrence in honey and health risk evaluation
AI summary Read the abstract
This systematic review examines how microplastics contaminate honey through bees and their environment. The findings show that bees accumulate microplastics from polluted air, water, and soil, which can then end up in honey — a product many people consume for its health benefits.
Are Honey Bees at Risk from Microplastics?
AI summary Read the abstract
This review examines whether microplastics pose a risk to honey bee populations, noting that microplastics have been detected in honey samples and on bees collected from both urban and rural areas. Researchers found that exposure to certain polymer types may affect bee health, and the study calls for more research to understand the risks of microplastic exposure to pollinators and the broader implications for ecosystem health.
Dancing with danger-how honeybees are getting affected in the web of microplastics-a review
AI summary Read the abstract
This review summarizes research on how microplastics are affecting honeybees, finding that these particles accumulate in bee tissues including the brain, gut, and breathing tubes. Microplastic exposure can change bee behavior, weaken their immune systems, reduce body weight, and disrupt gut bacteria. Since honeybees pollinate roughly 70% of the food crops humans eat, threats to bee health from microplastics could have far-reaching effects on food security.
Microplastics incorporated by honeybees from food are transferred to honey, wax and larvae
AI summary Read the abstract
Researchers found that when honeybees consume food contaminated with microplastics, the particles are transferred to honey, beeswax, and developing larvae inside the hive. Chronic exposure did not significantly affect colony growth, but the presence of microplastics in honey means humans may be ingesting them through this food source. This study reveals another pathway by which microplastics can enter the human diet through contaminated bee products.
Microplastics in honey bees (Apis mellifera): from exposure pathways to mechanistic toxicity, behavioral disruption, and colony-level risks
AI summary Read the abstract
This review summarizes existing research on microplastics in honey bees, found in honey, beeswax, pollen and nectar. Lab studies show microplastics can cause gut damage, stress and possible memory and learning problems in bees, but effects on whole colonies, pollination and human health remain unproven.
