Overview
- University of New England scientists report laboratory evidence that PFOS builds up in European honey bees and can transfer into honey, with findings published in Environmental Science & Technology in February.
- Prolonged sublethal exposure altered expression of key proteins tied to cell function and produced fewer, smaller, lower‑weight next‑generation bees with reduced gland development, including the hypopharyngeal gland that makes royal jelly.
- Potential exposure pathways identified for bees include contaminated dust and water, paint on hives, crop protection products, and pollen from plants grown in polluted soil and water.
- Although PFOS use has been curtailed in many places, researchers warn legacy contamination persists and could undermine colony health, crop pollination and, over time, food security.
- The team plans field studies to trace plant uptake and nectar contamination, notes international detections of PFAS in foraging bees, and says regulators have been contacted for guidance.
