Researchers at the University of Graz have shown that honey bees can serve as effective bioindicators for PFAS – per- and polyfluoroalkyl substances – often called “forever chemicals.” These synthetic compounds, found in many everyday products, are harmful to humans and the environment and are difficult to break down.
The study tracked PFAS levels in bees and the pollen they collect across six locations in Upper Austria, Lower Austria, and Styria from April to August, covering urban, semi-urban, rural, and agricultural areas. Researchers found nine different PFAS in 90 samples, with hive bees showing the highest concentrations, followed by forager bees and pollen.
Because bees live only a few weeks, their PFAS levels reflect current environmental contamination, offering a timely snapshot of pollutant distribution. Differences in PFAS levels between sample types suggest multiple exposure routes, including pollen, airborne particles, and contaminated surfaces.
The findings provide crucial data for creating contamination maps and understanding seasonal and location-specific variations in PFAS pollution.
