On August 29, 2026, Dr. Agnes Przewozny reported that bumblebees absorb significantly more heavy metals than honeybees, with levels up to seven times higher, even when foraging in the same area. © Jürgen Gräfe Researchers compared honeybees and dark earth bumblebees in identical locations.

Honeybees have long been used as indicators of environmental pollution, including heavy metals, but the transferability of these findings to other bee species has been unclear. While mining, industrial, and urban areas are known to be contaminated with heavy metals, rural regions also see arsenic and cadmium entering soil, plants, and water through pesticides and phosphate fertilizers.
