Field samples and greenhouse experiments suggest these gold particles - which exist at concentrations not harmful to the trees - are absorbed by the roots and transported to its extremities, such as leaves, where the highest concentrations were observed.
X-ray analysis revealed gold particles up to about 8 microns wide in cells from the trees, or about 10 times thinner than the average human hair. Past exploratory drilling revealed these sites had gold buried underground, but the areas were undisturbed by further mining activity that might have contaminated the trees with gold dust.

Researchers investigated leaves, twigs and bark of eucalyptus trees up to 35 feet (10 meters) tall from two locations in Australia - one in the west, another in the south. Now one group has discovered the first evidence in nature of gold particles located within living tissue from trees. However, researchers were not certain until now whether trees could actually absorb the precious metal from underground deposits, or if the wind simply blew gold dust there from other sites. For further information, see Index & Help.Scientists in Australia focused on eucalyptus trees, since traces of gold are sometimes found in soils surrounding these plants.
