Safety Concerns Over Tungsten Accumulation in Bone

03/08/2018

New research shows how and where tungsten, which has been associated with childhood lymphocytic leukemia, accumulates in the bones of mice exposed to the element through drinking water. X-ray fluorescence spectroscopy showed that tungsten accumulated in bone tissue, with some sites having ~10-fold greater intensities than background levels. The findings raise doubts over the once-universal assumption that tungsten poses little or no health risk to the general human population.
