New Study Challenges Assumption of Asbestos' Ability to Move in Soil


A new study led by Scripps Institution of Oceanography at the University of California San Diego scientist Jane Willenbring challenges the long-held belief that asbestos fibers cannot move through soil. The findings have important implications for current remediation strategies aimed at capping asbestos-laden soils to prevent human exposure of the cancer-causing material.Willenbring, along with University of Pennsylvania postdoctoral researcher Sanjay Mohanty, and colleagues tested the idea that once capped by soil, asbestos waste piles are locked in place. Instead they found that dissolved organic matter contained within the soil sticks to the asbestos particles, creating a change of the electric charge on the outside of the particle that allows it to easily move through the soil.
