. New tests can detect tiny but toxic particles of coal ash in soil « JO LEE MAGAZINE

PHYS.ORG – Scientists at Duke University have developed a suite of four new tests that can be used to detect coal ash contamination in soil with unprecedented sensitivity. The tests are specifically designed to analyze soil for the presence of fly ash particles so small other tests might miss them. Fly ash is part of coal combustion residuals (CCRs) that are generated when a power plant burns pulverized coal. The tiny fly ash particles, which are often microscopic in size, contain high concentrations of arsenic, selenium and other toxic elements, many of which have been enriched through the combustion process.
