New tests can detect tiny but toxic particles of coal ash in soil

Scientists have developed tests sensitive enough to detect and measure microscopic particles of coal ash in soil, even at concentrations so low and sizes so small that other tests would likely miss them. The four new tests complement tests previously developed at Duke to detect coal ash contamination in water and larger particles of coal ash in soil.
