Scientists have developed a forensic tracer that uses lead isotopes to detect and measure coal fly ash in dust, soil and sediments. Tests show the new tracer can distinguish between the isotopic signature of lead derived from coal ash and lead that comes from other major human or natural sources. Exposure to fly ash from dust, soil or sediments has been linked to numerous diseases and health concerns.
