NASA's Jet Propulsion Laboratory has introduced another method for detecting airborne elemental mercury. When films made of certain polymer/carbon composites are exposed to air containing mercury vapor, their electrical resistances decrease by measurable amounts. The films can be operated and regenerated at mild temperatures.
