A method for the measurement of accumulative amounts of atomic mercury vapor in air is described. Devices used for experiments were gold foil (10 cm long, 1 cm wide, 0.1 mm thick), gold wire (10 cm long, 1 mm d.), and quartz tube (4 cm long, 4 mm i. d.) packed with 50 mg of gold coated Chromosorb P. Mercury vapor was collected by simply exposing these devices to air. Mercury collected as amalgam on devices was determined by thermal desorption-flameless atomic absorption spectrometry. Results indicated that the gold foil was the best among these devices for the measurement of accumulative amounts of mercury in air. Mercury collected on a gold foil had a linear relationship with the time of exposure and its relative standard deviation was about 10 %. This method was applied to the measurement of mercury in air near a cement firing plant.
