Aerosol trace element analysis using neutron activation and x-ray fluorescence

Throughout the year 1972, air filter samples were collected at Kellogg, Idaho, in the Coeur d'Alene mining district. These samples were analyzed to determine the concentrations of trace metallic elements in the air and to look for indications of their sources - for example, which ones are in the air as a result of the mining and smelting operations, and which are there "naturally" through being picked up by winds from the soil surface. The samples were analyzed for 34 elements using instrumental neutron- activation analysis (INAA), and for six elements using x-ray fluorescence analysis (XRFA). The experimental procedures and results are given here.
