From meeting of the Gesellschaft Deutscher Chemiker on trace analysis; Erlangen, Germany (2 Apr 1973). Neutron activation analysis can be applied to the determination of trace elements in airborne dust samples with great advantage, even if the collection time is only a few hours. Cellulose paper filters for collection have proved to contain a particularly small amount of trace elements. Filter efficiencies are satisfactory for most elements. In a short-time irradiation of approximately 1 min in a reactor the elements Se, V, Al, Mg, Br, Cl, In, and Mn can be analyzed quantitatively; in a subsequent long- time irradiation of approximately 1 day, Na, K, Cu, As, W, La, Cd, Au, Sb, Sm, Ca, Fe, Co, Zn, Cr, and Se can be analyzed quantitatively. Airborne dust concentrations for the elements Se, V, Br, Mn, Cu, As, Zn, Fe, Co were determined at the Karlsruhe Nuclear Research Center and close to the motorway between Karlsruhe and Bruchsal. Increased values close to the motorway were encountered only for bromine. Lead as determined by atomic absorption behaves like bromine. (GE)
