Twelve Elements (Ca, Cr, Mn, Co, Ni, Zn, As, Br, Cd, Sn, Sb, Pb) in airborne particulate samples were analysed with help of an electron linear accelerator. Analyses were carried out instrumentally. The air dust filters were pressed to pellets and irradiated for approximately five hours. Eleven of the named elements were activated with high energy bremsstrahlung and one (Mn) with photoneutrons. Samples were taken over a one year's period (spring 1981 to spring 1982) in different types of location (rural and urban, residential and industrial) within the Federal Republic of Germany.
