Laboratoire Central d'Analyse, Centre Régional d'Etudes Nucléaires de Kinshasa, Zaïre.

Instrumental neutron activation analysis was performed to assess the exposure degree of a worker group from a copper smelter. The results were compared with data of inhabitants of Kinshasa and Bandaka in Zaire. Excessive concentrations of Mg, Ca, V, Co, Cu, As, and Cd were observed in the investigated group. The distribution patterns of trace elements are shown. The plots of Cu concentration relations to selected elements, i.e., As, Co, and Zn, showed a plateau at about 300 ppm of Cu.
