DIAZ RIZO, Oscar et al. A study of environmental analysis of havana bay sediments using neutron activation analysis. Nucleus [online]. 2008, n.44, pp. 15-23. ISSN 0864-084X.

ABSTRACT Surface sediments from the Havana Bay (Cuba) were analyzed by instrumental neutron activation analysis (INAA). Concentrations of 23 heavy and trace elements in the sediments were reported, including for the first time, an important group of REE (La, Ce, Nd, Sm, Eu, Tb, Yb and Lu). The normalization of the results for a reference metal shows that an anthropogenic Sb, Ba, As, Cr and Zn inputs are due to discharges of sewage and industrial effluent.
