摘要: Rare earth elements (REE) levels in Havana bay surface sediments are determined by instrumental neutron activation analysis. REE contents follow the order: Ce > La Nd Sm Eu, Yb, Tb, Lu. The results shows that content is site depended and suggest an anthropogenic input into occurred. chondrite upper continental crust-normalizations confirm enrichment of sediments, respect to from Cuban northwestern coast.
