摘要：
Seven sediments cores collected in the Western Ross Sea (Antarctica) were investigated for heavy metals (Cr, Ni, Pb, Cd, Co, Zn Cu and Fe, Mn), several major elements (Ca, Ba and Al), total and organic carbon, and isotopic composition in order to investigate vertical variability. Samples were analyzed by ET-AAS and ICP-AES for metals and by CF-IRMS for carbon content. Generally, concentrations at the background levels were higher with respect to recent ones excluding in this area any kind of anthropogenic contamination. Cluster and Factor Analysis were applied. Best correlations were obtained for the elements showing geochemical affinities.
