Title: Distribution of PCBs in Sediment of Terranova Bay and Ross Sea
Marine sediment is frequently used to reconstruct environmental pollution trends. This study regarded the distribution of
PCBs in the sediment from Terra Nova Bay and Ross Sea gathered, during the 1990-1991 expedition. The relevant PCB concentrations
ranged between 30-160 pg g-1, the variability was related to the particle size distribution. The depth profiles of PCB content
in marine sediment samples collected in a few station clearly show that PCBs are confined in a surface layer of about 10
cm. The data were confirmed by results successively presented.
