Summary

Abstract:
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.
