“…Seawater samples from the Baltic Sea showed low PCB concentrations (60-400 pg/l), with a reasonably homogeneous distribution and a substantial difference between winter and summer [8,9]. PAH concentration in sub-surface seawater samples from Alexandria's Mediterranean coast ranged between 13 and 120 ng/l [10].…”

The most significant findings on the presence of persistent organic pollutants (POPs) in the marine ecosystem at Ross Sea are presented. Seawater samples were collected in many sampling sites located in a large area of the Ross Sea during various Italian expeditions in Antarctica. Two classes of POPs were considered, namely polychlorobiphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). The results highlighted the presence of these compounds in seawater samples at a total concentration level of about 50 pg/l for PCBs, and 220 pg/l for PAHs. Moreover, seawater samples showed low to high molecular weight PAHs (LMW/HMW) and phenanthrene to anthracene (PHE/ANT) ratios higher than 1 and 5, respectively, which may suggest the predominance of a petrogenic source (i.e. petroleum product contamination). Results were also obtained on the POP depth profile in the water column at Cape Adere, where two water masses converge and mix, i.e. the Modified Circumpolar Deep Water (MCDW) and the High Salinity Shelf Water (HSSW). According to both the PAH and temperature profiles a two-fold higher PAH and PCB concentration was observed for MCDW samples with respect to HSSW. This result represents the first experimental evidence of the external input of pollutants in this area of the Ross Sea coming from the outer oceanic circulation.

Eine Diskussion auf der Grundlage aktueller Untersuchungen der Helsinki-Kommission (HELCOM) [l-81 ie Ostsee ist das grofite und erdge-D schichtlich jiingste Brackwassermeer unseres Planeten. In seiner jetzigen Form existiert es seit etwa 8000 Jahren, als nach der letzten Eiszeit der iiber Nordskandinavien bis zu 3000 m machtige Eispanzer abgeschmolzen war und die damit verbundene Druckentlastung zu einer Landhebung von bis zu 800 m fiihrte. Gleichzeitig mit dieser Hebung stieg jedoch auch der Meeresspiegel. So findet man an der schwedischen Ostseekuste ehemalige Strandwalle und Seeterrassen nur 50-100 m iiber dem heutigen Meeresspiegel der Ostsee und teilweise weit im Landesinneren.
