Polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in Antarctic ice-free areas: Influence of local sources on lakes and soils
Antarctica is usually considered a pristine ecosystem; nevertheless it is influenced by Persistent Organic Pollutants (POPs),mainly driven by long-range atmospheric transport (LRAT). However, localized sources such as human and wildlife activities can also contribute to pollution, constituting conta...

Antarctica is usually considered a pristine ecosystem; nevertheless it is influenced by Persistent Organic Pollutants (POPs),mainly driven by long-range atmospheric transport (LRAT). However, localized sources such as human and wildlife activities can also contribute to pollution, constituting contaminated points at a local scale. Antarctic ice-free areas, where rare lakes are located, are influenced by such sources. In this work we determine polychlorinated biphenyls (PCBs, including the non-Aroclor CB-11) and polybrominated diphenyl ethers (PBDEs) in water and sediment samples of 6 lakes in Northern Victoria Land and in soils near the Italian research station Mario Zucchelli.
