AB Persistent organic pollutants (POPs) bioaccumulate in biota, have long residence times in the environment,and potential for long range atmospheric transport. Here, we show the first measurements oflegacy POPs in the atmosphere of the Antarctic Plateau from 73 South to the South Pole. Samples weretaken using passive samplers. The amount of polychlorinated biphenyls (as P26PCBs) per sample rangedfrom 0.8 ng to 26 ng. The mass per sample of hexachlorobenzene (HCB) and g-hexachlorocyclohexane(g-HCH) in the gas-phase ranged from 0.67 ng to 2.7 ng and from non-detected to 2.6 ng, respectively.The lowest amounts of POPs were observed at the South Pole. This work shows that POPs have alsoreached the remotest region of Earth from primary sources. The assessment of the air mass back trajectories and current knowledge of atmospheric circulation over the Antarctic continent suggests thatPOPs reach the Antarctic Plateau by subduction of air masses from the free troposphere.
