The extensive work in AMAP on Arctic contamination by Persistent Organic Pollutants (POPs) illustrates the strong state of knowledge and data on contaminants in biota and water, but also highlights a stark data gap regarding contaminants in Arctic soils, particularly below the permafrost table. Here, we describe the work carried out on analyses and scaling of contaminants. A key aspect for being able to deliver geospatial databases is identifying which landscape properties we can use to scale the measured contaminant levels. Soils in the Canadian study area at Komakuk Beach (Yukon, CA) have been sampled and analysed for hexachlorobenzene (HCB), 54 polychlorinated biphenyl congeners (PCBs) and 22 individual polycyclic aromatic hydrocarbons (PAHs) in 89 active layer and permafrost core samples. The concentrations have been determined by using Thermo Scientific Dionex ASE 350 and Trace 1310 GC coupled with TSQ9000 TQMS, Thermo Scientific, at CNR-ISP Venice, Italy. The statistical parameters of data on HCB ...
