Soil and sediment samples from James Ross Island were analyzed for their PCB, OCP and PAH contents. Soil concentrations ranged between 0.51 and 1.82 ng g−1 for seven indicator PCB congeners, between 0.49 and 1.34 ng g−1 for HCH congeners, between 0.51 and 3.68 ng g−1 for the sum of p,p′-DDT, DDE, and DDD, and between 34.9 and 171 ng g−1 for the sum of 16 EPA PAHs. Sediment levels from 0.32 to 0.83 ng g−1 were found for PCBs, from 0.14 to 0.76 ng g−1 for HCHs, from 0.19 to 1.15 ng g−1 for DDTs, and from 1.4 to 205 ng g−1 for PAHs. A prevalence of low-mass PAHs, less chlorinated PCBs, and more volatile chemicals indicates that the long-range atmospheric transport from populated areas of Africa, South America, and Australia is the most probable contamination source for the solid matrices in James Ross Island.
