| Summary: | + MODELA survey of soil, sediment and air contamination in James Ross Island, Antarctica serves as a baseline study for evaluation of an anthropogenic impact of the new research facility. 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 g1 for seven indicator PCB congeners, between 0.49 and 1.34 ng g1 for HCH congeners, between 0.51 and 3.68 ng g1 for the sum of p,p0-DDT, DDE, and DDD, and between 34.9 and 171 ng g1 for the sum of 16 EPA PAHs. Sediment levels from 0.32 to 0.83 ng g1 were found for PCBs, from 0.14 to 0.76 ng g1 for HCHs, from 0.19 to 1.15 ng g1 for DDTs, and from 1.4 to 205 ng g1 for PAHs. A prev-alence of low-mass PAHs, less chlorinated PCBs, and more volatile chemicals indicates that the long-range atmospheric transport from popu-lated areas of Africa, South America, and Australia is the most probable contamination source for the solid matrices in James Ross Island. |
