Study of Long Range Transported Pollutants in Arctic Soil
In this master thesis, levels of Polychlorinated Biphenyls (PCBs), total organic carbon (TOC) and potentially long range transported inorganic elements (Cd, Hg and Pb) in surface soil and vegetation have been studied for samples from Svalbard (Norwegian Arctic). 74 soil and 35 vegetation samples wer...
