Abstract
Per- and polyfluorinated chemicals (PFASs) are very toxic industrial compounds, and fewer studies have been conducted on their presence in the sedimentary environment of the polar region. The present study is a preliminary assessment of the concentration and distribution of PFOA (Perfluorooctanoic acid) in selected fjord systems of the Svalbard archipelago, Norwegian Arctic. The ∑PFOA observed for Smeerenburgfjorden, Krossfjorden, Kongsfjorden Hotmiltonbuktafjorden, Raudfjorden and Magdalenefjorden were 1.28 ng/g, 0.14 ng/g, 0.68 ng/g, 6.54 ng/g, 0.41 ng/g and BDL respectively. Of the twenty-three fjord samples studied, the sediments from Hotmiltonbuktafjorden exhibited the presence of a higher concentration of PFOA in the sediment matrices. More studies are needed to understand their fate in the sedimentary environment with respect to the physio-chemical properties of the sediments.
