Persistent Organic Pollutants (POPs) and Polycyclic Aromatic Hydrocarbons (PAHs) in surface sediments from selected fjords, tidal plains and lakes

Abstract: The aim of this study was to examine the pollution level of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and selected chloroorganic pesti− cides (HCH isomers, DDT and its metabolites, aldrin, dieldrin, endrin, heptachlor, endo− sulfan I and II, and methoxychlor...

Description
Summary:Abstract: The aim of this study was to examine the pollution level of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and selected chloroorganic pesti− cides (HCH isomers, DDT and its metabolites, aldrin, dieldrin, endrin, heptachlor, endo− sulfan I and II, and methoxychlor) in surface sediments from selected fjords, tidal plains and lakes from the North Svalbard area. The sediments were collected from 34 sampling sta− tions in July 2005. Only endosulfan I and methoxychlor, among selected chloroorganic pes− ticides, were measured in concentrations near detection limit (LoD) in fourteen sediment samples. The sum of seven PCB congeners varied from < 0.9 to 5.6 ng g−1 d.w. in sediments from fjords and tidal plains and from < 0.1 to 14.6 ng g−1 d.w. in sediments from lakes. The concentrations of analysed PAH compounds in surface sediments from lakes were over ten times higher (16PAHs to 429 ng g−1 d.w.) than in sediments from fjords and tidal plains (16PAHs to 36 ng g−1 d.w.).
