A multiresidue method using dual-injection, dual-column, and dual-micro electron capture detection gas chromatography (dual-column GC-µECD) was developed for the determination of PCB, organochlorine pesticides and chlordanes in marine products. The sample was extracted with hexane-acetone (2 : 1), and the extract was cleaned up by gel permeation chromatography(GPC)/solid-phase extraction (SPE). The GPC fraction was selectively collected, and loaded directly onto a graphitized carbon/PSA 2-layered column. After fractionation by 4% hydrated silica-gel column chromatography, each fraction was determined by dual-column GC-µECD. Recoveries of PCB, organochlorine pesticides and chlordanes were in the ranges of 84-109% (RSD ≤ 21.6%), 74-117% (RSD ≤ 14.6%) and 69-114% (RSD ≤ 12.9%), respectively. This method is superior to single chromatography for the determination of total PCB, and should be useful for monitoring of these pollutants in marine products.

Semi-volatile organic compounds (SVOCs) are widely distributed across the globe, including polar regions. This study investigates the distribution and bioconcentration of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in soils and Colobanthus quitensis, while also estimating potential emission sources. Results indicated high concentrations of PAHs in soils and plants from the Sub-Antarctic region, while OCPs and PCBs were more prevalent in the Antarctic region, with higher contaminant concentrations found in soils than in plant tissues.

The Baltic Sea, a semi-enclosed marginal sea with a catchment area four times its size, acts as a sink and continues to show detectable levels of persistent organic pollutants (POPs) in its sediments. This is attributed to the synthesis and industrial use of commercial polychlorinated biphenyls (PCB) products, as well as the widespread use and discharge of certain chlorinated pesticides into the natural environment during the last century. Our study investigates chlorinated hydrocarbon pollutants, the polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and its metabolites as well as hexachlorobenzene (HCB) in sediments based on several short sediment cores from different basins covering almost the entire Baltic Sea.

The first comprehensive analysis of halogenated organic compounds (HOCs), including 209 full congeners of polychlorinated biphenyls (PCBs), 26 organochlorinated pesticides (OCPs), 41 polybrominated diphenyl ethers (PBDEs), and four other brominated flame retardants (BFRs), was performed on surface mangrove sediments from Bintan Island, Province of the Riau Archipelago, Indonesia. Among the measured HOC contaminants, the mean concentration of ∑PCBs (2.3 ± 0.

Urban environments are exposed to a substantial range of anthropic pressures, including chemical exposure. While trace metals and legacy pollutants have been well documented, the extent of wildlife exposure to emerging contaminants has received little attention, in terrestrial mammals. Concentrations of trace elements (Ag, Al, As, Cd, Co, Cr, Cu, Fe, Mn, Pb and Zn) and 48 organic pollutants (Polychlorinated Biphenyls: PCBs, Organochlorine Pesticides: OCPs, Polycyclic Aromatic Hydrocarbons: PAHs, phthalates and pyrethroid pesticides) were measured in tissues of European hedgehogs (Erinaceus europaeus) in southern Sweden.

Background: Previous studies have demonstrated associations of persistent organic pollutants (POPs) with sex-related hormones; however, findings were inconsistent. Sex-specific impacts and pathways through which adiposity influences associations are not completely understood. We sought to evaluate sex-specific associations of POPs serum concentration with sex-related hormones and to explore pathways through which adiposity may modify associations.
