Poly- and perfluoroalkyl substances (PFASs) are important environmental contaminants globally in the early 2000s they were shown to be ubiquitous Arctic wildlife. Previous reviews by Butt et al. Letcher have covered studies on levels trends of PFASs that available 2009. The purpose this review is focus more recent work, generally published between 2009 2018, with emphasis emerging concern such as carboxylates (PFCAs) short-chain sulfonates (PFSAs) their precursors. Atmospheric measurements...
The Arctic ecosystem receives contaminants transported through complex environmental pathways – such as atmospheric, riverine and oceanographic transport, well local infrastructure. A holistic approach is required to assess the impact that plastic pollution may have on Arctic, especially with regard unseen microplastics. This study presents data microplastics in fjords of western Svalbard, by addressing ecological consequences their presence coastal surface waters sediment, non-invasive...
The presence of unidentified organofluorine compounds (UOF) has been investigated in recent publication, but their environmental occurrence is still poorly understood. Fluorine mass balance analysis was performed on samples from lake Mjøsa and river Alna (surface water (n = 9), sediment 5) fish liver 4)) sewage Oslo 5), to reveal the fraction UOF. In that had extractable (EOF) concentrations above limit detection (LoD), more than 70% EOF could not be accounted for by 37 PFAS monitored this...
Pharmaceutical deltamethrin (Alpha Max), used as delousing treatments in aquaculture, has raised concerns due to possible negative impacts on the marine environment. A novel approach combining different scientific disciplines addressed this topic. Acute (mortality) and sublethal effects (i.e., fitness, neurological, immunological, oxidative responses) of exposure northern shrimp (Pandalus borealis) were studied laboratory experiments. Passive water sampling combined with sediment analyses...
Considerable amounts of previously deposited persistent organic pollutants (POPs) are stored in the Arctic cryosphere. Transport freshwater and terrestrial material to Ocean is increasing due ongoing climate change impact this has on POPs marine receiving systems unknown This study investigated how secondary sources from land influence occurrence fate an coastal system. Passive sampling water riverine suspended particulate matter (SPM) sediments for analysis polychlorinated biphenyls (PCBs)...
Climate change-driven increases in air and sea temperatures are rapidly thawing the Arctic cryosphere with potential for remobilization accumulation of legacy persistent organic pollutants (POPs) adjacent coastal food webs. Here, we present concentrations selected POPs zooplankton (spatially seasonally), as well zoobenthos sculpin (spatially) from Isfjorden, Svalbard. Herbivorous contaminant were highest May [e.g., ∑polychlorinated biphenyls (8PCB); 4.43, 95% CI: 2.72-6.3 ng/g lipid weight],...
Enantiomeric fractions (EF) are today considered a powerful tool to elucidate selective uptake processes of chiral contaminants in biota. In this study, concentration levels and EF were determined by gas chromatograph–mass spectrometer (GC/MS) for α-hexachlorocyclohexane (α-HCH) trans-, cis-, oxychlordane selected Greenlandic traditional food items, collected at the local market Nuuk 2010. The items raw smoked fish (salmon halibut, n = 6), whale meat (n 8), seal 2) narwhal mattak (skin...
Livers of caribou and reindeer (Rangifer tarandus) from Canada (n = 146), Greenland 30), Svalbard 7), Sweden 60) were analyzed for concentrations eight perfluoroalkyl carboxylic acids four perfluoroalkane sulfonic acids. In Canadian caribou, PFNA (range < 0.01-7.4 ng/g wet weight, ww) PFUnDA (<0.01-5.6 dominated, whereas PFOS predominated in samples South Greenland, Svalbard, Sweden, although the highest found Southwest (up to 28 ww). We median all PFAS except PFHxS Akia-Maniitsoq (Southwest...
A pilot study is presented evaluating selected chlorinated pesticides as chemical tracers for water masses in a sub-Arctic fjord system (Godthåbsfjord, western Greenland). Polyoxymethylene (POM) based passive samplers were deployed during summer–autumn 2010. The levels of the analysed surface waters found to be low compared earlier studies. α-Hexachlorocyclohexane (α-HCH) and hexachlorobenzene (HCB) predominant contaminants. However, these two compounds have higher oceanic freshwater...
