Since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of exposure organohalogen compounds (OHCs) in biota, there has been a considerable number new effect studies. Here, we provide an update on state knowledge OHC, also include mercury, and/or associated key marine terrestrial mammal bird species as well fish by reviewing literature published since AMAP assessment 2010. We aimed at updating how single but combined health are or can be mixtures...
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...
Rapid climate changes are occurring in the Arctic, with substantial repercussions for arctic ecosystems. It is challenging to assess ecosystem remote polar environments, but one successful approach has entailed monitoring diets of upper trophic level consumers. Quantitative fatty acid signature analysis (QFASA) and carbon isotope (δ(13) C-FA) patterns were used East Greenland (EG) bears (Ursus maritimus) (n = 310) over past three decades. QFASA-generated diet estimates indicated that, on...
A well-defined subsample of 128 subadult (3–5 years) polar bears (Ursus maritimus) from 19 sampling years within the period 1984–2006 was investigated for perfluoroalkyl contaminants (PFCs). Linear regression analysis logarithmic-transformed median concentrations showed significant annual increases PFOS (4.7%), PFNA (6.1%), PFUnA (5.9%), PFDA (4.3%), PFTrA (8.5%), PFOA (2.3%), and PFDoA (5.2%). For four PFCs, a LOESS smoother model provided significantly better descriptions, revealing...
There is increasing evidence that the ∼20 routinely monitored perfluoroalkyl and polyfluoroalkyl substances (PFASs) account for only a fraction of extractable organofluorine (EOF) occurring in environment. To assess whether PFAS exposure being underestimated marine mammals from Northern Hemisphere, we performed fluorine mass balance on liver tissues 11 different species using combination targeted analysis, EOF total determination, suspect screening. Samples were obtained east coast United...
Perfluorinated compounds (PFCs), such as perfluorooctane sulfonate (PFOS) and related compounds, have been identified global pollutants shown their bioaccumulation into higher trophic levels in the food chain. PFCs found remote areas far from sources, Arctic. In this study spatial temporal trends concentrations of selected were measured using archived liver samples ringed seal (Phoca hispida) East West Greenland. The collected four different years at each location, between 1986 2003...
