Diet and metabolic state are the main factors determining concentrations of perfluoroalkyl substances in female polar bears from Svalbard
Tartu, Sabrina; Bourgeon, Sophie; Aars, Jon; Andersen, Magnus; Lone, Karen; Jenssen, Bjørn Munro; Polder, Anuschka; Thiemann, Gregory W.; Torget, Vidar; Welker, Jeffrey Martin; Routti, Heli Anna Irmeli (Journal article; Peer reviewed, 2017)Perfluoroalkyl substances (PFASs) have been detected in organisms worldwide, including Polar Regions. The polar bear (Ursus maritimus), the top predator of Arctic marine ecosystems, accumulates high concentrations of PFASs, ... -
Effects of a complex contaminant mixture on thyroid hormones in breeding hooded seal mothers and their pups
Grønnestad, Randi; Villanger, Gro Dehli; Polder, Anuschka; Kovacs, Kit M.; Lydersen, Christian; Jenssen, Bjørn Munro; Borgå, Katrine (Journal article; Peer reviewed, 2018)There is a general lack of information on the possible effects of perfluoroalkyl substances (PFASs) on thyroid hormones (THs) in wildlife species. The effects of PFASs, which are known endocrine disruptors, on the TH ... -
Maternal transfer of perfluoralkyl substances in hooded seals
Grønnestad, Randi; Villanger, Gro Dehli; Polder, Anuschka; Kovacs, Kit; Lydersen, Christian; Jenssen, Bjørn Munro; Borgå, Katrine (Journal article; Peer reviewed, 2017)The role of milk in the transfer of perfluoroalkyl substances (PFASs) to offspring is not well known in wildlife. Eight PFASs were quantified in plasma and milk in mother–pup pairs of hooded seals (Cystophora cristata) ... -
Multiple-stressor effects in an apex predator: combined influence of pollutants and sea ice decline on lipid metabolism in polar bears
Tartu, Sabrina; Lille-Langøy, Roger; Størseth, Trond Røvik; Bourgeon, Sophie; Brunsvik, Anders; Goksøyr, Anders; Jenssen, Bjørn Munro; Polder, Anuschka; Thiemann, Gregory W.; Torget, Vidar; Routti, Heli (Journal article; Peer reviewed, 2017)There is growing evidence from experimental and human epidemiological studies that many pollutants can disrupt lipid metabolism. In Arctic wildlife, the occurrence of such compounds could have serious consequences for ... -
Potentiation of ecological factors on the disruption of thyroid hormones by organo-halogenated contaminants in female polar bears (Ursus maritimus) from the Barents Sea.
Bourgeon, Sophie; Riemer, Astrid Kolind; Tartu, Sabrina; Aars, Jon; Polder, Anuschka; Jenssen, Bjørn Munro; Routti, Heli Anna Irmeli (Journal article; Peer reviewed, 2017)As apex predators, polar bears (Ursus maritimus) are among the most heavily polluted organisms in the Arctic. In addition to this anthropogenic stressor, climate warming has been shown to negatively affect their body ... -

U.; Solhaug, Anita; Lyche, Jan Ludvig (Journal article; Peer reviewed, 2019)Human exposure to persistent organic pollutants (POPs) begins during pregnancy and may cause adverse health effects in the fetus or later in life. The present study aimed to assess prenatal POPs exposure to Tanzanian infants ... -
Relationships Between Environmental and Biological Variables, Plasma Clinical-Chemical Parameters and Persistent Organic Pollutants (POPs) in Polar Bears (Ursus maritimus) from Svalbard, Norway
Torget, Vidar (Master thesis, 2015)Few previous studies have reported on levels of clinical-chemical parameters (CCPs) in polar bears (Ursus maritimus), and to date, only one study has investigated levels of CCPs and how they are related to persistent organic ... -
