Benzotriazoles, Benzothiazoles and Trace Elements in an Urban Road Setting in Trondheim, Norway: Re-Visiting the Chemical Markers of Traffic Pollution
Asheim, Johannes; Vike-Jonas, Kristine; Gonzalez, Susana V.; Lierhagen, Syverin; Venkatraman, Vishwesh; Veivåg, Inga-Loise S.; Snilsberg, Brynhild; Flaten, Trond Peder; Asimakopoulos, Alexandros (Journal article; Peer reviewed, 2019)Road traffic emissions are known to contribute heavily to the pollution in urban environments. The aim of this study was to establish specific traffic pollution markers in an urban road setting based on the occurrence ... -
Blood and feather concentrations of toxic elements in a Baltic and an Arctic seabird population
Fenstad, Anette; Bustnes, Jan Ove; Lierhagen, Syverin; Gabrielsen, Kristin Møller; Öst, Markus; Jaatinen, Kim; Hanssen, Sveinn Are; Moe, Børge; Jenssen, Bjørn Munro; Krøkje, Åse (Journal article; Peer reviewed, 2017)Wereport blood and feather concentrations of elements in the Baltic Sea and Arctic population of common eiders (Somateria mollissima). The endangered Baltic Sea population of eiders was demonstrably affected by element ... -
Characterization and bioaccessibility assessment of elements in urban aerosols by extraction with simulated lung fluids
Weggeberg, Hanne; Benden, Tonje Fagertun; Lierhagen, Syverin; Steinnes, Eiliv; Flaten, Trond Peder (Journal article, 2019)Airborne particulate matter (PM) size fractions PM2.5–10 (coarse), PM0.1–2.5 (fine) and PM0.1 (ultrafine) were collected from a site affected by high traffic and a city background site within the city of Trondheim, Norway ... -
Circulating trace elements: Comparison between early and late incubation in common eiders (Somateria mollissima) in the central Baltic Sea
Mcpartland, Molly; Noori, Brenley; Garbus, Svend-Erik; Lierhagen, Syverin; Sonne, Christian; Krøkje, Åse (Peer reviewed; Journal article, 2020)We analyzed body mass and a panel of 64 trace elements in blood from incubating common eiders (Somateria mollissima) in the central Baltic Sea during the breeding seasons of 2017 (n = 27) and 2018 (n = 23). Using a ... -
Elemental content of brown crab (Cancer pagurus) - Is it safe for human consumption? A recent case study from Mausund, Norway
Ervik, Hilde; Lierhagen, Syverin; Asimakopoulos, Alexandros (Peer reviewed; Journal article, 2019)The brown crab (Cancer pagurus; the edible crab) is consumed worldwide and greatly appreciated for the essential elements (e.g., Zn, Se) that it contains. However, alongside these, it contains toxic elements that can pose ... -
Lead concentrations in blood from incubating common eiders (Somateria mollissima) in the Baltic Sea.
Lam, Su Shiung; Mcpartland, Molly; Noori, Brenley; Garbus, Svend-Erik; Lierhagen, Syverin; Lyngs, Peter; Dietz, Rune; Therkildsen, Ole Roland; Christensen, Thomas Kjær; Tjørnløv, Rune Skjold; Kanstrup, Niels; Fox, Anthony D.; Sørensen, Iben Hove; Arzel, Céline; Krøkje, Åse; Sonne, Christian (Journal article; Peer reviewed, 2020)Here we investigate if lead may be a contributing factor to the observed population decline in a Baltic colony of incubating eiders (Somateria mollissima). Body mass and blood samples were obtained from 50 incubating female ... -
Trace element concentrations in feathers and blood of Northern goshawk (Accipiter gentilis) nestlings from Norway and Spain
