Exposure and effects of emerging and legacy organic pollutants in white-tailed eagle (Haliaeetus albicilla) nestlings
Løseth, Mari Engvig (Doctoral theses at NTNU;2019:175, Doctoral thesis, 2019)Due to long-range transport and high abilities for bioaccumulation and biomagnification, persistent organic pollutants (POPs) are ubiquitous in the environment. Following the ban and legislation of POPs, such as on ... -
Exposure assessment of plastics, phthalate plasticizers and their transformation products in diverse bio-based fertilizers
Estoppey, Nicolas; Varela, Gabriela Castro; Slinde, Gøril Aasen; Hansen, Caroline Berge; Løseth, Mari Engvig; Krahn, Katinka Muri; Demmer, Viona; Svenni, Jørgen; Tran, Teresa-Van-Anh Thi; Asimakopoulos, Alexandros; Arp, Hans Peter Heinrich; Cornelissen, Gerard (Peer reviewed; Journal article, 2024)Bio-based fertilizers (BBFs) produced from organic waste have the potential to reduce societal dependence on limited and energy-intensive mineral fertilizers. BBFs, thereby, contribute to a circular economy for fertilizers. ... -
Feathers as an integrated measure of organohalogen contamination, its dietary sources and corticosterone in nestlings of a terrestrial bird of prey, the northern Goshawk (Accipiter gentilis)
Randulff, Sina Thu; Abbasi, Naeem A.; Eulaers, Igor; Nygård, Torgeir; Covaci, Adrian; Eens, Marcel; Malarvannan, Govindan; Lepoint, Gilles; Løseth, Mari Engvig; Jaspers, Veerle (Peer reviewed; Journal article, 2022)In this study, we evaluated the suitability of body feathers, preen oil and plasma for estimation of organohalogen compound (OHC) exposure in northern goshawk Accipiter gentilis nestlings (n = 37; 14 nests). In addition, ... -

Among the matrices used for OHCs biomonitoring, feathers are particularly useful as they can be ... -
Levels and Effects of Organohalogens on Corticosterone Hormones in glaucous gulls (Larus hyperboreus) from Kongsfjorden, Svalbard
Løseth, Mari Engvig (Master thesis, 2014)Long-range atmospheric transport, ocean currents, sea ice and rivers are transporting environmental contaminants into the Arctic. Some of these contaminants can reach high concentrations in the upper trophic levels in the ... -
Metal concentrations in blood of white-tailed eagle (Haliaeetus albicilla) nestlings and potential effects on metallothionein induction
Marcinekova, Paula (Master thesis, 2019)Environmental pollution with metals in large marine raptors is not a well-studied area, besides for lead poisoning from ammunition. There is a great need for monitoring the evolving trends after several international ... -
