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, ... -
In ovo transformation of two emerging flame retardants in Japanese quail (Coturnix japonica)
Briels, Nathalie; Løseth, Mari Engvig; Ciesielski, Tomasz Maciej; Malarvannan, Govindan; Poma, Giulia; Kjærvik, Sara Alainezhad; Léon, Alexis; Cariou, Ronan; Covaci, Adrian; Jaspers, Veerle (Journal article; Peer reviewed, 2018)Tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) and Dechlorane Plus (DP) are two chlorinated, alternative flame retardants that have been found in wild birds and bird eggs. Little is known about the fate and effect of these ... -
Integrated exposure assessment of northern goshawk (Accipiter gentilis) nestlings to legacy and emerging organic pollutants using non-destructive samples
Briels, Nathalie; Torgersen, Lene Norstrand; Castaño-Ortiz, Jose M.; Løseth, Mari Engvig; Herzke, Dorte; Nygård, Torgeir; Bustnes, Jan Ove; Ciesielski, Tomasz Maciej; Poma, Giulia; Malarvannan, Govindan; Covaci, Adrian; Jaspers, Veerle (Journal article; Peer reviewed, 2019)In the present study, concentrations of legacy and emerging contaminants were determined in three non-destructive matrices (plasma, preen oil and body feathers) of northern goshawk (Accipiter gentilis) nestlings. Persistent ... -
Organophosphate esters in indoor dust from 12 countries: Concentrations, composition profiles, and human exposure
Li, Wenhui; Asimakopoulos, Alexandros; Covaci, Adrian; Gevao, Bondi; Johnson-Restrepo, Boris; Kumosani, Taha Abdullah; Malarvannan, Govindan; Moon, Hyo-Bang; Nakata, Haruhiko; Sinha, Ravindra K.; Tran, Tri Manh; Kannan, Kurunthachalam (Journal article; Peer reviewed, 2019)A total of 20 organophosphate triesters (OPEs), including seven alkyl-OPEs, three chlorinated (Cl)-OPEs, seven aryl-OPEs, and three oligomeric-OPEs were measured in 341 house dust samples collected from 12 countries during ... -
Plasma concentrations of organohalogenated contaminants in white-tailed eagle nestlings – The role of age and diet
Løseth, Mari Engvig; Briels, Nathalie; Eulaers, Igor; Nygård, Torgeir; Malarvannan, Govindan; Poma, Giulia; Covaci, Adrian; Herzke, Dorte; Bustnes, Jan Ove; Lepoint, Gilles; Jenssen, Bjørn Munro; Jaspers, Veerle (Journal article; Peer reviewed, 2019)Concentrations of organohalogenated contaminants (OHCs) can show significant temporal and spatial variation in the environment and wildlife. Most of the variation is due to changes in use and production, but environmental ... -
Temporal trends of legacy organochlorines in different white-tailed eagle (Haliaeetus albicilla) subpopulations: A retrospective investigation using archived feathers
Sun, Jiachen; Covaci, Adrian; Bustnes, Jan Ove; Jaspers, Veerle; Helander, Björn; Bårdsen, Bård-Jørgen; Boertmann, David; Dietz, Rune; Labansen, Aili Lage; Lepoint, Gilles; Schulz, Ralf; Malarvannan, Govindan; Sonne, Christian; Thorup, Kasper; Tøttrup, Anders P.; Zubrod, Jochen P.; Eens, Marcel; Eulaers, Igor (Peer reviewed; Journal article, 2020)Understanding the spatiotemporal patterns of legacy organochlorines (OCs) is often difficult because monitoring practices differ among studies, fragmented study periods, and unaccounted confounding by ecological variables. ... -
White-tailed eagle (Haliaeetus albicilla) feathers from Norway are suitable for monitoring of legacy, but not emerging contaminants
Løseth, Mari Engvig; Briels, Nathalie; Flo, Jørgen; Malarvannan, Govindan; Poma, Giulia; Covaci, Adrian; Herzke, Dorte; Nygård, Torgeir; Bustnes, Jan Ove; Jenssen, Bjørn Munro; Jaspers, Veerle (Journal article, 2018)While feathers have been successfully validated for monitoring of internal concentrations of heavy metals and legacy persistent organic pollutants (POPs), less is known about their suitability for monitoring ofemerging ...
