Evaluation of Macro- and Microelement Levels in Black Tea in View of Its Geographical Origin
Brzezicha-Cirocka, Justyna; Grembecka, Małgorzata; Ciesielski, Tomasz Maciej; Flaten, Trond Peder; Szefer, Piotr (Journal article; Peer reviewed, 2016)The aim of this study was to evaluate the elemental composition of black tea samples and their infusions in view of their geographical origin. In total, 14 elements were analyzed, 13 (Ca, K, Mg, Na, Mn, Fe, Zn, Cu, Cr, Ni, ... -
Exposure of juvenile turbot (Scophthalmus maximus) to AgNP-EE2 mixtures: Implications on contaminant bioavailability and plasma steroid hormone levels
Farkas, Julia; Salaberria, Iurgi; Styrishave, Bjarne; Stanková, Radka; Ciesielski, Tomasz Maciej; Olsen, Anders Johny; Posch, Wilfried; Flaten, Trond Peder; Krøkje, Åse; Salvenmoser, Willi; Jenssen, Bjørn Munro (Journal article; Peer reviewed, 2017)Combined exposure to engineered nanoparticles (ENPs) and anthropogenic contaminants can lead to changes in bioavailability, uptake and thus effects of both groups of contaminants. In this study we investigated effects of ... -
Hair mineral levels as indicator of wildlife demographics?—a pilot study of muskoxen
Mosbacher, Jesper Bruun; Desforges, Jean-Pierre; Michelsen, Anders; Hansson, Sophia V.; Stelvig, Mikkel; Eulaers, Igor; Sonne, Christian; Dietz, Rune; Jenssen, Bjørn Munro; Ciesielski, Tomasz Maciej; Lierhagen, Syverin; Flaten, Trond Peder; Le Roux, Gael; Aggerbeck, Marie R.; Schmidt, Niels Martin (Peer reviewed; Journal article, 2022)The tight linkage between mineral status and health and demographics in animals is well documented. Mineral deficiencies have been coupled to population declines in wildlife. Current practices typically rely on liver, ... -
