Arsenic speciation in low-trophic marine food chain – An arsenic exposure study on microalgae (Diacronema lutheri) and blue mussels (Mytilus edulis L.)
Tibon, Jojo; Gomez Delgado, Ana Isabel; Aguera, Antonio; Strohmeier, Tore; Silva, Marta Sofia; Lundebye, Anne-Katrine; Larsen, Martin M.; Sloth, Jens Jørgen; Amlund, Heidi; Sele, Veronika (Peer reviewed; Journal article, 2023)Microalgae and blue mussels are known to accumulate undesirable substances from the environment, including arsenic (As). Microalgae can biotransform inorganic As (iAs) to organoarsenic species, which can be transferred to ... -
Arsenic species in mesopelagic organisms and their fate during aquafeed processing
Tibon, Jojo; Amlund, Heidi; Gomez Delgado, Ana Isabel; Berntssen, Marc HG; Silva, Marta Sofia; Wiech, Martin; Sloth, Jens Jørgen; Sele, Veronika (Peer reviewed; Journal article, 2022)A responsible harvest of mesopelagic species as aquafeed ingredients has the potential to address the United Nations Sustainable Development Goal 14, which calls for sustainable use of marine resources. Prior to utilization, ... -
Assessing mineral availability in fish feeds using complementary methods demonstrated with the example of zinc in atlantic salmon
Silva, Marta Sofia; Stewart, Thea; Amlund, Heidi; Sloth, Jens Jørgen; Araujo, Pedro; Lock, Erik Jan Robert; Hogstrand, Christer; Ørnsrud, Robin; Waagbø, Rune; Prabhu, P. Antony Jesu (Peer reviewed; Journal article, 2021)Assessing the availability of dietary micro-minerals is a major challenge in mineral nutrition of fish species. The present article aims to describe a systematic approach combining different methodologies to assess the ... -
In vitro digestion method to evaluate solubility of dietary zinc, selenium and manganese in salmonid diets
Silva, Marta Sofia; Antony Jesu Prabhu, Antony Jesu Prabhu; Ørnsrud, Robin; Sele, Veronika; Kröckel, Saskia; Sloth, Jens Jørgen; Amlund, Heidi (Peer reviewed; Journal article, 2020)The determination of dietary mineral solubility is one of the main steps in the evaluation of their availability for a given species. -
Selenium and selenium species in feeds and muscle tissue of Atlantic salmon
Sele, Veronika; Ørnsrud, Robin; Sloth, Jens Jørgen; Berntssen, Marc; Amlund, Heidi (Journal article; Peer reviewed, 2018)Selenium (Se) is an essential element for animals, including fish. Due to changes in feed composition for Atlantic salmon (Salmo salar), it may be necessary to supplement feeds with Se. In the present work, the transfer ... -
Speciation analysis of organoarsenic species in marine samples: method optimization using fractional factorial design and method validation
Tibon, Jojo; Silva, Marta Sofia; Sloth, Jens Jørgen; Amlund, Heidi; Sele, Veronika (Peer reviewed; Journal article, 2021)Organoarsenic species in marine matrices have been studied for many years but knowledge gaps still exist. Most literature focuses on monitoring of arsenic (As) species using previously published methods based on anion- and ... -
Speciation of zinc in fish feed by size exclusion chromatography coupled to inductively coupled plasma mass spectrometry – using fractional factorial design for method optimisation and mild extraction conditions
Silva, Marta Sofia; Sele, Veronika; Sloth, Jens Jørgen; Araujo, Pedro; Amlund, Heidi (Journal article; Peer reviewed, 2018)Zinc (Zn) is an element essential to all living organisms and it has an important role as a cofactor of several enzymes. In fish, Zn deficiency has been associated with impaired growth, cataracts, skeletal abnormalities ...
