Effects of marine mine tailing exposure on the development, growth, and lipid accumulation in Calanus finmarchicus
Svendheim, Linn Hjelmeland; Jager, Tjalling; Olsvik, Pål Asgeir; Øverjordet, Ida Beathe; Ciesielski, Tomasz Maciej; Nordtug, Trond; Kristensen, Torstein; Hansen, Bjørn Henrik; Kvæstad, Bjarne; Altin, Dag; Farkas, Julia (Peer reviewed; Journal article, 2021)Marine tailing disposal (MTD) is sometimes practiced as an alternative to traditional mine tailing deposition on land. Environmental challenges connected to MTD include spreading of fine particulate matter in the water ... -
Effects of mine tailing exposure on early life stages of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus)
Farkas, Julia; Nordtug, Trond; Svendheim, Linn Hjelmeland; D Amico, Elettra; Davies, Emlyn John; Ciesielski, Tomasz Maciej; Jensen, Bjørn Munro; Kristensen, Torstein; Olsvik, Pål Asgeir; Hansen, Bjørn Henrik (Peer reviewed; Journal article, 2021)Mining and processing of minerals produce large quantities of tailings as waste. Some countries, including Norway, allow disposal of mine tailings in the sea. In this study we investigated the impacts of tailings from a ... -
Exposure to low environmental copper concentrations does not affect survival and development in Atlantic cod (Gadus morhua) early life stages
Farkas, Julia; Svendheim, Linn Hjelmeland; Jager, Tjalling; Ciesielski, Tomasz Maciej; Nordtug, Trond; Kvæstad, Bjarne; Hansen, Bjørn Henrik; Kristensen, Torstein; Altin, Dag; Olsvik, Pål Asgeir (Peer reviewed; Journal article, 2021)In this study we investigated potential impacts of Cu exposure at low, environmentally relevant, concentrations on early live stages of Atlantic cod (Gadus morhua). Cod embryos and larvae were exposed to 0.5 μg/L (low), ... -
Omega-3 and alpha-tocopherol provide more protection against contaminants in novel feeds for Atlantic salmon (Salmo salar L.) than omega-6 and gamma tocopherol
Søfteland, Liv Ingeborg Rosvoll; Berntssen, Marc; Kirwan, Jennifer A.; Størseth, Trond Røvik; Viant, Mark.R.; Torstensen, Bente Elisabeth; Waagbø, Rune; Olsvik, Pål Asgeir (Journal article; Peer reviewed, 2016)Extended use of plant ingredients in Atlantic salmon farming has increased the need for knowledge on the effects of new nutrients and contaminants in plant based feeds on fish health and nutrient-contaminant interactions. ... -
Ontogeny-Specific Skeletal Deformities in Atlantic Haddock Caused by Larval Oil Exposure
Olsvik, Pål Asgeir; Sørhus, Elin; Meier, Sonnich; Torvanger, Ingrid; Thorbjørnsen, Maja; Thorsen, Anders; Sørensen, Lisbet; Fjelldal, Per Gunnar; Karlsen, Ørjan; Guimaraes, Igo G.; Lie, Kai Kristoffer (Peer reviewed; Journal article, 2021)Bone deformities are one of the main effects of crude oil exposure in marine fish larvae. Craniofacial and jaw deformities, if severe enough, may restrict feeding and ultimately kill the developing larvae. This study aimed ... -
Sources, distribution and effects of rare earth elements in the marine environment: Current knowledge and research gaps
Piarulli, Stefania; Hansen, Bjørn Henrik; Ciesielski, Tomasz Maciej; Zocher, Anna-Lena; Malzahn, Arne; Olsvik, Pål Asgeir; Sonne, Christian; Nordtug, Trond; Jenssen, Bjørn Munro; Booth, Andy; Farkas, Julia (Peer reviewed; Journal article, 2021)Rare earth elements and yttrium (REY) are critical elements for a wide range of applications and consumer products. Their growing extraction and use can potentially lead to REY and anthropogenic-REY chemical complexes ...
