Big Question to Developing Solutions: A Decade of Progress in the Development of Aquatic New Approach Methodologies from 2012 to 2022
(Peer reviewed; Journal article, 2023)In 2012, 20 key questions related to hazard and exposure assessment and environmental and health risks of pharmaceuticals and personal care products in the natural environment were identified. A decade later, this article ... -
Bigger is not better: cortisol-induced cardiac growth and dysfunction in salmonids
(Journal article; Peer reviewed, 2017)Stress and elevated cortisol levels are associated with pathological heart growth and cardiovascular disease in humans and other mammals. We recently established a link between heritable variation in post-stress cortisol ... -
Binding grid cells - Norway An evaluation
(NIVA-rapport;3942, Research report, 1998)The quality of the critical load data for so-called "binding grid cells" in Norway has been checked. These are the following EMEP-grids (150km x 150 km): 16,20 16,21 16,30 17,19 17,20 and 18,21. Critical loads have been ... -
Binding of waterborne pharmaceutical and personal care products to natural dissolved organic matter
(Peer reviewed; Journal article, 2021)Information on how key environmental conditions such as natural dissolved organic matter (DOM) and water pH alter the possible risks posed by pharmaceuticals (PPCPs) is still scarce. In our previous study, the presence of ... -
Bio-technological conversion of sludge into organic fertilizers. Sulphate reduction and general sludge treatment
(NIVA-rapport;4555, Research report, 2002)NIVA has been in charge of laboratory tests for converting dissolved metal sulphates in sewage sludge into insoluble sulphides by biological sulphate reduction. We have also had an advisory role related to general engineering ... -
Bioaccumulation and biological effects of cigarette litter in marine worms
(Journal article; Peer reviewed, 2015)Marine debris is a global environmental issue. Smoked cigarette filters are the predominant coastal litter item; 4.5 trillion are littered annually, presenting a source of bioplastic microfibres (cellulose acetate) and ... -
Bioaccumulation and biomagnification of mercury in African lakes: The importance of trophic status
(Journal article; Peer reviewed, 2015)Despite the global prevalence of both mercury (Hg) contamination and anthropogenic eutrophication, relatively little is known about the behavior of Hg in eutrophic and hypereutrophic systems or the effects of lake trophic ... -
Bioaccumulation and trophic transfer of cyclic volatile methylsiloxanes (cVMS) in the aquatic marine food webs of the Oslofjord, Norway
(Journal article; Peer reviewed, 2018)The trophic transfer of cyclic methylsiloxanes (cVMS) in aquatic ecosystems is an important criterion for assessing bioaccumulation and ecological risk. Bioaccumulation and trophic transfer of cVMS, specifically ... -
Bioaccumulation of selected veterinary medicinal products (VMPs) in the blue mussel (Mytilus edulis)
(Journal article; Peer reviewed, 2019)Veterinary medicinal products (VMPs) are widely used within the fish farming industry to control sea lice infestations. There is concern that wild and farmed mussels in the vicinity to these fish farms may be exposed and ... -
