(NIVA-rapport;0130, Research report, 1965) -
Nestunvassdraget og Apeltunvassdraget i Bergen kommune. En orienterende undersøkelse av forurensningssituasjonen forsommeren 1988
(NIVA-rapport;2416, Research report, 1989)Resipientforholdene i Nestun- og Apeltunvassdraget ble undersøkt i perioden mai til juli 1988. De fysisk-kjemiske undersøkelsene viste at Apeltunvassdraget har en langt bedre bufferkapasitet mot sur nedbør enn Nestunvassdraget ... -
A Neural Network-Based Analysis of the Seasonal Variability of Surface Total Alkalinity on the East China Sea Shelf
(Peer reviewed; Journal article, 2020)Total alkalinity (AT) is an important variable in the regulation of the seawater carbonate chemistry system, determining the capacity to buffer changes in pH. In the coastal oceans, carbonate system dynamics are controlled ... -
Neuroendocrine indicators of allostatic load reveal the impact of environmental acidification in fish
(Peer reviewed; Journal article, 2020)When mobilized from surrounding soils and binding to gills at moderately low pH, aluminum (Al) cations can adversely affect fish populations. Furthermore, acidification may lead to allostatic overload, a situation in which ... -
Neutralisation of hydrogen peroxide after delousing events; technology development and environmental risk assessment
(NIVA-rapport;7635, Research report, 2021)The present project has conducted experiments in laboratory and pilot scale with chemical neutralisation of hydrogen peroxide, which, in combination with technological treatment pose a possible solution for onboard well ... -
New Approach Methodologies for the Endocrine Activity Toolbox: Environmental Assessment for Fish and Amphibians
(Peer reviewed; Journal article, 2023)Multiple in vivo test guidelines focusing on the estrogen, androgen, thyroid, and steroidogenesis pathways have been developed and validated for mammals, amphibians, or fish. However, these tests are resource-intensive and ... -
New Biomarkers
(NIVA-rapport;5214, Research report, 2006)Large volumes of produced water are released into the North Sea and there is still some uncertainty as to the environmental impacts. Following the BECPELAG workshop in 2001-2002, water column monitoring near selected ... -
New brominated flame retardants and dechlorane plus in the Arctic: Local sources and bioaccumulation potential in marine benthos
(Journal article; Peer reviewed, 2018)The aim of the present study was to investigate the presence and bioaccumulation of new flame retardants (nBFRs), polybrominated diphenyl ethers (PBDEs) and dechlorane plus (DDC-CO) in the marine environment close to an ... -
New insights into submarine tailing disposal for a reduced environmental footprint: Lessons learnt from Norwegian fjords
(Peer reviewed; Journal article, 2022)Submarine tailing disposal (STD) in fjords from land-based mines is common practice in Norway and takes place in other regions worldwide. We synthesize the results of a multidisciplinary programme on environmental impacts ... -
New insights into traditional health risk assessments of mercury exposure: Implications of selenium
(Journal article; Peer reviewed, 2014)There is increasing evidence that selenium (Se) has a significant effect on mercury (Hg) toxicology; however, Hg exposure risk assessments usually consider only the amount of Hg present in the environment or in food. On ... -
New microsatellite loci for the green sea urchin Strongylocentrotus droebachiensis using universal M13 labelled markers
(Journal article; Peer reviewed, 2014) -
New Oslo Airport Gardermoen. Biodegradation of the de-icing fluids Kilfrost DF and Clearway 1 in a soil profile
(NIVA-rapport;2797, Research report, 1992)The fate of the de-icing fluids Kilfrost DF (propylene glycol) and Clearway 1 (K-acetate) has been studied in soil lysimeters incubated in the laboratory. Experiments were carried out by 2-4°C and 12-14°C and the water ... -
New Oslo Airport Gardermoen. Biological Treatment of de-icing fluids
(NIVA-rapport;2798, Research report, 1992)During the winter planes and runways have to be sprayed with chemicals to prevent forming of ice. "Kilfros" (planes) and "Clearway" (runways) are the most common de-icing fluids in Norway. They both have a large content ... -
New production across the shelf-edge in the northeastern North Sea during the stratified summer period
(Peer reviewed; Journal article, 2020)New production of organic matter from photosynthesis based on “new” nitrate transported into the illuminated surface layer fuels temperate ecosystems during periods of stratification when surface waters are nutrient limited. ... -
Nikkel og Olivin A/S Utredning av konsekvenser i forbindelse med nytt deponi på Fornes
(NIVA-rapport;4393, Research report, 2001)Nikkel og Olivin A/S har foretatt deponering av flotasjonsavgang i deponier i indre del av Ballangen siden 1988. Resipientundersøkelsene som er foretatt har avdekket en påvirkning av forholdene i indre delen av fjorden ... -
Nikkel og Olivin A/S. Konsekvensanalyse for mineralbryting ved Bruvannsfeltet, Ballangen
(NIVA-rapport;2433, Research report, 1990)Det er utført en konsekvensanalyse av gruvedriften til Nikkel og Olivin A/S i Ballangen. Analysen omfatter virkningen av utslipp til vann, støy, lagring av avfall, risiko ved uhell og virkninger på naturforholdene. ... -
Nikkel og Olivin A/S: Kontrollundersøkelser 1992
(NIVA-rapport;2974, Research report, 1993)Etter at gruvedriften tok til har arsen- og nikkelkonsentrasjonene i Arneselva økt. Dette har både sammenheng med utslipp av gruvevann og redusert vannføring p.g.a. regulering. Metalltransporten fra gruveområdet er relativt ... -
Nipekilen, en tilstandsrapport om forurensningsbelastning
(NIVA-rapport;1616, Research report, 1984)Nipekilen tilføres kloakk og landbruksforurensning. Denne tilførselen fører til stor forurensingsbelastning i kilen. Nipekilens topografi hemmer effektivt utskifting av vannmassene. Resultatet er oksygensvinn og anoksiske ... -
