Occurrence and backtracking of microplastic mass loads including tire wear particles in northern Atlantic air
(Peer reviewed; Journal article, 2023)Few studies report the occurrence of microplastics (MP), including tire wear particles (TWP) in the marine atmosphere, and little data is available regarding their size or sources. Here we present active air sampling devices ... -
Occurrence and seasonality of cyclic volatile methyl siloxanes in Arctic air
(Journal article; Peer reviewed, 2013)Cyclic volatile methyl siloxanes (cVMS) are present in technical applications and personal care products. They are predicted to undergo long-range atmospheric transport, but measurements of cVMS in remote areas remain ... -
Occurrence of emerging brominated flame retardants and organophosphate esters in marine wildlife from the Norwegian Arctic
(Peer reviewed; Journal article, 2022)To understand the exposure and potential sources of emerging brominated flame retardants (EBFR) and organophosphate esters (OPEs) in marine wildlife from the Norwegian Arctic, we investigated concentrations of EBFRs in 157 ... -
Oceanic bromoform emissions weighted by their ozone depletion potential
(Journal article; Peer reviewed, 2015) -
Oceanic long-range transport of organic additives present in plastic products: an overview
(Peer reviewed; Journal article, 2021)Most plastics are made of persistent synthetic polymer matrices that contain chemical additives in significant amounts. Millions of tonnes of plastics are produced every year and a significant amount of this plastic enters ... -
OClO and BrO observations in the volcanic plume of Mt. Etna - Implications on the chemistry of chlorine and bromine species in volcanic plumes
(Journal article; Peer reviewed, 2015) -
Odds and ends of atmospheric mercury in Europe and over the North Atlantic Ocean: temporal trends of 25 years of measurements
(Peer reviewed; Journal article, 2022)The global monitoring plan of the Minamata Convention on Mercury was established to generate long-term data necessary for evaluating the effectiveness of regulatory measures at a global scale. After 25 years of monitoring ... -
OKSIDANTDANNELSE I FORBINDELSE MED UTSLIPP FRA BRENNING AV NATURGASS PÅ OLJEFELTENE I NORDSJØEN.
(NILU OR; 8/86, Research report, 1986)Det er gjort et overslag som viser at utslippene av ikke-metan hydrokarboner og nitrogenoksider i forbindelse med brenning av gass i fakler i Nordsjøen, sannsynligvis er så små at det er liten mulighet for nevneverdig ... -
OM BIDRAG TIL KONSENTRASJONEN AV NO2 OVER OSLO SENTRUM FRA ET VARMEKRAFTVERK VED OSLOFJORDEN
(NILU OR;40/79, Research report, 1979)Innflytelsen av nitrogenoksyd-utslippet fra et varmekraftverk ved Oslofjorden på NO2-konsentrasjonen over Oslo sentrum er vurdert. I tilfeller med vind fra sør kan et oljefyrt varmekraftverk føre til en 50% økning i nåværende ... -
Omregning av EU-kommisjonens forslag til nye grenseverdier, fra prosentilverdier til maksimalverdier.
(NILU OR; 14/98, Research report, 1998)EU-kommisjonen har lagt fram forslag til nye grenseverdier for luftkvalitet for SO2, NO2, PM10 og bly. De nye grenseverdiene, som er prosentilverdier, er omregnet til maksimalverdier på grunnlag av norske måledata de siste ... -
OMSETNING AV SVOVEL OG NITROGEN I ATMOSFÆREN
(NILU OR; 16/83, Research report, 1983)Det er undersøkt hvordan forandringer av engelske utslipp av svoveldioksyd, nitrogenoksyder og hydrokarboner kan påvirke avsetningen av svovel og nitrogenkomponenter over Sør-Skandinavia. Beregningene viser at en 25% ... -
Omvandling og avsetning av nitrogenforbindelser i atmosfæren over hav og kystnære områder.
(NILU OR; 10/95, Research report, 1995)Rapporten inneholder en teoretisk gjennomgang av fotokjemiske reaksjoner og avsetningsprosesser med spesiell vekt på prosesser over hav og kystnære områder. -
On Aethalometer measurement uncertainties and an instrument correction factor for the Arctic
(Journal article; Peer reviewed, 2017) -
ON AIR POLLUTION TRANSPORT TO THE NORWEGIAN ARCTIC.
(NILU OR; 59/85, Research report, 1985)Ground level measurements of sulphate made at Ny Ålesund and Bjørnøya during the period 1979-08-24 through 1984-08-31, has been analysed and used to identify episodes of polluted and clean air in the Norwegian Arctic. By ... -
On coarse patterns in the atmospheric concentration of ice nucleating particles
(Peer reviewed; Journal article, 2023)The atmospheric concentration of ice nucleating particles active at around −10 °C (INP−10) is very low. Nevertheless, these particles play a role in the development of cloud systems, so their spatial and temporal patterns ... -
