(NILU OR; 55/2009, Research report, 2009)Spredningsberegninger for tunnelforbindelsen Hunstadmoen-Thallekrysset i Bodø. Det er beregnet maksimale konsentrasjoner av PM10 og NOX i tunnelen, og minste tilstrekkeligeventilasjonshastigheteri tunnelenfor å overholde ... -
Hydro Aluminium AS. Measurements of CF4 and C2F6 emissions from Norsk Hydro's aluminium smelter at Husnes, Norway.
(NILU report;04/2022, Research report, 2022)NILU and Hydro Aluminium performed a test campaign for measurements of CF4 and C2F6 for stack emissions at Husnes Aluminium Smelter. Time-integrated samples were taken with evacuated canisters combined with low-flow ... -
Hydrocarbon measurements at rural Birkenes, South Norway, May 1987 - May 1988.
(NILU OR; 4/89, Research report, 1989)Analysis of spot samples of air taken approx. every second day at a rural site in south Norway for one year showed that alkanes dominated in the samples. Ethane and propane made up about 50% of the total on a C-basis. The ... -

Hydrolysis of FTOH precursors, a simple method to account for some of the unknown PFAS
(Peer reviewed; Journal article, 2021)There is a growing concern over a suspected presense of unknown perfluoroaliphatic substances (PFAS) in consumer goods and in the environment. Such unknown substances, possibly with high molecular weight, might be precursors ... -
Høyvolumprøvetaking, PUR-prøvetaker.
(NILU TR; 1/96, Research report, 1996)PUR-prøvetakerens usikkerhet er regnet ut ved hjelp av fem parallelle døgnprøver som er analysert med hensyn på PAH. Den beregnede usikkerheten på ca. 10% gjelder således hele PAR-metoden, prøvetaking og analyse. -

IDENTIFICATION OF MODELS FOR SOME TIME SERIES OF ATMOSPHERIC ORIGIN WITH AKAIKE'S INFORMATION CRITERION.
(NILU TN;8/79, Research report, 1979)Akaike's method for model identification has been used to identify "Markov" chain models for simple transformations of daily precipitation at three locations in southeast Norway and wind force and wave height at one location ... -
Identification of POP candidates among chemicals in plastic. Screening for LRTP using the Emissions Fractions Approach.
(NILU report;28/2023, Research report, 2023)There is considerable interest in identifying chemicals which have the potential to undergo long-range environmental transport (LRTP), accumulate in remote regions, and represent a possible risk to environmental and human ... -
Identifisering og vurdering av SFTs overvåkingsdata sett i relasjon til nedbrytning av kulturminner i luft, jord og vann.
(NILU OR;10/99, Research report, 1999)Det foreligger mangelfull kunnskap om de ulike årsakene til nedbrytningen av kulturminner i Norge. En mulig årsak som har vært lite undersøkt her i landet, er i hvilken grad langtransportert luftforurensning og sur nedbør ... -
