A TRACER INVESTIGATION OF A LABORATORY VENTILATION SYSTEM.
(NILU TN;8/78, Research report, 1978)Several SF6 tracers tests were conducted within a laboratory-office building in order to investigate the building ventilation system. This work serves as a demonstration of how tracer techniques can be used to characterize ... -
A tracer study of the ventilation system in NILUs new building.
(NILU TR; 15/94, Research report, 1994)This report describes a tracer study of the ventilation system in NILU' s new building. The tracer SF6 is used to measure the air exchange in selected rooms and in two of the five ventilation subsystems in the building. ... -
AIRBORNE MEASUREMENTS OVER SKAGERRAK 29 JANUARY 1981
(NILU TN;5/81, Research report, 1981)To study the chemistry of power station plumes, tracer material is released from a station in England. An English aircraft observed measurable concentrations along the west coast of Denmark. NILU undertook aircraft sampling ... -
ATMOSPHERIC DISPERSION EXPERIMENTS USING THE NILU AUTOMATIC WEATHER STATION AND SF6 TRACER TECHNIQUES.
(NILU TN;12/78, Research report, 1978)Rapporten beskriver NILUs automatiske værstasjon (AWS), samt NILUs utstyr for sporstoffundersøkelser. Den presenterer resultatene fra spredningsforsøk for å finne sammenhengen mellom spredningsparametre til gaussmodeller ... -
EMISSION FACTORS OF TRACE METALS FROM COAL-FIRED POWER PLANTS
(NILU TN;14/81, Research report, 1981)The emission factors of trace metals are established for different types of power stations, using enrichment factors of these pollutants in the flue gas stream and technological data of boilers and dedusting installastions. ... -
Multi-element ICPMS analysis of moss used as biomonitor of air pollutants.
(NILU TR; 1/95, Research report, 1995)The analysis techniques ICPMS is studied for the determination of major and trace elements in mosses used as biomonitors for atmospheric trace metal deposition. Good accuracy and precision are documented by analysis of ... -
NEDSLAGET AV FORURENSNINGER I TURBULENSOMRÅDET BAK EN ALUMINIUMHALL. EN UNDERSØKELSE VED HJELP AV SPORSTOFF.
(NILU TN;9/78, Research report, 1978)Dette tekniske notat er et norsk sammendrag av oppdragsrapport 26/78 "A TRACER INVESTIGATION OF THE WAKE DOWNWIND OF AN ALUMINIUM SMELTER HALL". Undersøkelsen ble utført av NILU i samarbeid med A. Milde, O. Rørvik og H. ... -
SPREDNINGSFORSØK MED SF6 OG CBRF3 FOR Å STUDERE RELATIVE FORURENSNINGSBIDRAG FRA OLJEFYRING OG BILTRAFIKK.
(NILU TR;9/86, Research report, 1986)Rapporten beskriver spredningsforsøk med SF6 og CBrF3 på Lillestrøm og i Oslo. SF6 og CBrF3 er sluppet henholdsvis gjennom skorstein og ved bakken for å simulere spredning fra oljefyring og biltrafikk. Resultatene indikerer ... -
THE CHEMICAL COMPOSITION OF AEROSOLS IN ZABADANI VALLEY, SYRIA.
(NILU TR;18/85, Research report, 1985)The chemical composition of aerosols measured during a short period in 1985-08 in Zabadani Valley, near Damascus, Syria, is presented. Very high concentrations of several anthropogenic elements in some samples indicate ... -
THE INFLUENCE OF CAR SPEED ON DISPERSION OF EXHAUST GASES.
(NILU TR;6/86, Research report, 1986)Dispersion of exhaust gases by an open road is mapped in seven tracer experiments. Two cars emitting SF6 and CBrF were driven with different speed emitting one tracer component each. The dispersion by the road increased ... -
UNDERSØKELSER AV SPREDNINGSFORHOLDENE VED ALUMINIUMVERKET I HØYANGER.
(NILU TN;10/78, Research report, 1978)Spredningsforholdene i Høyanger er undersøkt ved hjelp av sporstoff (SF6), pilotballonger, radiosonder og registrerende meteorologiske stasjoner. Resultatene fra 12 spredningsforsøk er presentert. Konsentrasjonen av SO2 ...
