A LITERATURE SURVEY OF METHODS FOR FRACTIONATED SUSPENDED PARTICULATE MATTER MEASUREMENT
Vitols, Valentin (NILU OR;46/81, Research report, 1981)Literature review suggests the US-type dichotomous sampler (virtual impactor) as the best commercially available device for suspended particle fractionation/gravimetric analysis at this time. The size selective high volume ... -
A TRACER STUDY OF EMISSION PATTERNS FROM GRANGES ALUMINIUM SMELTER IN SUNDSVALL
Sivertsen, Bjarne; Vitols, Valentin (NILU OR;36/80, Research report, 1980)Ten dispersion experiments using SF6 as a tracer were carried out at the Granges Aluminium smelter in Sundsvall during 3-6 June 1980 to recommend locations for representative measurements of ambient PAH in the Sundsvall ... -
AIR POLLUTANTS IN THE ARCTIC. FINAL REPORT OF A RESEARCH PROGRAMME CONDUCTED ON BEHALF OF BRITISH PETROLEUM, LTD.
Ottar, Brynjulf; Gotaas, Yngvar; Hov, Øystein; Iversen, Trond; Joranger, Einar; Oehme, Michael; Pacyna, Jozef M; Semb, Arne; Thomas, Wolfgang; Vitols, Valentin (NILU OR;30/86, Research report, 1986)The present report gives a survey of the work carried out under an arctic research programme financed by British Petroleum Ltd. during the period 1981-86. The composition and origin of the arctic air pollution has been ... -
BAKGRUNNSUNDERSØKELSER AV LUFTFORURENSNINGER VED ALTERNATIVE BYGGESTEDER FOR VARMEKRAFTVERK VED OSLOFJORDEN
Sivertsen, Bjarne; Vitols, Valentin (NILU OR;16/80, Research report, 1980)Det ble i perioden februar 1979-mars 1980 foretatt analyser av luft, nedbør, snø og vegetasjonsprøver rundt alternative byggesteder for et fossilfyrt varmekraftverk ved Oslofjorden. Konsentrasjonene av SO2, sulfat og totalt ... -
CHEMICAL COMPOSITION OF AEROSOLS AT BP PROJECT GROUND STATIONS.
Pacyna, Jozef M; Vitols, Valentin; Hanssen, Jan Erik (NILU OR;64/85, Research report, 1985)Aerosol measurement results are presented for all BP Project ground stations, as well as tentative speculation on the possible source(s). In general, the USSR emission sources are the likely major contributors of particulate ... -
Comparison of virtual impactor and two-filter particle samplers.
Vitols, Valentin; Larssen, Steinar (NILU OR;46/88, Research report, 1988)The two-filter method for samplng of inhalable particles in air has been compared with the virtual impactor method (Dichotomous virtual impactor), which is considered a reference method. The two-filter method correlated ... -
FRAKSJONERT PRØVETAKING AV SVEVESTØV I LUFT. SAMMENLIGNING AV PRØVETAKERE, 1982.
Larssen, Steinar; Vitols, Valentin (NILU OR;67/86, Research report, 1986)Tre typer prøvetakere for inhalerbare partikler (d < 15 μm) ble sammenlignet ved målestasjoner i Oslo og Lillestrøm i perioden juli-oktober 1982. Prøvetakerne var: "Dichotomous virtual impactor", "High volume sampler w/size ... -
METODER FOR MÅLING AV RESPIRABLE PARTIKLER OG NITROGENOKSYDER I ARBEIDSATMOSFÆREN
Wathne, Bente M.; Vitols, Valentin; Hanssen, Jan Erik (NILU OR;9/80, Research report, 1980)Metoder for måling av respirable partikler og NOX er sammenlignet under en ukes måleperiode ved Kværner Brug A/S i Oslo. Det er også utført sporgassforsøk med SF6 for å bestemme utluftingen i arbeidslokalet. -
ON THE SUITABILITY OF "BADGE" AIR SAMPLERS FOR HUMAN EXPOSURE ASSESSMENT
Vitols, Valentin (NILU OR;1/82, Research report, 1982)A brief literature scan suggests that personal monitoring of human exposures to air pollutants is essential in health impact assessment. Passive personal exposure monitoring devices (PEMs) are simple, inexpensive, rugged, ... -
SPECIAL MEASUREMENTS AT NY ÅLESUND: PHYSICAL AND CHEMICAL PROPERTIES OF THE ARCTIC AEROSOL.
Vitols, Valentin; Pacyna, Jozef M (NILU OR;65/85, Research report, 1985)Physical and chemical properties of the arctic aerosol at Ny Ålesund, Spitsbergen, have been studied during the arctic winter and summer seasons. Size-differentiated chemical composition of aerosols has been used to assess ...
