Non-target and suspect screening of volatile organic compounds from Scots pine and Norway spruce building materials

Bakke, Ingrid Marie; Kallenborn, Roland; Nyrud, Anders Q.; Håland, Alexander

Wood building materials can be a source of volatile organic compounds (VOCs) in the indoor environment and increasing focus is put on classification and regulation of the use of wood building materials in Europe. The main wood related VOCs such as monoterpenes rarely pose adverse health effects for humans, but as analytical procedures become more sensitive new hazardous VOCs are detected in low concentration. There is a need for comprehensive identification of VOCs emitting from different wood building materials for indoor use. This study performed a first semi-quantitative non-target and suspect screening of VOC emissions from three important wood-based building materials in Europe. Air samples collected from emission chambers were analyzed using comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry and resulting mass spectra were classified into confidence groups. A total of 84, 133 and 197 compounds were found to emit from cross-laminated timber, untreated spruce panel and untreated pine panel, respectively. Pine panel was found to emit a higher number of VOCs as well as higher concentrations of most VOCs compared to the spruce building materials. Several new VOCs were detected in the emission profile of pine and spruce. However, they were mostly structurally similar to previously reported wood VOCs. Two compounds of concern emitting from all three wood building materials were furfural and (E)-2-octenal, as these have been classified as group 2 carcinogen and potent eye irritant, respectively.

NO2-beregninger for 2010 og 2025 i Oslo og Bærum. Bidrag fra dieselbiler og mulige tiltak . NILU OR

Sundvor, I.; Tarrasón, L.; Walker, S-E.; Tønnesen, D.

Luftkvaliteten i Oslo i 2025 vil bli verre enn tidligere antatt. Hvis dagens bilsalgstrend med høy andel nye dieselbiler fortsetter og man tar hensyn til utslipp fra dieselbiler i reelt kjøremønste r, vil NO2 -bidraget fra personbiler øke i 2025 i forhold til 2010. Våre scenarioberegninger viser at dagens bilsalg vil medføre omfattende overskridelser av luftkvaliteten i lang tid fremover.
Beregninger er gjort for to år: 2010 og en fremskrivning til 2025. Totalt vises resultat av 9 spredningsberegninger. Først presenteres det resultat fra 4 referanseberegninger som viser økning i NO2 konsentrasjoner når vi tar hensyn til forskjellen mellom etablerte og oppdaterte utslippsfaktorer som er basert på målinger under reelle kjøremønstere. Rapporten presenterer også resultat fra tre tiltaksberegninger for 2025, med forskjellige insentiver for reduksjon av bruk av dieselbiler, og to ulike strakstiltak for bruk av datokjøringer. Innføring av disse forskjellige tiltakene blir ikke tilstrekkelig for å holde grenseverdiene i Oslo og Bærum i 2025.
