Tunneler i Oslo. Luftkvalitetsberegning i forhold til Forurensningsloven. NILU OR
Forurensning rundt munningene av fire tunneler er beregnet, og situasjonen ved fem andre tunneler er vurdert i forhold til beregningsresultatene. Beregningene viser at ved tilsammen 6 av munningene kan forurensningskonsentrasjon over Forurensningslovens kartleggingsgrense forekomme ved bygninger. Ved en munning forekommer konsentrasjon over tiltaksgrensen ved bygning.

Passive sampling of SO2 and NO2 ambient air concentrations in Cairo. NILU OR
A screening study was undertaken in greater Cairo to check and verify the ambient air pollution monitoring network operated by EIMP/EEAA. The passive samplers were installed in field to measure ground level concentrations in different microenvironments as a result of emissions from traffic and industry. The possibilities for exceeding the EEAA Law no. 4 and the World Health Organisation¿s (WHO) air quality guidelines for SO2 were identified in two areas of Cairo. NO2 concentration limits were high in some selected streets. The passive sampling results compared reasonably well with the permanent network operated by EIMP/EEAA.

he nineteenth mission to Egypt on the DANIDA EIMP programme included further training monitoring programme auditing, QA/QC procedures and reporting. Monthly and Quarterly air quality data reports were produced and presented. Training in QA/QC operations and reporting was given to the Monitoring Laboratories. Results from evaluations at EEAA were reported in Newsletters. Discussions concerning the future air quality measurement programme for Cairo were reported.

For å gjennomføre foreløpig vurdering av luftforurensningen i Norge, etter EUs nye luftkvalitetsdirektiver, var det nødvendig å framskaffe aktuelle data for luftkvalitet i utvalgte mindre byer i tillegg til de 7 største byområdene, som har fast overvåking av luftkvaliteten. Målinger i Lillehammer og Tromsø viste at maksimale konsentrasjoner av PM10 og frekvensen av høye konsentrasjoner var like høye eller høyere enn i de største byene. Dette skyldes antagelig at strøing med sand og grus er en viktig kilde til svevestøv i tillegg til piggdekkslitasje i mindre byer. I de største byene benyttes overveiende salting istedet for strøing på veiene.
