Black carbon and ionic species in the Arctic aerosol.
Previous studies on Arctic aerosol characteristics have shown a pronounced winter-spring maximum and summer-autumn minimum in aerosol concentration. Measurements of black carbon concentration in the atmospheric aerosol were obtained by means of an aethalometer at the Zeppelinfjellet station Ny-¿lesund, Svalbard. Simultaneous 24 hour measurements of the concentration of key aerosol species like sulphate, ammonium and nitrate together with sulphur dioxide, conducted by NILU are presented and discussed in order to evaluate the transport processes governing their presence in the High Arctic. Large variations are seen to be superimposed on an overall trend that apparently exhibits higher values in winter than in late summer. Back trajectory analysis of the airmasses arriving at Zeppelin station, reveals that enhanced concentrations observed for black carbon and sulphate are associated with long range transport of polluted air from Eurasia. Black carbon, sulphur dioxide and sulphate concentrations are correlated well. Nitrate and ammonium display a rather poor association with the above species and between each other.

Case study of the Nidaros Cathedral in Trondheim. NILU OR
The Nidaros Cathedral has been used as a case study for the "Reach Management System". The two main contributions to the management system has been to obtain direct cost values for maintenance and repair for a historic important building. The second contribution has been on indirect cost, since a willingness to pay study has been performed for the Cathedral. The results from the willingness to pay duly exceeded the average annual budget for the Cathedral with a factor 5.

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.

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.
