The main purpose of mission 16 was to introduce a new technique for analysis of volatile organic compounds (VOC) in air samples, and to do on the job training of the staff at Centre for Environmental Hazards Mitigation (CEHM) at the Cairo University, Giza. Due to major changes in staff at the laboratory during the visit, it was not possible to complete the training program according to the original plan. The equipment for sampling and analysis has been checqued and tested and further needs of equipment has been evaluated.

Assessment of emissions/ discharges of mercury reaching the Arctic environment. NILU OR
Our knowledge of mercury fluxes on a global scale is still incomplete. The above presented estimates for Europe and North America seem to contribute less about 25 % to the global anthropogenic emissions of the element to the atmosphere. The majority of the remaining emissions originate from combustion of fossil fuels, particularly in the Asian countries including China, India, and South and North Korea. Even less and very controversial information is available on emissions of mercury from natural sources, including volatilization of the element from terrestrial and aquatic surfaces. In general, it is assumed that natural emissions of the element are about 3000 t/year, thus contributing more 60 % to the total global emissions of mercury. However, much work needs to be done in order to verify the above estimate.

The fifteenth mission to Egypt on the DANIDA EIMP programme included monitoring programme updating, QA/QC procedures, training and reporting. Air pollution episodes resulted in daily reporting procedures. Monthly and Quarterly air quality data reports were produced and presented. Training in QA/QC operations was given to the Monitoring Laboratories. Audits to the monitoring stations was performed as part of training given to the Reference Laboratory. Results were reported in Newsletters, Memos and in a paper presented at the international conference Environment '99.

A comprehensive study of the occurrence and extent of air pollution along the Russion border in Sør-Varanger county started in 1988. -The measurement programme includes air quality, meteorological conditions and precipitation chemistry. The highest SO2 -concentrations in Norway are measured in this area. The smelters in Nikel and Zapoljarnij are the main sources of SO2 in the area.

The NILU aircraft plume model: A technical description. NILU TR
The NILU-aircraft plume model combines the chemical and physical evolution in an aircraft plume. It describes the plume within a day after emissions. This report gives a detailed description of the plume dispersion, the diffusion within the different layers of the plume and the tropospheric chemistry scheme used in the model.
