The nikkel smelters in NW Russia close to the Norwegian border emits large quantities of sulphur dioxide (SO2) and heavy metals. These emissions lead to enhanced concentrations of environmental pollutants in the border areas, also at the Norwegian side of the border. This report is part of the national environmental monitoring program and includes air quality monitoring, precipitation chemistry and meteorology.

SK-1531 Dispersion calculations and HSE evaluation. NILU OR
Norwegian Institute for Air Research (NILU) has performed dispersion calculations of emissions to air from stack SK-1531 at Mongstad refinery. Dispersion of NH3, HCN, CO, CO2, NO2, SO2 and benzene is calculated and analyzed. NILU has also evaluated the calculated concentrations from a HSE point of view, including life time/degradation of the components. The calculated concentrations have been added to existing background concentrations at Mongstad and the calculated total concentrations have been compared to air quality guidelines and threshold values. None of the components investigated here exceed the threshold values. Emissions from SK-1531 is then considered not to represent a problem for the air quality at Mongstad

Air quality impact assessment, Maria Gleta Power Plant, Benin. NILU OR
Concentrations of air pollutants from the 50MW Jacobsen Electro power plant in Benin has been estimated using two different dispersion models. SO2 emissions from the power plant operated with heavy fuel oil has proven to be the most critical option compared to national and international limit values. The SO2 concentrations will never exceed more than 37% of the national air quality limit values. For all other options, such as light fuel oil and gas, the concentrations will be less. Also the impact of NOx and PM10 will be relative to the limit values be less than for SO2. The CO2 emissions will represent less than 10 % of the national greenhouse gas emissions in Benin.
