dc.description.abstractAn Expert Group on Studies of Local Air Pollution Problems was established in 1988 under the Joint Norwegian-Soviet Commission on Environmental Co-operation. This group has been responsible for a joint monitoring and evaluation programme in the border areas of the two countries. Scientists from the Norwegian Institute for Air Research (NILU) and from the Institute of Industrial Ecology Problems of the North (INEP) at the Kola Science Centre, have been responsible for the intercalibration, data collection, modelling and evaluation. The air pollution in the border areas are dominated by episodes linked to adverse meteorological conditions. During these episodes the concentrations of SO2 have exceeded national and international guideline values by a factor of ten at distances of up to 30 km from the smelter industries in Nikel and Zapoljarnij. These smelters represent the main sources of air pollution in the area. Exceedance of seasonal average SO2 concentration guide-line values was found in an area covering about 2000 km2 in winter and 700 km2 in summer. The deposition of the heavy metals Ni and Cu also exceeded background values by a factor of ten or more within the first 10-30 km from the smelters. To obtain an air quality which will not exceed given critical level values, the emissions of SO2 have to be reduced by 90 to 98%.
