Abstract
Regular air pollution observations in background areas over the former Soviet Union (FSU) were started in the 1980s. The air background monitoring network consisted of 16 stations working under the Integrated Monitoring (IM) Program. Several air pollutants were monitored at the stations, among them sulfur and nitrogen dioxides, aerosols of sulfate, dust, trace metals, selected pesticides, 3,4-benzopyrene, and ozone. Measurements of sulfur and nitrogen compounds were also continuously taken within the European Monitoring and Evaluation Program (EMEP) at 13 stations located along the western border of the FSU.
The data obtained by the IM and EMEP networks for 1980–95 are the focus of this paper. Western and central regions of the FSU were the most polluted areas. Concentrations for the most part of observed pollutants in Siberia are two–three times less than in the European part of the FSU. At most of the stations, a decrease of sulfur and nitrogen compounds, trace metals, and pesticides concentrations in the air has been observed during the 1980s–90s.
