摘要：The presented study of the PM10 concentrations in the atmosphere ground layer emitted from industrial sources in the Industrial zone in the city of Ruse in the days with exceedances for this pollutant is aimed to determining the possibility of cross-border BG-RO PM10 contamination. Climatic conditions measured in these days with PM10 exceedances in January 2017 are also taken into account in Jet Gauss model and in the Langrageo-statistical approach for describing the turbulent diffusion. The results show that the PM10 pollutant from the investigated sources in industrial zone in Ruse is reaching the territory of Republic of Romania with low concentrations and have no potential for impact on air quality in the cross-border area.
