Abstract
Results of the field studies, chemical analytical and numerical investigation of the pollution of the snow cover in the zone affected by the sources in Barnaul emitting polycyclic aromatic hydrocarbons (PAHs) are reported. By means of gas chromatography/ mass spectrometry, 19 individual PAH were determined in the collected snow samples. Numerical analysis of the experimental data was performed, and the quantitative regularities of the regional emission of PAHs from the territory of Barnaul were found. By means of the correlation analysis, a linear dependence was established between average logarithms of PAHs concentrations measured in the vicinity of stationary meteorological posts at the territory of the city and beyond its bounds at the direction of prevailing drift. The possibility to construct an economic system of monitoring for estimation of the urban atmospheric pollution for a long-term period was demonstrated.
