Abstract
The results of field studies, chemical-analytical and numerical investigations of snowpack contamination in the winter season of 2014/2015 in the vicinity of Sovetskoye highway of Novosibirsk after its reconstruction of 2009-2014 years. It was shown that substantial reductions of PAH emissions and the change of the space structure of the field of their fallouts, in comparison with the monitoring data of 2008 were shown. Linear correlations between the precipitation content and that of organic and inorganic components of the samples were established. In the kinematic approximation, the few-parametric model of the field reconstruction of precipitations of the polydisperse impurity from the linear source and the method of its numerical realization in the explicit form was proposed. The approbation of the proposed model on the experimental data obtained was carried out.
