Abstract

A comparative analysis was carried out of pollutants content distribution models in the air of Kyiv, with the most plausible estimates of the parameters, such as normal, lognormal, composite with normally distributed local ingredients, and composite with lognormal local ingredients. It is shown that the latter two models can produce stable estimates of areas where critical limits of harmful substances are above the norm. The assessments in Kyiv were made in period of 2001 trough to 2010. It is shown that the state of air pollution in Kyiv from 2001 to 2010 has worsened, especially as regards dust, sulfur dioxide and nitrogen dioxide.
