Abstract

The dispersion model and assessment of air pollution by particulate matter (PM10) are developed in accordance with the requirements of the Bulgarian legislation and the Framework Directive 96/62 / EC on the assessment and management of air quality (AAQ). The input data of the model was based on an assessment of the sources of air pollution in three urban areas of Central North Bulgaria – Svishtov, Sevlievo and Gorna Oryahovitsa, defined as point, area and line sources of PM10.

The results of the modeling and assessment of air pollution in the studied urban areas of Central North Bulgaria for 2007- 2010, show that local air pollution with PM10 from domestic heating of solid fuels is a major factor for dust pollution of air in them.
