The atmospheric deposition is determined by a variety of factors – the strength and type of the emission sources, transport and diffusion processes, microphysical processes involving aerosols, gases and water droplets, chemical transformation of pollutants, as well as the interaction with different types of earth surface (vegetation, soil, water). One of the key processes, that continue to be of concern on global scale, is the long range transport of pollutants. In fact, the main acidifying substances (sulphates and nitrates) have a residence time in the atmosphere of about 4-7 days, so that they can be transported by atmospheric motions thousands of kilometers away from their sources and impact the environment in regions, far-away from pollution sources.

The focus of this project is on the effects of atmospheric transport processes on deposition of pollutants in Bulgaria. The contribution of long range transport of pollutants depends on the region of air mass and cloud formation. The chemical transformations are different for the various reactive gases and for the aerosols, which leads to fractioning and change in the mass of major ions and trace elements during the transport. The territory of Bulgaria is characterized by highly complex terrain, which determines the interaction of atmospheric processes in different horizontal scales. The precipitation pattern is, accordingly, highly non-homogeneous. The study of such processes from Bulgaria is a challenging task, requiring application of various methods and setting up of various methodologies in order to study atmospheric processes and related ecological problems on a long-term basis.

Project Objectives

The overall goal of the project is to gain new knowledge about the atmospheric deposition of pollutants (including sulphates, nitrates and heavy metals) in Bulgaria and built a scientific base for long-term systematic studies on deposition in a region of Europe, identified as poor in data.

The objectives of the proposed research are:

Expected Results

The expected scientific results are mainly directed to obtain new knowledge for the atmospheric deposition of pollutants over Bulgaria and the processes of atmospheric transport associated with it. In particular:
