Project summary

The problems of ecology and protection of environment have become more acute in last decade. There have been a lot of publications, inter-governmental agreements and international projects made in this connection.

Anthropogenic impacts on the environment become comparable with compensative possibilities of nature, evidence of which is the global rise in temperature on the earth.

One of the most serious factors of pollution of the environment is atmospheric pollution by heavy metals, present in the atmosphere as aerosols.

The aim of the project is to carry out research into the content of heavy metals within the atmosphere of Georgia, emission mechanisms, transference and distribution by wind flows.

Both Georgia and the south Caucasus region as a whole are under the influence of the general atmospheric circulation of the central latitudes. In the central latitudes of the northern hemisphere are situated countries with highly developed industries and correspondingly with the highest levels of atmospheric pollution. Research into radioactive atmospheric pollution after nuclear weapon testing and the Chernobyl explosion have shown the existence of maximum levels in the central latitudes.

The geo-morphological structure of the south Caucasus is such that the highest level of global atmospheric pollution comes here.

The level of industrialization of the south Caucasus region is lower than that of other regions of the central latitudes. Localized pollution sources are also less in this region. So here is expected a comparatively low local and high background level of atmospheric pollution. Thanks to this, the south Caucasus region is one of the most favorable regions of the northern hemisphere in which to make studies of the dynamics of global atmospheric pollution. The importance of the results, to be received while the project is working, bear a global character.

Researches, stipulated in the project, are limited by revelation of local sources of heavy metal pollutants on the territory of Georgia, its transference and distribution. Such limitation is within reasonable limits for receiving concrete and certain results, attainable within the framework of one research.

To meet the task requirements, a working team is to be formed with highly qualified specialists of analytical chemistry, mathematical modeling, computing processes, ecology and climatology. Some of the participants have already taken part in similar researches within the framework of “weapon themes”.

The project meets the requirements of ISTC. The above mentioned specialists will use their experience and knowledge for the solution of a global problem – protection of environment.

While carrying out the research, substantial work will be done for the systematization of the results of previous researches (including researches under the seal of secrecy) and meteorological information. Selection of air samples at characteristic points of Georgia as well as thousands of chemical analyses for determination of heavy metals in the content of samples will be arranged.

For the purposes of research into the transference and distribution of pollution a mathematic modeling of these processes will be used.

Definition of methods and results will make it possible to use in the project the latest achievements and approaches.

Great attention will be paid to the precise arrangement of expedition work.

Results will be shown in cadastral data and an atlas of atmospheric pollution of Georgia.
