Project summary

During the “plan economy” period, over 100 types of pesticides were brought to Kyrgyz republic. When some of them were recognized to be hazardous they were prohibited for production and use. However the surpluses of the prohibited pesticides were not destroyet due to lack of technical means but instead were accumulated, creating a source of environmental pollution. With time passing, the container materials deteriorate, chemical compositions change, resulting in increase of danger. The resulting products are toxic, stable to decomposition, possess bioaccumulative properties, and represent objects of transborder transfer. They are accumulated in the ecosystems of soil and water and, finally, affect human health, resulting in new diseases and congenital anomalies.
At the same time, there is limited information on quantity, quality, and locations of such pesticides storage. According to the operative data of the Department of Chemicalixation and Plants Protection, by the end of 1989 the republican storages had 47.9 tons of prohibited pesticides and by the end of 1994 – 170.8 tons. More precise information can be obtained only through expeditionary inventory of all storage areas of the republic regardless of their form of property, with participation of the representatives of sanitary-epidemiological service, ecologists, and local services of plants protection.
That is why the general objective of this project is reduction, and at a later stage complete elimination, of the danger of environment pollution with these pesticides. The following project tasks are to be fulfilled:
· To conduct inventory of the prohibited and deteriorated pesticides at the storage sites and develop a database;
· To determine their chemical and physical state and toxicity category;
· To determine methods of their utilization and then develop technology of burial and technological documentation;
· To conduct an economical evaluation of the expenditures associated with utilization of such pesticides.

The only organization in Kyrgyz republic that is capable of accomplishing this work is Department of Chemicalixation and Plants Protection. The Department has a staff of professionals with the first-hand experience and knowledge in application of pesticides in the republic. The Department has available sources of information and structure that enable to organize the work on inventory of prohibited and deteriorated pesticides at the storage sites with involvement of the local economists, farms representatives, local sanitary specialists, specialists in plants protection, ecologists, and so on.
The second organization participating in the project is State Scientific Research Institute of Organic Chemistry and Technology (GosNIIOKhT), Moscow, Russia. GosNIIOKhT has unique experience in destruction of highly toxic materials, and is the leading research and development organization in the field of chemical demilitarization. Recently GosNIIOKhT has been conducting research in destruction and utilization of prohibited and deteriorated pesticides on the territory of the Russian Federation. One of such studies was performed in the framework of ISTC project #303 “Neutralization and Following Utilization of Toxic Wastes”. The institute has available all necessary capabilities for running analytical and toxicological studies, corrosion tests, risk analysis as well as development and pilot scale testing of destruction and utilization technologies.
Combining the efforts of these two organizations, Department of Chemicalixation and Plants Protection and State Scientific Research Institute of Organic Chemistry and Technology, for this project is essential for its successful implementation.

Scope of the work include the following tasks:
1. Inventory
1.1. Localization of storage sites
1.2. Transport of samples from sites
1.3. Analytical study of the prohibited pesticides
1.4. Determination of a hazard category for the prohibited pesticides (toxicity)
1.5. Test of pesticides storage containers for corrosion stability
1.6. Systemization of the data in the form of database
2. Development of destruction methods
2.1. Development of methods for particular pesticides
2.2. Analytical support
2.3. Toxicological support
3. Analysis
3.1. Storage risk evaluation
3.2. Technico-economical assessment of destruction methods application
4. Technology development
4.1. Optimization of the parameters at test installations
4.2. Development of technical documentations
4.3. Risk evaluation for burial of pesticides or products of their destruction.

The results of this project will be the following:

· Database reflecting sites of prohibited pesticides storage, amount of pesticides, their status and physicochemical and toxicological characteristics;
· Risk evaluation of storage of pesticides at the sites of their current storage;
· Technology for destruction of the prohibited pesticides including technical documentation;
· Technical-economical and risk evaluation at realization of the technology for destruction of pesticides;
· Recommendations on pesticides destruction.

The results of the project will be used for getting rid of the toxic pesticides.

Successful implementation of this project will contribute to solution of the complex ecological problem of the region.
