Project summaryAs a rule, the operation of uranium mines leads to environmental pollution by waste over a significant area, making this area unproductive for a considerable time. So, the utilization of uranium wastes and the use of soils with a high content of radioactive uranium, heavy and highly toxic elements has significant importance.
Kyrgyzstan is a small, mountainous country, and the problem is double accentuated, as it has places with a high concentration of uranium.
A potential way to use land with a high uranium concentration is to grow agricultural crops, which draw less of it out of the soil, i.e. those with a higher discrimination coefficient.
The Project objectives are to investigate and discover the plants, which take the lowest volume of uranium from the soil, the factors, influencing the reduction of its extraction by plants and animals, and to work out ways of phyto-melioration.
To achieve this aim the following objectives are planned:
1. To study the concentration of uranium in plants and different botanical species, paying special attention to agricultural crops and pasture grasses.
2. Simultaneously, to study its concentration in the soil, where plants grow.
3. To define the discrimination coefficient in the plants.
4. To study the influence of physical-chemical properties on the degree of uranium extraction by the plants.
5. To study the influence of local organic, nitric, phosphoric fertilizers on uranium concentration.
Solving the set objectives will help to learn the general regularity of uranium migration over the soil-plant-animal biological chain in mountainous regions with carbonate residual soil and to elaborate methods to reduce its exposure to plants and animals.
The project belongs to the field of applied research. The investigations permit the development of recommendations for the use of phyto-meliorants in soils with a high uranium concentration, and to elaborate ways to reduce its exposure to animal and human organisms.
The research results could be used in cultivation of agricultural crops, plant cultivation, pasture and meadow cultivation, and as a biological method in the geo-chemical search for uranium deposits.
