Project summaryThe purpose of the Project is to study and organize monitoring of contamination with toxic elements – zinc, copper, arsenic and residual amounts of persistent pesticides – DDT, hexachloran-cyclohexane, HCCH, gamma-HCCH, zineb, ziram, atrazine, simazine – of Georgia’s agricultural plants and soils.
Another purpose of the Project is to reveal contaminated areas of agricultural plants and soils with the above mentioned biologically hazardous substances and to work up of appropriate protective recommendations.
The topicality of the Project is determined by:
1. Georgia is an agricultural country where viticulture, citrus growing, tea-growing, vegetable-growing, crops, melon-growing are developed. The country’s population consumes agricultural products all the year round in great amount.
Georgia’s natural factors create favorable conditions for the hazardous organisms of animal and vegetable origin – insects, ticks, worms, mollusks, fungi, viruses, weeds, parasite plants, etc. They harm to plants and agricultural products. Proceeding from this, it is necessary to elaborate and conduct biorational measures against them.
2. An acute need in revealing of regularities of toxic elements behavior in the environment and persistent pesticides is also caused by the fact that Georgia’s territory is characterized by large forest tracts and huge stocks of drinking water including mineral waters.
At present time Georgia is in need of financial assistance for conducting investigations meeting up-to-date standards and for monitoring the contamination of plant cover and soils and their products with biologically hazardous substances, pesticides amounts of various biocenoses, and develop a corresponding concept in relation to regularities of the contamination of crops and soils.
The new and distinguishing feature of the given Project is its participants’ intention, on the basis of comparison of the data obtained in the earlier investigations with those obtained in the process of the implementation of the Project to determine the dynamics of contamination with toxic elements and residual amounts.
The scientific novelty of the Project consists in detection of the peculiarities of degradation and translocation of toxic elements and persistent pesticides of Georgia’s agricultural plants, crops and their products and soils and generalization of the results to be obtained in the investigation of the environmental contamination with them.
The practical value of the Project results comprises:
- determination of the levels of contamination of the regions to be investigated with biologically hazardous substances;
- detection of the regularities of this very type of contamination of agricultural plants their products and soils and drawing up corresponding recommendations on the basis of obtained results.
The economic benefit of realization of the Project is expected to follow from the possibility to obtain, on the basis of proper use of the results obtained, protection of plants from hazardous organisms and obtaining of high-quality crops, which, in its turn, is expected to enable the State and farmers to produce “pure”, high quality agricultural products for both internal consumption and abroad.
From the ecological point of view, the Project is of particular importance. In each biocenosis and in each of its components corresponding actions on decontamination and improvement of the environment are expected to be realizable.
The Project is of great importance from the humane point of view, because the use of the results obtained is expected to provide the ecologists and protectors of natural resources with recommendations about anticipated negative consequences of contamination of crops, their products and environment with biologically hazardous substances.
