Southern Kazakhstan, ways of soil detoxication in Turkistan town on the basis of plants – hyper – accumulators

The anthropogenic soil pollution is a rather actual problem because the life on the earth exists at the expense of it. The most dangerous substances for soil are heavy metals (HM). In this research work we have studied the sources of heavy metals’ penetration into the soil system of Turkistan district, Southern Kazakhstan and also the ways of extraction with the help of plants – hyper – accumulators. This method of soil and environment purification was called as phytoremediation – Greek “phyton” (plant) and Latin “remedium” (to restore). Phytoremediation became effective and economically favourable method of purification when it was discovered that plants – hyper – accumulators could accumulate in their leaves about 5 % of nikel, zink and copper (dry weight). We have taken wheat (Triticum), barley (Hordeum), sunflower (Helianthus), buckwheat (Fagopyrum), maize (…. indentata), soya bean (Glycine) and mustard (Brassica juncea).
Key words: antropogenic pollution; heavy metals; the accumulation of heavy metals; plants – hyper – accumulators; phytoremedy; carcinogens; pesticides; humus; soil erosion.
