Bioindication of soil pollution with Cu, Zn and As by roots of plants

Plants growing on soils enriched with metals and metalloids are usually genetically tolerant to high concentrations, and have excellent adaptation abilities to extreme environmental conditions. That fact in combination with the extreme soil pollution in the town of Bor and the surroundings, gave a good basis for the environmental research. Assessment of pine, linden and elder roots ability to indicate soil enrichment with Cu, Zn and As was conducted. Samples were colected at the sites seleceted in regard to the vicinity of the copper smelter, flotation tailing ponds, overburden dumps and open pits. It was observed that linden and elder, unlike pine roots, had ablity to indicate soil enrichment with Cu, Zn and As, which was the most obvious at the sites with the highest metal/metalloid contents. On the other hand, pine roots have developed the mechanisms for resistance to As accumulation in the roots, especially in the conditions of high As soil content.
