Increasing soil pollution has become a global problem because it threatens the production of safe food. In addition, pollutants from the soil through plants, water and air enter the food chains and cycles of matter circulation. A modern approach to the recovery of polluted soils is increasingly focusing on so called green technology - phytoremediation, which is relatively cheap, noninvasive and environmental friendly technique because it uses the metabolic processes in higher plants and their rhizosphere microorganisms to remove, immobilize, degrade or decompose pollutants, therewithal preserving the productive properties of soil. Phytoextraction is a phytoremediation technique that stands out for its performance. It removes inorganic contaminants by root uptake and accumulation in plant biomass, which is being removed after vegetation period by standard agrotechnical measures. Sunflower is a crop that is gaining increasing importance in remediation technology for several reasons: it has high ability of up taking, translocating and accumulating inorganic pollutants, can decompose certain organic pollutants, produces a significant amount of biomass, and presents a raw material for biodiesel production.
