Tóm tắt

Phytoremediation is an alternative approach, that has attracted researchers and government concerns to against heavy metals pollution in soil. Phytoremediation is concerned as the next generation technique since itself is inexpensive fee, comfortable, and friendly to the environment. Sunflower and vetiver grass are known as the “hyperaccumulators” and effectively remove the trace of Lead (Pb) contamination. In this three-months study, the phytoremediation efficiency of sunflower MV-005 and Vetiver grass were evaluated in conditions of high/ mild/ low soil Pb (4000 ppm, 2000 ppm and 1000 ppm). Results confirmed the advantages of sunflower in soil Pb elimination as compared to Vetiver. Furthermore, amendment of effective microorganisms (EMs) facilitates sunflower MV-005 growth and the phytoremediation efficiency. This study, for the first evidence, provides the comparison between sunflower MV-005 and Vetiver grass in soil Pb elimination and opens new trend of research in sunflower based phytoremediation amended by EM.
