Phytoremediation is an altemative technology to remove heavy metals in contaminated soil. Vetiver grass (Vetiveria zizanioides (Linn.) Nash) was used for Cadmium (Cd) and Lead (Pb) · removal experiments in 4 various soil types: {SI) sandy soil with abundant organic matter; (82) sandy soil with poor organic matter; (83) clay soil with abundant organic matter; (84) clay soil with poor organic matter. Plants were grown for 30 days before transferring to experimental pots. Pb(N03)2 solution was added to Ihe soil types in each experimental pot at O, 100, 300 and 700ppm; similarly CdC12 : O, l O, 30 and 60ppm | VNU Journal of Science Earth Sciences 25 2009 98-103 Phytoremediation of Cadmium and Lead contaminated soil types by Vetiver grass Vo Van Minh1 Le Van Khoa2 1 Danang University of Education 2 College of Science VNU Received 11 July 2009 received in revised form 22 July 2009 Abstract Phytoremediation is an alternative technology to remove heavy metals in contaminated soil. Vetiver grass Vetiveria zizanioides Linn. Nash was used for Cadmium Cd and Lead Pb removal experiments in 4 various soil types SI sandy soil with abundant organic matter S2 sandy soil with poor organic matter S3 clay soil with abundant organic matter S4 clay soil with poor organic matter. Plants were grown for 30 days before transferring to experimental pots. Pb NO3 2 solution was added to the soil types in each experimental pot at 0 100 300 and 700ppm similarly CdCl2 0 10 30 and 60ppm. Plants were observed for theừ growth and harvested after 3 months. Cd and Pb accumulation in roots and shoots was analyzed. The results showed that Vetiver grass grew in 4 various soil types. The statistical analysis indicated that vetiver s uptake ability of Cd and Pb increase as the level of Pb Cd in various soil types increase. Cd accumulation rates between shoots and roots of vetiver grass were fairly low on the contrary the accumulation rates of Pb shoot root is veiy high . Therefore vetiver grass can use to phytoextration of Pb and phytostabilization of Cd. Keywords Phytoremediation Vetiver Cadmium Lead Contaminated soil. 1. Introduction Heavy metal contamination is caused by various sources such as industrial processes manufacturing disposal of industrial and domestic refuse and agricultural practices. Phytoremediation is considered an innovative economical and environmentally compatible solution for remediating some of heavy metal contaminated sites 3 4 . The main factors controlling the ability of phytoremediation are plant species metal availability to plant roots Tel. 84-905234706 .
