Uptake capacity of metals (Al, Cu, Pb, Sn, Zn) by Vetiveria zizanioides in contaminated water from Dong Xam metal production trade village, Thai Binh, Vietnam

The present study investigates an experiment of uptake capacity of metals by Vetiveria zizanioides to treat contaminated water from a metal production trade village, Dong Xam, Thai Binh, Vietnam (DXV). Vetiver was grown in two pot culture experiments TB10, TB6 with solutions containing respective concentrations of Al, Cu, Pb, Sn and Zn of 2.5, 55.6, 0.15, 7.7 and 24.4 mg from the DXV for a period of 36 days. | Vietnam Journal of Earth Sciences, 38(3), 286-296, DOI: 10.15625/0866-7187/38/3/8763 Vietnam Academy of Science and Technology Vietnam Journal of Earth Sciences (VAST) http://www.vjs.ac.vn/index.php/jse Uptake capacity of metals (Al, Cu, Pb, Sn, Zn) by Vetiveria zizanioides in contaminated water from Dong Xam metal production trade village, Thai Binh, Vietnam Nguyen Trung Minh1,*, Seong-Taek Yun2, Jang-Soon Kwon2, Doan Thu Tra3 and Doan Dinh Hung1 1 Vietnam National Museum of Nature (VNMN), Vietnam Academy of Science and Technology 2 Department of Earth & Environmental Sciences, Korea University 3 Institute of Geological Sciences, Vietnam Academy of Science and Technology, Hanoi, Vietnam Received 15 November 2014. Accepted 20 August 2016 ABSTRACT The present study investigates an experiment of uptake capacity of metals by Vetiveria zizanioides to treat contaminated water from a metal production trade village, Dong Xam, Thai Binh, Vietnam (DXV). Vetiver was grown in two pot culture experiments TB10, TB6 with solutions containing respective concentrations of Al, Cu, Pb, Sn and Zn of 2.5, 55.6, 0.15, 7.7 and 24.4 mg from the DXV for a period of 36 days. Vetiver was higher tolerant to metals Al, Cu, Pb, Sn and Zn than other plant species. The roots (hereafter R) accumulated Al from 17 to 30 folds than that in “reference plant”. The upper parts of shoots (hereafter S1, S2, and S3) were 1.2 folds higher than that in “reference plant”. Cu concentrations in the roots and shoots were 660 and 46.2 mg/kg, respectively. Vetiver could withstand and survive at Cu concentration of 46 mg/L in contaminated water that is markedly higher than other plants. The translocation of Pb from root to shoot was 41%. Sn accumulated higher in the top, in which shoot/root ratio varied from 82 to 277%, and increased to the top by order S3/R>S2/R>S1/R. Zn could be translocated from root and accumulated in shoot. The ratio shoot/root was up to 46%. The present results demonstrated that .
