Effects of amendments of N, P, Fe on phytoextraction of Cd, Pb, Cu, and Zn in soil of Zhangshi by mustard, cabbage, and sugar beet
10.1002/tox.20291.abs
Soil contaminated with Cd, Pb, Cu, and Zn in the Zhangshi irrigation area is very hard to be remediated. Phytoextraction is considered as an efficient method to remove these toxic metals from soil. In the present study, three vegetables including sugar beet (Beta vulgaris), mustard (Brassica juncea L.), and cabbage (Brassica oleracea L. var. capitata Linn.) were used to bioaccumulate heavy metals in soil through pots experiment for 90 days; and nutrient elements were applied to stimulate the phytoextraction of metals. Results of bioconcentration factors (BCF) and translocation factors (TF) from this study showed that these plants could phytoextract heavy metals, but the accumulation and translocation of metals differed with species of plants, categories of heavy metals, and some environmental conditions (e.g. nutrients). Meanwhile, the addition of nutrient elements, such as N, P, and Fe, could affect the phytoremediation of heavy metals via promoting the normal metabolism of vegetables or changing forms of metals. Results of this study could provide some available information for in‐site bioremediation of soil from Zhangshi irrigation area. © 2007 Wiley Periodicals, Inc. Environ Toxicol 22: 565–571, 2007.
