Abstract

Cu, Zn, Pb and Cd content and pollution index of whole plant of Polygonum viviparum Linn. and Rumex nepalensis Spreng. in mine area of Central Tibet were determined and analyzed. The results show that Cu, Zn, Pb and Cd contents in P. viviparum and R. nepalensis are 10. 86, 45. 36, 3. 87 and 2. 71 mg·kg-1 , 21. 77, 94. 73, 6. 78 and 2. 04 mg·kg-1 , respectively. Pollution indexes of Zn and Cd in P. viviparum and those of Cu, Zn, Pb and Cd in R. nepalensis are more than 1, indicating that two species tested are polluted by Cu, Zn, Pb and Cd pollutants. Otherwise, R. nepalensis appears a stronger accumulation ability to Cu, Zn and Pb in soil.
