Abstract: Concentrations of Cr, Pb, Zn, Cd, Hg and As in Eupatorium adenophorum and its soil, which collected from Shui Yindong gold deposit in Guizhou, were analyzed using the Atomic Absorption Spectrometry. The results showed that the soil in this research area was seriously contaminated with extremely high heavy metal’s concentration of Hg(12.575 mg·kg-1) and As (501.374 mg·kg-1). Compared to soil environmental quality standards of China (GB15618-1995), the average concentrations of Hg and As were 8.383 and 12.534 times higher, respectively. The results showed that this area had been seriously contaminated by Hg and As. The enrichment ability of E. adenophorum to Cr, Pb, Zn, Cd, Hg and As were quite different. Especially, it could accumulate Cr intensively. The absorbability migration abilities to heavy metals Cr, Pb, Zn, Cd, Hg and As of E. adenophorum were also obviously different. The absorbability migration abilities to Pb, Zn, Cr of E. adenophorum were very strong. The absorbability migration abilities to heavy metals of the stem and leaf of E. adenophorum were also obviously different. The absorbability migration ability to Cr,Pb and Cd of its stem were very strong while it to Zn,Pb and Hg of its leaf were very strong. E. adenophorum is very significant for the entironment revegetation of this mine as its tolerance to Cr, Pb, Zn, Cd, Hg except for As.

Key words: Eupatorium adenophorum, heavy metal, element mensuration, enrichment, tolerance
