Cu hyperaccumulators in mining area

Abstract

Abstract: Plant species distributing in three Cu mining area were investigated, and Cu concentrations in soils and plants were analyzed. The results showed that Cu ore deposit mostly was distributed at the altitude of about 630 m. Elsholtzia splendens and Rumex acetosa were distributed only on the Cu ore deposit or the place with high Cu concentration, and the maximum Cu concentrations in these two plants were 1060 mg穔g-1 DWand 1006 mg穔g-1 DW, which reached the critical of hyperaccumulator. Cu accumulations in Elsholtzia splendens and Rumex acetosa were positively and closely correlated with Cu concentration in soil.

Key words: Mining area, Cu hyperaccumulators, Elsholtzia splendens, Rumex acetosa
