%X The concentration of five kinds of heavy metals (Mn, Pb, Ni, Cu, and Cd) in soil and 12 species of plants, belonging to 6 families and growing on spoiled heap from steel refinery in Panzihua, was measured with atomic absorption spectrophotometry, the bio-accumulation coefficient (AC) and bio-transfer coefficient (TC) of these plants to heavy metals were further calculated. We found that the content of Mn in spoiled heap soil (up to 3869.14 mg/kg) was highest in five heavy metals, and the next in order was Pb> Ni > Cu >Cd. There was similar distribution of the five heavy metals both in plants and in soil. The value of AC of the tested dominant plants to heavy metals was low, however the value of TC relative high. The value of TC of Carpesium abrotanoides L. to Cu, Tridaxprocumbens L. to Pb, and Artemisia indica Willd to Cd, was 5.1, 3.3 and 6.0, respectively. Furthermore, the value of TC to Mn in 8 out of 12 species of plants exceeded 1. Our results provide reference species for greening and purifying for heavy metals spoiled soil, and offer selected objects for investigate the mechanism involving in tolerance of plants to heavy metals.
