title: [Absorption and accumulation of heavy metals by plants around a smelter].
abstract: The study on the absorption and accumulation of heavy metals lead, zinc, copper and cadmium by 8 plant species around a smelter showed that the metals accumulation by plants differed with plant species, their parts, and kinds of metals. Abutilon theophrasti had a higher capability of absorbing and accumulating Pb, Conyza canadensis, Ambrosia trifida, Polygonumn lapathifolium, A. theophrasti, Solanum nigrum, Chenopodium acuminatum and Helianthus tuberosus had a higher capability of absorbing and accumulating Zn, C. acuminatunz and A. theophrasti had a higher capability of absorbing and accumulating Cu, and S. nigrum, C. acuminatum, A. theophrasti, P. lapathifolium and C. canadensis had a higher capability of absorbing and accumulating Cd. These plants had TF values higher than 1, and were suitable for phytoextraction to remedy polluted soil. As for the plants with TF values lower than 1, they were suitable as the phytostabilizers of heavy metals-contaminated lands.
