Abstract: The content of Pb and Cd in Portulaca oleracea growing in soils contaminated by heavy metal were investigated by flame atomic absorption spectrophotometer(FAAS). The results showed that P. oleracea had strong extraction performance for the heavy metal ions in contaminated soils. And the extraction performance of P. oleracea to Cd was superior than that to Pb.

Key words: heavy metal, contaminated soils, Portulaca oleracea, herbaceous plant
