Abstract：The preconcentration and determination of gold and silver in twenty plants from the copper mining area by ICP-MS was described. The plant samples were decomposed by dry-ashing and aqua regia. 107Ag，109Ag and 197Au were chosen as determining isotopes and 103Rh and 203Tl were chosen as interna1 standards. The conditions of sample digestion were elected and the interferences on instrument measurement were eliminated through the experiments. The detection limits of method were 0.048 and 1.06 ng·g-1 for Au and Ag. The precisions(n=5) were between 0.85% and 9.05% RSD，and the recoveries were between93.6%～101.6%(Au，Ag). The method is sensitive quick,simple and has been applied to the analysis of gold and silver in plants from the copper mining area. Under the given analytical conditions，the results showed that the contents of the Au and Ag varied in these diferent plants，the ranging between 0.181～0.99 ng·g-1 for Au and 280～2 150 ng·g-1 for Ag respectively. The geochemical anomalies on Ag were discovered in Pteris,Dicranopteris pedata and Bolbitis heteroclita, which can be regarded as prospecting effective indicator plants.
