[Determination of Pb, Cd, Hg and As in three sorts of Chinese traditional medicine treating tumor by ICP-MS].

A method was proposed to determine Pb, Cd, Hg and As in three sorts of Chinese traditional medicine treating tumor (Jinkehuaier, Huachansu and Fufangkushen) by ICP-MS. The result shows that the contents of the four elements Pb, Cd, Hg and As in these three sorts of Chinese traditional medicine treating tumor are low, which are all correspond with the import standard in Southeast Asia. The contents of Hg and As in Jinkehuaier are higher than the standard of U.S. FDA about drug and health food. ICP-MS is a quick and accurate method for the determination of Pb, Cd, Hg and As in Chinese traditional medicine.
