英文摘要:

Chinese traditional medicine (CTM) containing realgar may contain high levels of toxic metals, such as arsenic, etc. The monitoring of trace elements, especially the harmful elements, is closely related to the quality control of the CTM. Three kinds of CTM containing realgar were digested by microwave method and electric heating plate method, and As, Hg, Cu, Cd and Pb were determined using ICP-MS and ICP-AES. In addition, this research determined the content of soluble heavy metals in the human gastrointestinal solution. The results showed that three kinds of CTM contained As of 24 350 similar to 68 627 mg.kg(-1); Hg of 0. 26 similar to 122 313.6 mg.kg(-1); Cu of 2. 04 similar to 6. 95 mg.kg(-1); Cd of 0.02 similar to 1. 46 mg.kg(-1); Pb of 0. 42 similar to 40. 60 mg.kg(-1). In comparison, the contents of soluble heavy metals in the human gastrointestinal solution are; As of 81 similar to 618 mg.L(-1); Hg of 0. 34 similar to 216 mg.L(-1); Cu of 1. 08 similar to 215 mg.L(-1), and Pb, Cd were not detected.
