Abstract

Toxic and essential metal element content of ten different spices of China were determined by ICP-MS after microwave digestion method.The validation of the presented procedure is performed by the analysis of standard reference material.The relative standard deviations were found to be lower than 5%,and the recovery values were 83.4%～115%.The contents of K,Ca,Mg,Mn,Fe are rich in all the spices,the content of As is high in ginger and the content of Pb is high in cassia and prickly ash.
