An ICP AES method was established for the determination of 14 elements in chromium rich and normal brewer′s yeast.The RSDs of two standard reference materials were 0 5% 3 2% and 0 4% 3 4%,respectively.The results showed that chromium contents could affect the concentrations of other elements in chromium rich brewer′s yeast.The concentrations of K,Mn,P,V,Mg and Ca in chromium rich brewer′s yeast were significantly lower than those in normal brewer′s yeast.
