摘　　要：采用电感耦合等离子体发射光谱法(ICP-AES)和电感耦合等离子体质谱法(ICP-MS)测定了有机大米和常规大米中Ca、Fe、K、Mg、Mn、Na、P、S、Si、Zn、As、Cd、Hg、Pb、Se、Cr等16种矿质元素的含量并对数据进行了方差分析.结果表明,两者矿质元素含量存在同异性,Ca、Fe、K、Mg、Mn、Na、P、S、Si、Zn、Se、Cd含量比较接近,重金属元素As、Hg、Pb、Cr在有机大米和常规大米中存在显著差异.The contents of 16 kinds of mineral elements, such as Ca, Fe, K, Mg, Mn, Na, P, S, Si, Zn, As, Cd, Hg, Pb, Se and Cr, in organic rice and conventional rice were determined by ICP-AES and ICP-MS, and the measurement data was subjected to variance analysis. The results showed that the organic rice and the conventional rice were similar in the contents of Ca, Fe, K, Mg, Mn,Na, P, S, Si, Zn, Se and Cd, but had remarkable difference in the contents of heaw metal elements As. Hg. Pb and Cr
