收集我国6个主稻作区代表性稻谷样品120份,采用原子吸收光谱法测定Cd、Pb含量,分析各地区各品种稻谷及其加工产物Cd、Pb含量差异,探讨Cd、Pb在稻谷、精米、米糠和米糠油中的分布规律。结果表明,我国主稻作区稻谷、精米、米糠和米糠油中Cd平均含量分别为(0.116±0.057)、(0.089±0.413)、(0.149±0.069)和(0.111±0.043) mg·kg~(-1),且华中稻作区、华南稻作区、华北稻作区、西北稻作区、东北稻作区和西南稻作区稻谷及其加工产物Cd平均含量依次降低;稻谷、精米、米糠和米糠油中Pb平均含量分别为(0.232±0.105)、(0.125±0.061)、(0.301±0.142)和(0.089±0.024) mg·kg~(-1),华中稻作区、华南稻作...

A total of 120 samples of rough rice were collected from 6 main rice cultivation areas in China for analysis of content and distribution of Cd and Pb in the grains using atomic absorption spectrometry. Results show that the average Cd content in rough rice, milled rice, rice bran and rice bran oil was (0.116 ± 0.057), (0.089 ± 0.413), (0.149 ± 0.069), and (0.111 ± 0.043) mg · kg-1, respectively, and that the six main rice cultivation areas followed a descending order of Central China, South China, North China, Northwest China, Northeast Ch...
