加工粮样因碾轧度不一,并可能带有污染,不利于水土病因分析,故本试验所分析的样品均为原粮。共分析样品83个,其中病区38个(黑龙江尚志县24、四川冕宁县7、陕西黄陵县7);非病区45个(北京16、浙江临安县6、陕西绥德4、黑龙江呼兰县12、四川自贡市郊区7)。考虑各地饮食习惯,分析粮样为玉米、稻米、小麦、黄豆、土豆五个品种。测定元素项目为Zn、Cu、Mn、Fe和Mo,除Mo用极谱催化波方法外,其余均用原子吸收光谱法测定。
Due to the different degree of grinding and the contamination of the processed grain sample, which is not conducive to the analysis of the causes of soil and water, the samples analyzed in this experiment are all raw grains. A total of 83 samples were analyzed, including 38 wards (Heilongjiang Shangzhi county 24, Sichuan Suining county 7, Shaanxi Huangling county 7); non-endemic areas 45 (Beijing 16, Zhejiang Lin’an County 6, Shaanxi Shunde 4, Heilongjiang province Lanxian County 12. Suburbs of Zigong City, Sichuan Province 7). Consider eating habits around the country and analyze grain samples for corn, rice, wheat, soybeans and potatoes. The elements of the determination elements are Zn, Cu, Mn, Fe, and Mo. All of them are determined by atomic absorption spectrometry except for Mo using polarographic catalytic wave method.
