We compared the official method using AAS or with our new quick heavy metal measuring system based on voltammetry method. Then we considered whether analysis of cadmium on paddy-rice investigation was possible. As for the measurement of heavy metals by microcartridge type electrochemistry analysis machine, measurement was possible in lower than 10 ppb which was Japanese reference value easily, and manipulation was simple and easy. Also we examined the influence that we used a pumpkin as a clue of a heavy metal detoxication mechanism by this study, and Mn presence gave glutathione dosage in one of the defence materials in Pb accumulation dosage in Pb exposition and microelement and organism. As a result, Mn presence affected rhizoma interlobar Ca distribution. In addition, Mn free experiment area showed a rise of GSH/GSSG rate in leaf region conspicuously. In Pb concentration(400 ppm), it compared it with Mn presence experiment area in Mn free experiment area and decreased conspicuously. From these results, it was suggested that Mn functions for an action of a glutathione-related enzymatic group.

我们将使用 AAS 的官方方法或基于伏安法的新型快速重金属测量系统进行了比较。然后我们考虑是否可以对水稻调查中的镉进行分析。使用微盒式电化学分析机测定重金属时，可轻松测定日本参考值10ppb以下的浓度，且操作简便。另外，本研究还考察了以南瓜为线索的重金属解毒机制，以及Mn的存在对Pb暴露中的Pb积累剂量以及微量元素和生物体中的防御材料之一的谷胱甘肽剂量的影响。因此，Mn 的存在影响了根茎叶间 Ca 的分布。此外，无锰实验区叶区GSH/GSSG率明显上升。在Pb浓度(400ppm)下，无Mn实验区与有Mn实验区相比明显下降。由这些结果表明，Mn具有谷胱甘肽相关酶基团的作用。
