作者报道了尿中无机砷(InAs)、一甲基胂酸(MMAA)及二甲基次胂酸(DMAA)等代谢物的分离及各成份还原成砷化氢后用原子吸收光谱法(AAS)的测定。另外,也探讨了非职业性接触砷化物和正常人吃富含有机砷海产品后尿砷的变化情况。标准和试剂: 标准溶液:用砷酸钠、MMAA及DMAA制备。尚有硼氢化钠(BDH)、醋酸盐缓冲液
The authors reported the separation of metabolites such as urinary inorganic arsenic (InAs), monomethylarsonic acid (MMAA) and dimethylarsinic acid (DMAA) and the subsequent reduction to arsine by atomic absorption spectrometry (AAS ) Measurement. In addition, the changes of urinary arsenic in arsenic-rich and non-occupational exposure to arsenic-rich organic products were also discussed. Standards and Reagents: Standard solution: Prepared with sodium arsenate, MMAA and DMAA. There are sodium borohydride (BDH), acetate buffer
