Simultaneous determination of inorganic arsenic species in a pore water, paddy soil, and rice by using ion chromatography with inductively coupled plasma mass spectrometry

摘要

This study focused on the determination of inorganic arsenic species in rice which were produced in several places in Korea. If existed, to identify the source of inorganic arsenics, the surrounding paddy soil and pore water were analyzed. The developed method for the quantitative determination of As species included the selective extraction method, the optimum separation and detection method, and all the important instrumental and methodological parameters. The prevention of loss and transformation of As species was confirmed with the developed extraction and analytical method.
