Abstract	Inorganic arsenic (iAs) in food is much more toxic than organic. Four arsenic species, arsenite (As$^{III}$), arsenate (As$^{V}$), monomethylarsonic acid (MMA), and dimethylarsenic acid (DMA) in polished rice cultivated at the mining areas of Korea were evaluated. A methanol-water (1:1) mixture was used for extraction of As compounds and an anion Hamilton PRP X-100 column for As species separation in HPLC-ICP-MS. The limits of detection were 5.3, 3.7, 19.2, and 3.7 ώg/kg on dry weight basis for As$^{III}$, As$^{V}$, MMA, and DMA, respectively. When this method was applied to eleven polished rice samples, the mean value of iAs content in total As was approximately 57%.
