Summary of "Analysis of Arsenic Species in Processed Rice Bran Products Using HPLC-ICP-MS."

The purpose of this study was to compare the content of arsenic species (As(V), monomethylarsonic acid [MMA], As(III), and dimethylarsinic acid [DMA]) in products, such as bran powder and tablets, using high-performance liquid chromatography-inductively coupled plasma mass spectrometry, and to determine the risk of human exposure to inorganic arsenic (iAs). The products presented As(III) > As(V) > DMA > MMA, at 241.03 to 579.35, 43.41 to 271.91, 15.16 to 30.43, and limit of quantification to 14.31 μg/kg, respectively. The contents of arsenic species tended to differ among the products (P < 0.05). When the maximum level (0.2 mg/kg) of iAs in white rice was applied to products, it exceeded 1.4 to 3.3 times as 284.43 to 767.10 μg/kg. Also, if more than 109.42 g/day of rice bran powder product containing 767.10 μg/kg as iAs was ingested, the provisional tolerable weekly intake (9.0 μg/kg body weight/wk) was exceeded.
