Abstract

We have monitored Arsenic (As) content of 200 white rice samples and 100 brown rice samples produced in Korea. The total arsenic content in samples was analyzed by Inductively Coupled Plasma-Mass Spectrometry ICP-MS after microwave assisted digestion. Arsenic speciation i.e. As^III, As^V, DMA, MMA was determined by wet-sonication and HPLC-ICP-MS. The major compound among As species in rice is an inorganic arsenic (As^III, As^V). The proportion of inorganic As/total As is respectively 68.45% in white rice and 72.46% in brown rice. We confirmed that all white rice samples were lower than CODEX standard (0.2 mg/kg).
